My monitor was strobing; no bands of color, no grids or distortion, et cetera, just a rapid on/off strobe effect. So, I opened her up and (after confirming all the caps were in good shape) I baked my board at 375 for 8 minutes as so many others here have. Unfortunately after re-assembly, the situation has worsened. There is no picture at all now. Instead, the monitor simply cycles through full-screen fields of solor colors: red > green > blue > black > white > red > green > blue > black > white....ad infinitum.
Thoughts? I am going to try re-baking it a higher temperature, but I suspect this all means that the board is simply tits up. Of course, now I need to decide if I should spend the $100 on an eBay replacement, or just write the whole thing off as a loss...
Personally I'd write it off - with new HP Omen 32" VA monitors at $400 US it doesn't make sense to stick your neck out on something you *KNOW* will die again at some point.
When my Samsung 305T died (internal PSU blew and fried the circuit boards) I replaced it with a used HP Zr30 - apart from not being a ticking time bomb it has DisplayPort so I could start weaning off all my DP-DVI adapters. At $250 CDN it was absolutely worth it.
Lately I have been seeing used 30" monitors (DVI only) go for as little as $175 CDN.
Hey guys, I wrote some tutorial about heating the TCon with a 40W lamp and decided to give some update on that for people who didn't give up.
crashnburn asked about how is it working and did I make some mods.
Well, over the years I got very efficient at doing it. I now use a flat 36W 12V halogen lamp for the heating. Fixing the monitor takes me about 15min. Now that I have a dozen of procedures I can say that my method is somewhat unreliable but not bad. My repairs last for very different amounts of time. Sometimes the monitor would flicker just 1 hour after but I also got some very long periods of 1 year or so, without problems. The problem is I don't know if I am melting the solder beneath. These long periods seem to be when I heat the chip more but I also don't want to overheat it. At this present time I heat the cheap while the monitor is working, so I see the moment when it stops flickering. I heat the chip for about 3-5 minutes after I see that it stops to flicker. Just now I did another reheating for 3 minutes and it worked only for about an hour, so I guess it needs more. I just forget how much time it needs. One of the long periods I remember that I heated it 8 minutes after the stop of flickering.
I didn't mod it for better cooling but I did put a fan that blows on the plate. I don't use the back cover of the monitor. Well, I don't know what to say. That's how it is. Sometimes it last 1 year, sometimes 1 hour but overall it is not that bad, 3-4 heating procedures for the year or less.
I really like this monitor, it is big with nice MVA panel. I can't buy a replacement. I am am doing graphics on it, it is very evenly lit and the color is very accurate although it lacks adjustment. I want to use it, so I fight for it!
I think reballing it is a good way to go but people who do reballing want too much money here in Bulgaria. The board itself costs less and they don't guarantee success. Maybe I should reball it and go on but everytime it flickers I just fix it.
I am sorry for those who asked me questions but I don't visit this forum regularly. My 40W halogen lamp method does work every time but the working period after that is still a gamble but as I said, I think it's worth it.
