Question about Proscan PS56670 56" Rear Projection Television

1 Answer

Shrunken picture I purchased this used (came with the house) 6 months ago. TV picture went from full screen to about 6 inches top to bottom, in a concave type shape on the bottom quarter of the screen. sound, remote, etc. seem to be working fine- just a picture that seems to cram about 40 inches of verticle picture into about 6 inches.

You can try doing this, turn on the Tv and select the service menu, if that tint also shows on the menu, it's most probable to be your DMD board, but if it doesn't it might be the video board..

From what you're describing your focus block is probably failing JVC p/n#129P059050. It's probably also very vibration sensitive. They're about $80.00 dollars and they are also interchangeable with the Mitsubishi focus pack p/n#920p016010. Not a difficult repair - we do about 5-6 a month. Real easy in-home repair. Hope this helps. Bill
