What you are describing is a DLP chip failure. Probably the chip, remote possibility it's the screws that compress the chip down on the formatter board. The possibility of the compression screws enter into the equation with the install of the new lamp. New thermal loading on the socket assy. Regardless of warranty, Contact MFG. The devices rarely go bad.

Hi there

This would mean that your Projector is still under warranty.

The problem you are describing is a faulty Mainboard - which fortunatelly for you is covered under warranty.

You most likely have a bad address board or the conntection is dirty between the address board and the PD (Plasma Display Panel). This is not a do it yourself repair as any damage to the cables to the PDP would require a PDP replacement.

Verticle lines on screen


This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
