How do I remove vertical lines from my Mitsubishi 65 inch DLP?

The white spots are pixels that are burned out. They will just gradually get worse. You will need a new screen or just replace the whole TV. Probably buy a new one for what it will cost to get a new screen put in it.

i had the same lines on my 65' mitsubishi tv after replacing the DLP chip. after going back over everything i realized that the casinf that holds the chip in was not in the lock position. i took the chip out and replaced it then turned the little locking mechanism to the locked position. now my screen is perfect. hope this helps.

This is the reason I do not nor will our shop do this, considering cost of engine rebuild versus this not worth the trouble---only thing I can suggest is go over all you did to make sure no bad connection etc.

had white dots on mine as well i changed the dlp chip and put it back together and got the white vertical lines i decided to check all connections and make sure the chip was locked in correctly
it was not locked in securely i reassembled and now problem solved picture looks brand new so always check connections before assuming its the dmd board

normally white spots are whithin the screen. it is also called "panel". it is the most costly part in the tv. but one need to inspect the tv first before making sure it need to be replace. try to disconnect all cables inside the tv by opening the back cover & fix them again.

Hi,all HDTV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board and also white spots.

A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens.

The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them.

Good luck.

Hi, I have a mitsubishi 65" DLP model # 65733 that I bought in December 2007 brand new, about six months ago I started spoting white dots on my screen that started blinking and then became permanent, thinking is was dust I cleaned everything inside with compressed air without success.
The stars multiply daily to a point that it was intolerable to watch anything with all the white stars and a few black ones that showed up.
We called mitsubishi but got no where, I was out of warranty. (they still deny having a problem with their DLP's)

I had a service tech inspect the tv and was told it could run about $800 to $1000 to replace the light engine with refurbished parts with 90 day warranties.

Researching on line I came across a DLP chip that is compatible with several mitsubishi and samsung models, so I decided to chance it, and replace just the DMD chip before we trash the tv, it was unthinkable to pay $800 to repair a tv that we could buy now for under $900.
Thanks God the "gamble" paid out and the problem got solve with just $150 DLP chip in about 15 minutes of my time.
If you are not mechanically nor electronically inclined, I recommend you use a technician for the installation, but don't let anyone tell you you need to replace the whole light engine, it is a ripoff.
If your problem is just white or black dots on the screen that do not move.......this will solve your problem!!

P.S. Hope this will help you and for the record..... "I will never buy a mitsubishi product again".

This problems very exspensive to fix.The Light projection Engine have a problems,with a IC design flaw.This problems happen to many Big screen tvs 65 and up have a design IC flaw by many companies like Sony,Mitsubishi,Toshiba and Samsang.Call up Mitsubishi make some kind of deal with them to help u to fix the Light projection Engine by replacing the IC or replace the whole entire Light projection Egine.

If you get White or black dots all over the screen (DMD symptom)
If you get a pixilated picture (DMD Board)

If you bought the set new you might just want to contact the manufacturer - if they are decent, they might just try to help you out with your dilemma.
