Question about Toshiba TP50H60 50" Rear Projection Television
White lines appear across the top of picture. Appears to be a heating problem as when floor fan placed in front of TV, lines disappear. Thank you.
Your symptom sounds like a faulty capacitor in the vertical deflection circuit.
What you are seeing is called vertical fold-over.
If you want to fix this yourself and are handy with a soldering iron, it is not that difficult. Just look for a 1uf capacitor near the vertical IC. The vertical IC will be a black IC with straight legs mounted to a heat sink, generally in the center of the circuit board.
Note: Be careful when working on a television as the CRT and other capacitors can hold a charge that can be very dangerous.
I would recommend that you contact a local service center and see if you can get a quote for the repair. I would normally charge between $120.00-130.00 for this type of repair. The cost may vary depending on where you are located.
I hope this information allows you to resolve this issue.
