I have a Sanyo DP46484 about one and one half years old. A few days ago a series of black lines appered at the top of the screen about 6 inches down from the top. The total width of the lines is about one inch and start at the left hand side of the screen and continue across about 3/4s of the screen where they fade away. This is not just one line but aproximitly 9 lines consisting of 1 bold line in middle and 4 smaller lines above it and 5 below it. Can someone point me in the right direction?

Hello williskathy2,

This might be a problem with the circuitry of the screen driver. what happens is the one of the drivers in the display matrix IC goes bad and it can not fire that one string of LCD elements, and this creates the line that you see. Since the line is pink, I would say that the driver is incorrectly firing the string of LCD elements. I would suggest that if you have a background in electronics you check the voltage levels on the display driver IC and the connection to the screen. If you do not have a background in electronics I would suggest that you have a qualified TV technician fix your problem.

I hope this helps,

More than likely your control board. Available at www.partstore.com Cost could be between $130 and $200. Not that complicated to install if you can use a screwdriver and are careful. Let me know how this works out.

I'm having the same problem with the same TV. I called around to repair shops and I guess it's fixable. Haven't taken it in yet but I was told it most likely is a bad module. But this seems to be a really common problem with this television
