Samsung lw32a23wx plasma tv, Low color depth, flickering
Hello,
I have this ancient plasma tv from 2004. I considered it dead because around 6 years ago it started making loud clicks and shutting down.
When it opened (6 years ago) there was no picture, only vertical red,green and blue lines. We got a new tv and never bothered with repairing it.
Anyway, i decided to open it up again yesterday to see if it was worth repairing myself. Oddly, it opened and showed picture (almost) immidiately. It seems like the color depth has droped,as it looks like a 256 bit image, here and here . I thought maybe it was someting with the contrast,brightness etc settings, but no.There is also some horizontal lines flickering like this.
I opened it up today again. The picture was horrible for about 10 minutes, then begun getting bettter to the point it was yesterday.
I read the forum post about plasma tv troubleshooting by tom66, checked for bad capacitors and fuses bad i didn't find any, maybe because i am a newbie.
If anyone has any idea about what is causing this, please share and thanks in advance.
