GREY AREA ACROSS TOP OF MY HP 65' DLP PLEASE HELP

Sounds like a connection problem between board and DLP chip. The BGA connection which connects the DLP chip to the board, or the flex connector may be bad, causing the row and column section to not activate the micro-mirrors on the DLP chip. Not an easy fix. Regards.

Defective light tunnel :)

Sounds like dirty rollers or perhaps a bad print cartridge. If you have another ctg to replace try it first if lines are still there check the rollers inside the machine where the paper is fed. Use the sheet to match where the marks are to the rollers on the machine. When you find them clean with alcohol and let dry then try again. there are also paper feed tires that are inside the paper tray that could be dirty also.

Hope this helps

You will need to pull out the engine and check for any smudge on the lens. then proceed with the polarizers 3 of them they are sitting in front of the DLP chips, this is a delicates operation. the blue polarizer is the one which usually suffers burn-in (dark spots on the glass). if everything looks ok, then it means that the dlp chips are faulty, at that stage it will be uneconomical to be fixed.


Hope this helps!

I have made some posts on Fixya today, because my buddy and I fixed our rear projection tv in minutes and wanted to encourage others to do the same. Same thing happened to us and we went on line to find our it is the bulb. It wont just go at once but will radically degrade. Just go to dlp lamp replacement and they will get you a new one and walk you through it over the phone if need be.
