The dark or black picture is caused by a failure in the back light power supply. The problem can be corrected by replacing a few parts called capacitors on the board. Replacing them will require a little soldering but anyone can do it. Here is a link to a page that shows what needs to be replaced.

Proview 19# model PL926Wbi


thers Sounds like the problem I'm having /had exactly. When I opened the case I found that like others the 470mf capacitors on the power board had gone bad. (See the post from Delphiuser)

The capacitors are probably from a Chinese company called Xandu and I'm currently looking for a replacement capacitor to fit the circuit. Its a 470 mf cap with a 25 volt rating .
