There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

32" flat screen Westinghouse TV


Hello, it sounds like you need to replace the inverter board on this unit. I would recommend opening the unit from the back cover, get the part # for the inverter board (long green board normally running accross the edge of the TV) and go to www.shopjimmy.com, they should have it in stock and if not you can try www.invertercentral.com, they should also have it.

Westinghouse 27" lcd hdtv


My Wesinghouse 27" lcd hdtv jumps and vertical hold is out of control after being on 15 mins. The cable company checked the connection and it is clean. We did not damage the tv. It has been doing this since we got it. We did not get a service contract. Sometimes the screen goes black with a small rolling picture on top. Help me please. Can the maufacter still help us?
we lost all the papers when we moved.

Have you tried unplugging overnight? Sometimes mine gets screen garbage and that clears it up. Of course, now it says "Auto Scan Required" every time I power up. Maybe I should've grabbed that after Xmas 32" at Fry's for $400.
