I have the Sony VPL CS1 projektor and want to connect it to my tv, so that i can watch television channels on the big projektor screen, is this possible?

I think you want something that has nothing to do with digit cameras. Perhaps you are better served in the correct category?
I can tell you lots of things about digital cameras and their lenses, but here I must pass.

change resolution down on the source (1024x768 should work)

hi,
check the lamp cover is it open or not. there is switch for sensing, is the lamp cover is open or not. may be it became faulty. also check the lamp is it burned or not . if found burned replace it.
ok

first of all open the projector and clean it form a bursh then cheack a losing if stips and jumpers thats it

overheated or lamp is past it's time. you may need to change the lamp, replace the lamp timer. while you're in there, clean it out.

Have you replaced its Lamp?

I had the same problem with a Sony VPL CS1. It's not the mainboard, but the blue filter - cost to repair runs around $500 US.
Hope that helps.

Hi there

You should first check if there is any visible damage on your lamp. If not then it could be a faulty Ballast ( lamp powersupply )

A warning in the manual was given as to be carefull when using this projector with games as some parts of the screen will not move, just like if you watch Tv on it and there is a channel logo in one corner that doesn't move! It burns the display like it would on a pc monitor if no screen saver set. This is not a problem you can fix, that is perminant damage to the lcd in the projector!! S Platt

Hi Tim

I've seen this many times. Only way to get rid of it is to replace the Mainboard.

This will get worse as time goes by.
