How do i fix a non responsive tv set?


Do the ballast first. That should get the picture back. The main board controls everything else.

Replaced lamp on my Mitsubishi 82 in dlp. after 15 minutes pic started to flicker losing color. was advised to also change lamp ballast, did that but still flickers with new lamp. put old lamp back in tv...


When you put the old lamp back in did the picture look OK? If so why did you replace to begin with? Yes, there are some poorly manufactured lamps out there, where did you obtain the replacement? Was it true OEM?

Poor picture quality. Picture also tends to curve


The curving is caused by bad digital convergencr chips (2) located on large signal board. They need replaced along with blown pico fuses and the convergence resistors. Chips are huge compared to a regular IC. 2" x 1.5" and they will be bolted on fairly large heatsinks. Cloudy picture is most likely the coolant needs replaced in the picture tubes. This needs to be done approximately every 5 years.

Poor quality picture. specifically the red is brown and can't be adjusted. the tv is about 3 years old.


If the picture is replace the lamp. Lamp only affects brightness if the color is wacked replace the light engine.

I have sound, but no picture


I am finding a lot of people's lamps are going out. This maybe your problem too judging from what I have read above.

There are replacement lamps. They used to be pretty expensive but they are somewhat reasonable now. Below is a site you can order a new lamp this should fix the problem.

But before you order make sure that all the cables in the back of the television are in the right order. Red and White are audio while Yellow is video. A lot of people are unable to distinguish the yellow from the white.

If you have the other cables such as the blue and the black make sure the blue is with blue and black is with black. They are hard to see sometimes in a poorly lit area like behind a TV.

If everything is hooked up correctly.

Your next bet is the lamp replacement. Replacing the lamp its quite easy to do. Just remember to reset the TV lamp timer. Consulting your owners manual should help.

Here is the site for lamp replacements. You also can do your own search for lamp replacement.

Try cleaning mirror with a Lint free cloth with no other cleaning solution just dry lint free cloth. You should have Two access holes that you can pop out to get to mirror. Of course it will not be real easy to get to mirror if you do not have long arms but I have done it many times. Mirror sometimes get fogged causing poor reflection of mirror. This may help.
