And my 43" Viewsonic 4K VX-4380 also just arrived this afternoon. I am also very happy w/ this model so far. Just the fact that I don't have to see the graphics all mess up the way philips boot up, is priceless
That was the most annoying thing about the Phillips monitor.....that constant handshake issue at boot up. Sometimes I just wanted to check something really quick on my PC. But nooooo...I had to wait for the damn monitor to sort out its display.

Thermal failure, all of the main failed ones are on a void.. And up top where most heat is.
You would expect an LED manufacturer would know how to heatsink a LED or was it AUO? Either way glad I didn't go for one of these.
You need quite high temp to brown sillicone lenses like that, shitty design.
But yes easily replaced if that led is off shelf or a common current and brightness or you replace the lot.

I'd get custom mbpcbs made with the right led pitch. But I've been building leds for over a decade..
Osram ssl80 might do the trick without reflectors but no gurantee. It could also be to reduce hot spots.

Also that reflector design could be very hard to source or replicate on 2nd look... Good luck.
UPDATE: I decided against shipping my monitor out to get fixed. As it turns out my credit card company will only extent the manufacturers warranty if their warranty is three years or less.....the Phillips warranty is four years. So, I decided to open it up and see what was going on. Obviously I knew it was a back lighting issue since it went completely blank. You really have to do some digging to get to the back lighting strips. When I got there, over half of them looked brown and burnt. The strips themselves would be super easy to replace. They just have basic screws holding them down and they plug/unplug quite easily. Looking at my photos you can easily see the burned out areas. I don't know if the strips could be replaced and it would work fine, or if something upstream has malfunctioned and cause the issue.

My one did begin to fail at the top like you said.
a few quick questions:

1) if we replace it, how long would the replacement last?

2) where do you buy mbpcbs and osram ssl80?

3) what "reflector design"?

Led-tech.de

If you use thicker mbpcb it should out last the rest of the design .

Reflector (what looks like a rough/uniformity reflector) is the large reflective circle around the led. Not something I'm used to.
Maybe send them a photo and explain there could be a few of you looking for these. Need to figure out current and voltage of a working string though. Also figuring out light output angle of the led is a good idea.

Hey. I am having the exact same issue.
looks like the backlight died. If I shine a flashlight into the tv I can see images.

I’d love to repair it but have no idea where to order these LED strips from. Can’t find anything on eBay etc.

Here's my update: I contact Phlips again, it's very strange, it looks like Philips does NOT repair their own monitor, since Philips at 1 time, join venture w/ LG to form LG Philips, it's hard to believe they can't fix their own monitor.

Anyhoo, they said they don't do that and ask me to contact a co. called Encompass, which is clearly a Philips authorized service center. A woman named Judy, who's the Logistics Director answered my email in 1 sentence: "They won't repair anything NOT under warranty"

I then find this link:

https://www.service-center-locator.com/philips/philips-service-center.htm
I have made at least 1 dozen phone calls. I picked the largest city / State like Los Angeles, Colorado, etc. And this is annother strange outcome: In all of those phone calls, most of them are disconnected and no longer in services, some Philips service center, ring once, then the phone went silent, then I also call the NON-Philips name authorized service centers, again, disconnected / no longer in service. There is not 1 phone connection that goes anywhere. Almost as if that service center list are many years out of date

Now, here's the good news, my insurance co. sent me the cheque today on the full amt. of my purchase thru extended warranty.

NEVER touch a Philips again.

Ugh, these reports of failing backlights just outside of warranty period are starting to worry me a bit.

I've noticed a definite shimmer at the top of the screen when I turn the monitor on, which disappears after an hour or so.

Anyway, I think I'll need a new screen soon, but nothing currently available appeals to me. So I hope it doesn't die just yet...

is your monitor under warranty? IS it the 40" or the 43"?

the people in this group who bought the 43" version of this same screen should read these last few pages of this thread
