I had the same problems that most of you have been having, tv turning on and off, lights flashing in all different colors, having to unplug tv to reset and all of that good stuff. I noticed that most of the time this would happen once the tv would start to heat up, and I could hear the fan working a little harder. Well I am not an electrician but It was very simple to unscrew the lower bottom park of the tv, where the fan and most of the electronics sit, then I used an oxygen tank ( I work for a medical company ) to blow out all the dust in the tv, ( you can olso use the compressed air use for computer, but if grandma or grampa have some O2 laying around, it works really good, LOL. )and was very surpriced to see how dusty it was, then I removed the MAIN FAN ( you only need to remove three screws, however there's a box in fron of it, which you'll have to remove first in order to get to the fan ). this may sound a little complicated, but trust me it is not, once you have taken the fan off, clean it all the way around ( best to use a clean rag, the compressed air was not doing the job.
long story short, once I cleaned the fan and put it all back together. The TV still didn't work LOL, Just kidding, It has been working perfect for a little over a week.
If I can help in any other way, please e-mail me @ [email protected]
hope this helps.

This all probably comes a couple years too late, but when you
install a new lamp, you’ll want to reset the hours on the counter your
television has. Doing this will allow you to avoid getting any
messages about the lamp needing to be replaced despite you having a new
lamp inside your set.
If you need to get into the service menu, you can do so by following these directions:
With power on, hold down VOL minus button on projection display and hold down the PIP or SPLIT button (try both) on the remote simultaneously for more than 5 seconds.

I have similar problems. I removed the back panel and use compressed air to blow out all the dust from all the components. Just remember not to blow into the main fan on the right as that is the one cooling the lamp. I don't know for sure if this is the only problem.
Dust built up caused heat built up on the components.

I have the same exact problem. I opened the back panel and used compressed air to blow out all the dust inside. Be careful not to blow into the fan on the right as that will get the dust inside the lamp module. Use a vacuum hose to clean out the dust from all around. This helps a bit. The unit will only turn off after a few hours of use rather than every 5 10 minutes.
I am surprised you still have the original lamp. It is only rated for 10,000 hours.

SOURCE: projection lamp timer reset
The others are almost right. You first hold down the minus button on your "TV", then at the same time hold down 0 on your remote. Make sure if you have a universal remote to swich it to TV.
