Question about Televison & Video
I have a 21" Sharp TV that is 3-4 years old or maybe even more. At random times throwout the day, the picture disappears and is replaced by a bright white horizontal line across the screen. If I turn the TV off for a count of 5 or so and turn it back on, the line disappears. Sometimes it comes back after a minute or so and sometimes it doesn't. I have not been able to determine whether this is due to circuit overloads or power surges or what. Is this worth repairing or should I just trash it and get a new one? I have A 26" sharp I don't know the model but the same thing happens to mine.
Please check cold solder joints in main board, specially in vertical deflection area. Its problem of dry solder joints. Little solder work required to fix this problem.
