Why does my DLP 60 inch Mitsubishi TV keep turning off and flashing a red light?
I recently replaced my dlp chip in order to fix little white dots. It fixed dots issue, and the TV worked perfectly for a couple of days. However, I wake up one morning, turn the tv on, hear a slight click, and now I have a flickering of the red light. I consulted a repair expert and he informed me that it was my lamp. I just replaced this lamp a little over a year ago and I have warranty. I took the lamp out, and the lamp is not damaged and is actually in great shape. I put the lamp back in, closed the little door, and the tv works fine. However, I have to repeat this process every 2 days, as the tv continues to go out and the red light flashes. I consulted the repair tech once again, and he's informing me that there may be a bad connection. I'm willing to take out the entire light engine, motherboard, where have you...I just really want to fix my Tv. It is a great Tv and I love it.

Re: Why does my DLP 60 inch Mitsubishi TV keep turning...
Your repair tech hinted correct. Although the bad connection will likely be in the power supply, it actualy can sit everywhere the power goes. Can be anordinary plug / connector with a little oxidatin, or a dab soldering point. Or perhaps a electrolitic cap, slowely dying.
Let the tech do his job. He has the tools, education and skills to keep your beloved TV alive.

You will need the DLP chip replaced. I do not recommend trying this on your own on a Mitsubishi. You need a technician who has extensive Mitsubishi experience to replace that chip(if it is available for your particular model) If the chip is not available for your particular model, it means replacing the light engine.For that cost I would update to a LCD or LED TV & come out ahead.
If you want an idea what it costs to replace the DLP chip (if avail for your unit) contact a local servicer & see what they can quote you over the phone. Be sure you are sitting down.
Considering the age of your unit I would be looking at an LCD or LED flat screen.
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.
White dots on your RPTV television are the result of the DLP chip being worn out. You can replace it very easily by buying a new DLP chip for just under $190 and installing the new chip. There is a very good forum over at fixyourDLP that offers tutorials for replacing the DLP. http://www.fixyourdlp.com/2012/10/11/banish-white-dots-from-the-samsung-hl56a650c1-with-a-new-4719-001997-dlp-chip/ or for Mitsubishi http://www.fixyourdlp.com/2012/10/02/install-a-new-4719-001997-dlp-chip-and-banish-white-dots-on-the-mitsubishi-wd-82737/
Your problem is that the DMD device is failing. You're in luck, though. Mitubishi has recently released a replacement DMD device in order to keep repair costs down for the consumer. Take your TV to an authorized Mitsubishi servicer for repairs.
Your TV is DLP projection TV. DLP is Digital Light Processing. Digitally processed light coming out of DMD (Digital Micro mirror Device) is projected on the TV screen. This DMD is made of thousands of tiny mirrors & the size is about 0.7 inch. These mirrors are fixed with tiny hinges for its movement. They reflect light as per processed signal. DLP is invented by Texas Instruments. When there are dots on the screen, that means the tiny mirrors representing the dots are stuck in its position. If the dots are few & the viewing is bearable, just leave as it is. If the dots are more than bearable then you will have replace the DMD chip which is quite costly.
Mitsubishi that the one,who u should contact.Talk to them make some kind of deal with them to help u to do a repairing or replace the tv Light Engine Projection Block.That the tv problems,this problems a design flaw on the tv Light Projection Egine Block the IC they put in that causes of this white spots are showing up will continue showing up more and more white dots.It will not stops.
This problems is the tv Projection Light Engine design flaw with it IC chip.These problems happen to many models of it DLP tvs Big Screen 60 and up.Mitsubishi,Samsung,Sony,Toshiba all used the same IC chip on their 60 and up on their DLP tvs Big Screen.Tries make deal with Mitsubishi help u split the cost of repair the tv Projection Light Engine by replacing the IC chip or replaced the entire Projection Light Engine system.This problems is not new,been going on for a few years.Many people when on Youtube **** about this problems with white dots showing up on their tvs screens and multiplying rapidly.
The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments to rate my answer...Thanks..
