What does THIS failure look like to you guys ? (a Myria LCD TV)
Greetings fellow cappers, quick and simple one today: got this Myria....thing....junk-dive LCD which has some color problems and was wondering what you guys think the fault is: panel or T-CON board. The pictures don't do it justice too well, since cameras don't "see" screens the same way our eyes do, so I'll try my best to describe it: basically the colors are a bit messed up 
It's most visible in the picture with the home screen of an android box I use for testing: notice how the background has a highly uneven color when it should look like THIS. The whole thing seems to have a tint of purple to it and there's also "ghosting" going on (when an image changes suddenly, such as a menu going away, it leaves behind a grayish-purple afterimage that takes quite a while to disappear). Forgot to mention it affects all inputs. Don't know how else to describe it but it all boils down to two issues: bad T-con or bad panel. Now while I was taking those pictures, it had been running for like 5-10 minutes and at one point the colors suddenly improved slightly ! They weren't brilliant, but definitely better, especially on those SMPTE test patterns.
I got to the T-con which was buried underneath tons of metal and identified the gamma chip which I read is usually the cause of such "solarized' picture. I know you can't see it, but it's an AS15F chip. A fellow of mine tried blasting it with some flux and hot air but nothing changed, but that could very well be because he did a sloppy job - I feel like he didn't heat it long enough. I will try taking over with actual solder and a soldering iron, but before I do that, what does this look to you : is it worth the struggle, or is the chip busted (or perhaps the panel ?) :| I'll start measuring those test pads as suggested in another thread around here if need be, but for now just let me know if I'm on the right track. It's such a bullshit designed TV that I can't really access the T-CON with the TV fully assembled, since it's placed under a metal chassis that holds the power supply and logic boards, so it's not gonna be easy to run it and measure it at the same time
Cheers.
