Sanyo 32inch
Model DP32647

I posted this question in another forum so ill just copy and paste it.

I have a sanyo 32 inch, model DP32647, had it for 2-3 years now.

It works perfectly except after prolonged use it begins to flicker white lines on the screen and cant watch or play games on it. At first works fine later on you can notice that a little section from left to right a small inch or so is kinda lighter than the other areas then it escalates longer the tv is on, other areas and then bigger areas until most of the screen is flickering it in different places but not in unison. Oh and i dont think its the connection, Checked it, even tried to turn it to an input that doesnt have anything connected to it and the black screen still white lines show up.

If i turn it off for a 10 seconds, unlpug for 1 minute to reset it, then turn it on its fine once again but then it goes down hill after its been on for a while. I have no idea whats up with this.

I uploaded the tv messing up on youtube, link below. Even changed to other inputs that werent plugged in and still showed the lines and all.

Thank you for you're time and help.

I have never fixed or opened a tv before so please be specific on what to look for or what to fix. Ah if i cant fix it on my own please tell me the average $ to fix this.

Please respond, I am a bit desperate so any help is appreciated, Once again thank you for you're time in helping me.

Any "puffed" lytics?
How are power supply voltages? Any ripple?

What visible signs show that the caps are bad?

Not all caps show visible signs of failure even though they may be still performing below the required specs. The ones which do can be bulged at the top of the cap (it is supposed to be flat. The vents at the top of the cap could also be obviously split open in extreme cases. There may be a brown/orange/yellow discharge which can be very small in the center of the top of the cap. It can also be a larger quantity all over the top of the cap. The bottom of the caps may not be flat on the board because there is swelling there. The bung at the bottom of the cap may have been pushed out and the cap is making a discharge on the motherboard which may have dried on the board.
