First easy thing to try is unplug the TV from the power for about half an hour and try it again. If no luck; Do you get the same effect if you unplug the cable box from the tv completely? what about if you are watching something from another source - DVD player or VHS or PC or similar. Do you get the same? Could you post back a photo of the green dots etc? may help us to diagnose the problem. Do you have a model number for your set - it doesn't seem to have posted? awaiting your info :)

My ViewSonic PJD6221 Projector shows scattered white dots on the screen


Your dlp chip is going bad and cannot be fixed economically. Several of the mirrors on the chip are hanging up and they won't come back. It will just get worse. My Sharp XR32X is doing the same thing. New projector time.

Your random access memory (RAM) is faulty or badly connected. Unscrew and open the cover at the bottom of the laptop, pull two latches to the side and the ram module will tilt upwards. Remove it from the connector, wipe the connecting plates of the ram with rubber to get them shine and install back. If the problem persist, use hiren boot cd, start the GoldMem program to test the ram. If faulty, replce it. If the probem persist again then motherboard is faulty and needs replacement.

Black lines 1/8 of an inch apart going down my screen when playin


I had this happen a few times, then after a while it stoped working all together. In the end I was getting the E74 message code appear when I turned on my xbox 360.

You'll probley get this happen with yours soon, the E74 code means theres a problem with your visual display.

Sometimes it can be as simple as changing your HD Lead or scart lead, whatever your using. If you know someone else with a xbox try theirs.

If this doesn't work you'll have to send it off to mircosoft, it will be free if your still under warrenty, if not I think it's about £100+

Or you could go on www.cd24-7.co.uk and buy one of their DIY kits.

Hope this helps.
