I have a 25" Model #DS25390 SDTV Sanyo tv with white lines going across the top portion of my tv screen. I bought the tv for $25 to put in the basement so I don't want to spend alot of money on it. If anybody knows a simple and cheap way of fixing the problem I would be greatly appreciative.
Thanks in advance!

I think the problem is due to the vertical output coupling capacitor is failing,
causing a fold at the top of the picture.these are white 'retrace lines'
visible as a result of the fold.
The repair require replacement of the capacitor by a qualified tech.
Screen voltage has also gone up to high. I suggest you to check solder connects around flyback.
This is a website of a technician service www.tvrepairjacksonvillefl.com , you can get more details for the solution and know the repair price.
