Got this 47" tv a while ago. It powered up and I saw the W logo on the screen so I bought it for 15 dollars at the recycler.
Finally got around to looking at it today. Powered it up and hooked up a source to it. The colors were off. It was like looking at a 3 gun RPTV that has the alignment of the guns off so you end up with that weird wrong colors and so on. Even the colors in the menus weren't right.
I then tore it apart and looked at the mainboard and the power board. Everything looks good. No leaking caps or anything. I didn't touch either of the boards on the left/right (Inverter? Driver boards?).
Put it all together and powered it up. The W came up and it still looked odd. I then and moved the tv a little bit and heard the distinctive zzzz sound of a short circuit. Unplugged it and looked, could't find anything.
Plugged it back in and saw a spark coming from the left side inverter/driverboard. Unplugged it and opened up the cover to the untouched driver board to see if i could see anything. I then noticed that the high voltage power cable going to the CFL bulb was barely inserted. That is where the spark appeared to come from. I plugged everything back together and powered the tv back on. No zzzzz sound and everything seemed to be okay except now I get no picture. What did I do?
