It sounds more like the tuner is drifting or a dry solder joint on a power supply.

If the television is more than 5 years old it is cheaper to get a new one than pay for someone to sit for a couple of hours with a soldering iron.

If you decide to try a do it yourself approach be careful as there are mains voltage components inside and in older sets a device called a tripler which can give you a nasty belt

Hi.
The lamp does not cause flickering or halos. If picture colors are not matching, you may get a kind of halo, in that case the convergence ICs must be replaced, that is a common fault on rear projection and crt tvs.
Th#e fault depends on the TV model, if TV is an LCD for example, it will be a defective LCD controller board.

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?

Lamp light blinking red


From your description it sounds like the lamp bulbs needs to be replaced.
You need one of these:
http://www.amazon.com/Hitachi-50VS69-Watt-RPTV-Replacement/dp/B006C58MOI
NOTE: DO NOT TOUCH THE GLASS PART OF THIS BULB. The smudges from your fingers can show up on the image projected onto your screen and make things look blurry.
Once you have the new bulb then turn off the TV and unplug it. On the back panel there is a rectangle on the left with a screw holding it on. Use a philips head screwdriver to loosen the screw then slide the rectangular panel to the left and pull it off. Inside will be the old lamp bulb. Use the screw driver again to remove the screw holding the lamp bulb in and pull the lamp bulb out (it may be hot). Insert the new bulb and then screw it back in. Place the panel back on and screw it back in as well. Make sure the screws are tight or the TV may not turn on. You can now plug the TV back in and turn it on. If done correctly this should resolve the issue.

I bought a new lamp for my television and it


It is not the lamp, it is the balister that over heats. Defect in the TV. Go to or call consumer affairs and file a complaint as this should not happen.

Screen is fine when I first turn on TV, then goes black


Sounds like you dlp lamp is going out. That's a pretty old TV and if you are still running on the stock lamp this is exactly the type of thing that will happen. The lamp model for this particular tv is the ty-la1001. You can find that over here:

Does ur camera ever say "lens error"? It sounds like what I typically hear as a lens error and the only way to fix that is to send it into repairs.
