SDM-HS94P Backlight Bleeding Problem

emerge said:
Are you sure you don't have this problem in native resolution? This seems strange. You are saying the problem occurs only when you are not in native resolution?

It should occur in every resolution, its a monitor specific thing.
Exactly. There should be no difference since no matter what resolution you use, the monitor is still displaying 1280x1024 pixels.

mentorxxx. Try looking at a completely black background with lights in the room turned off. Do you see the backlight leaking in native resolution too?

For example in this forum (that uses a black background)do you have problems ?
i see it perfectly ,colors are the same in every place of the screen and the black is
the same in all of the screen. Tried also with lights off . No problem.
The only problem i might have when reading this forum is that with lights ON, the
black background has a little more reflection than other websites have,nothing more.
 
So - what are the "newer revisions" exactly? Mine does this to some degree, although it doesn't bother me all that much. The funny thing is that my girlfriend's ancient 2nd gen LCD looks great from every angle, although it's response time is horrible, so it's a non option for gaming.

For gaming I'm loving this Sony, but I've got a dead pixel and the backlight is annoying as I can't seem to find a setting for web browsing that doesn't either hurt my eyes or looks too bright.

I haven't checked my monitor's revision date yet, but on the back of it, it said September of 2004. What are the revision dates I should look for on the display and or the monitor's internal info panel.
 
Domingo, press and hold the menu button for at least 5 seconds, it should tell you something like 2004-xx where xx is the week number it was developed in 2004.

set the backlight profile to : USER
go to the menu then choose : Color sRGB and set backlight to 40
those are the best to choose for normal use ,browsing etc .

if you want to see photos or play games or see movies use the preset MIDDLE (or High)
backlight profile BUT with 6500K color .
 
I'll give that a shot. I really haven't had much time to play with many settings (damned work) - but is is easy to "save" color settings so I can switch between game/general use color settings with a single button or at least easily?

Lastly - if I do have issues, is it better to go back to the store I bought it and return it (hoping for a newer model) or Sony themselves?
 
I have the european version and have the same backlight leakage problems.
I only see leakage from the left and right part of the screen and the weird thing is, while the left part light is white, the right part emits a greenish gloom. Unfortunately i don't have a digital camera or i'd post a pic.
I also experience the slightly darker top part.

I think i'm gonna send it back.
Luckly there's a sony in my country and since i bought it from sony's online store, which is in belgium i think, i just hope they will let me return the monitor to their facilities instead of RMA'ing to belgium since mailling a 10Kg package abroad is very expensive.

My lcd was made in 2004-30.
And besides this problem, i'm very happy with this lcd, though i wouldn't mind if it was a tad less reflective.
Btw, anyone noticed the coating gives a kind of jaggie effect, like in games, to lines? I can see my curtains from the reflection of the monitor and if i move my head from left to right focusing the edge of the curtain, the edge gets full of jaggies from the movement, like a 3d game @ 640x480.
Maybe my coating is uneven.
 
I also have the SDM-94P.

Ive noticed this problem also when i first used it.

i adjusted the backlight to USER 10, this got rid of the problem. my other settings are:

Backlight 10
Contrast 85
Brightness 45
Color 9300K
Gamma 2
Sharpness 5

wow, that setup is very close to my bro's, same speakers, monitor, similar case and keyboard/mouse
 
I guess no matter what kind of settings you change nothing works. I tried your settings, the problem is still there. There is no way to fix this.

There are just too many people who have this problem. All people having the backlight problems must have defective units.

Sony has to admit to this problem.
 
maybe it is a manufacturing issue. But then we should all be intitled to replaces of new fixed versions... in a perfect world. I talked to my brother, but he wasn't home to check the specs, I'll have to try and go over one day. But like I've said before he hasn't had any complaints about it, he loves it. I do not know of his attention to detail, but I imagine it would near mine and something like that wouldnt' stand.
 
Once you know where and what to look for, you will see it!

My brother too does not seem to care at these things, he had these magnetic effects on both the left and right sides of his samsung CRT monitor, he didn't see them until I pointed it out, and it was there, very clear to see and created this moire effect that was too annoying.

Some people just don't care about these things, but they are there and they are screaming loudly at you.
 
I guess I got lucky. Just got mine tonight and it barely has an backlight leak compared to yours.

I would complain to Sony if I was any of you with a terrible backlight bleeding problem and try to rma it.

Looks awesome on my 6800 ultra killer rig.
 
You are the shiznit. The exact same settings as you use fixed the small bit of backlight bleeding I had. Widescreen movies now look freakin awesome. Thanks man. :D

>WP< $lipKnot, can you press the Menu button on your monitor for around 5 seconds until a small box pops-up. See the week number xx in 2004-xx

Thank you

Thank you

It says 2004-43
 
I'm exchanging mine tonight for another one so i'll post a reply to say how it compares.


By the way is anyone willing to take apart their screen to see if they can fix the backlight problem?
 
You would have to be brave to take it apart I am scared to dust the screen for fear of marking it up :) I also used the settings suggested by Liquid Cooled and they have eliminated the backlight bleed for me. Thanks guy :)

Looks like I'll have to try this. How's it work for normal browsing vs. games? Right now I just setup 2 profiles like mentorxxx suggested and have had decent luck with it, but obviously it would be nice to have an all-purpose mode for everything. Are the black's solid and not greyed out? I've found more than anything else that in a lot of modes that seem to look really good in well-lit areas in HL2, the darnkess and shadows come out grey.

From what I'm learning is that in general, LCD's are tricky for gaming. They look so much better at times, but there seems to be a lot more upkeep involved :)

tried also those but the backlight bleeding didn't change at all (compared to my settings
not the default ) + with those settings monitor was too bright and colors were a little washed-out ...

those still remain the best for me :

set the backlight profile to : USER
go to the menu then choose : Color sRGB and set backlight to 40
those are the best to choose for normal use ,browsing etc .

by setting color to sRGB contrast & brightness are automaticaly locked to a
default optimal setting , then you have just to play a little bit with ONLY the backlight
setting and decide which you like. By setting backlight to 10 you might not have
backlight bleeding (it's obvious because by setting it so low it's like switching it OFF )
however this will cause more glare ( =eyestrain) and not nice colors.

in my opinion backlight optimal setting should be between 30-40 , not less than 30 in
any case.
 
If you guys turn down the monitor like in those settings then dark colors blend together too much. There really isn't a way to get a perfect image without sacraficing something else.


Anyway i took my monitor back today and all the others in stock were from the same shipment, week 30-35 so i didn't bring one back. I asked best buy when they would be getting more in and they said they were supposed to get some in last week but sony has recalled the last few shipments. Kind of odd but it's something to think about.


EDIT: Oh and while talking to the employee he says some people have been using puddy or tape to go around the screens that have back light problems. It's supposed to fix the problem. Some one want to try?
 
Yeah, I don't think I'll be putting tape or putty on my lcd anytime soon... Anyway, the sRGB settings works pretty well with my backlight at 37 right now, thanks for that tip mentorxxx. I've found that even though you'd think you would get more leakage with the backlight up, I've found it better to have your backlight at least 30 or so as your brightness is what causes the most leakage and having that lower is better. A moderate backlight will help to compensate for a lower brightness and will add almost no backlight leakage as long as you don't go above 50 or so.

If we could get more evidence that the newer manufactured sony's don't have the leakage as bad that would be great. I called sony and they transferred me to a specialist who said he was aware of no such thing and that the leakage was normal. I'm not going to waste my time exchanging it in hopes for a better backlight just based on one person as I could end up with dead pixels, something I don't have now at least. Mine is week 38 btw and the leakage is there but not as bad as the photos on the first page of this thread. I'm guessing he had the brightness up pretty high though. There has to be some other people out there with ones that were manufactured after week 40 or so. To get the manufacture week hold the menu button down.
 
My brightness was at 43. My backlight was at 0. My contrast was at 100.

A lot of people have this leakage problem to some degree.
 
nervx,

How did you know that all the packages are from week 30 to 35, did you open them all?

Is there a way to find the week of production from the box without opening it?


Thanks
 
They only had 5 in stock and they said they all came with the same shipment including the two on display. After checking mine and the the two display models and seeing they were all dated the same week i figured there's a pretty good chance the others would be the same.


I called sony and they transferred me to a specialist who said he was aware of no such thing and that the leakage was normal

I contacted them twice, both times they said i should file an RMA request.
 
Well I just exchanged my week 38 sony at best buy for a new one in hopes of one with less backlight leakage and came out with a perfect one :) This one is week 44 and has NONE of the side leakage that my old one had like the pics on the first page of this discussion and only has very minor leakage on the bottom but isn't near as bad as my first one. I truly believe now that they did do something to the manufacturing process and second the earlier poster's post that you should indeed get one with week 44 or higher, not even 38 is high enough.
 
Actually mine is from week 43 and it had minor leakage on the bottom and the top.

Awesome, so 43 is the new low for the week number you want. Don't get me wrong mine does still have minor leakage on the top and bottom just like yours which is to be expected a little with all lcds but the side leakage is completely gone. Mine was almost as bad as the picture on the first page and the difference now is like night and day. So if anyone that has a week from 38 to 43 please let us know how it is. I can confirm that the problem was not fixed with the week 38's as I went through 2 of them, the first one had a couple of dead pixels and the bad light leakage while the second one just had the light leakage.
 
I bought a Sony HS94PS several days ago and i notice right and left backlight leakage.
Not a lot of leakage if you set the light < 50%.
The manufacturing week is 37

In fact this leakage don't worry me so much but i have an other problem; the top of the screen is darker than the bottom.

I'm using the predefined settings low and middle @ 6500k

By the way i don't understand how sRGB work; because sRGB seems to keep my previous light or contrast settings. For example if i set light to 70% and then select sRGB the screen remains bright, amazing....
 
Mines is week 38.. has some left and right but no dead pixels so im not about to complain, only time i see it is on a black background and i dont find myself looking ata black monitor too often :)
 
I was at Microcenter this weekend and took a look at the HS94P they had on display. I removed the wallpaper and set the desktop to black and did not notice any bleeding around the edges.
 
After trying out settings from both mentorxxx and liquid_cooled - I've tweaked them and found I like liquid_cooled's settings, but prefer to boost the backlight to 30'ish. mentorxxx's RGB setting is also very nice, however it's not good for gaming and requires me to change settings, whereas liquid's are more or less all purpose. I just use his settings for everything and control brightness from within a game itself.

As for the bleeding issue - nobody's setting has fixed that and in reality I'm not even sure it bothers me much honestly. I've got a week 39 monitor and it's certainly there. If someone can verify that Sony is definitely swapping monitors out for the week 44 ones that supposedly fix this I'll do it, however I'm pretty sure my local Best Buy isn't going to have any newer ones right now.

What's the process for dealing with Sony...and can they even promise that I'll get a new one or just *another* one? Is this problem enough for them to bother with or are they going to tell me this is just a "feature" of the monitor?

sure, as i said those settings are best for browsing and everyday use,
if i want to play games i just switch to the default "middle" setting,
BUT with 6500 color .

my monitor also has minor bleeding ,but it's barely visible when you use the
sRGB setting (Color sRGB , backlight 40 ). No dead pixels . So i won't RMA
a practically perfect monitor . There is a high risk to get one that is worse !!!

This is kind of what I'm thinking. I have the bleeding a little bit and I do have a single dead pixel (in a spot where I never see it), but would rather have that than one with a dead pixel in the center and a bleeding problem that's worse.

I'm still a sucker for my old CRT's color settings. I configured everything once and it's all purpose for browsing, games, pictures, etc. so I liked liquid_cooled's settings as they're the closest thing to single setting for everything. In a way I wish I could program 4 TOTALLY different profiles at a touch of a button, but sadly the high/medium/low settings all use the same color temp. setting. If I change it for one, it changes it for all three. For me Doom looks better with the 9300K setting, but HL2 looks better with 6500K. Even though l_c's setting is 9300, it's kind of a neutral setting when combined with the others, so it's a good mix.

I've got an extended warrenty from Best Buy so I think my plan will be to wait for either more pixels to die or some newer monitors to arrive in 2-3 months and THEN think about swapping...especially if they come out with a newer model to swap for.
 
My monitor has zero dead pixel, so in my opinion it's better to keep it.
By the way, what is the best settings to work under Windows ?
9300k ? I try the following settings; 9300k, backlight: 40, light: 45, constrast 80 but the white is a little too bright for my eyes...
 
Do you know if a software to control the lcd exists ?
I have such a software on my latest flat panel Nec 1880SX
It was very useful to go to the settings you want with a mouse click or a shotcut...
