TV was shutting off every 30 min.

My 2007 Tahoe does the same thing but service traction control comes on then goes into limp mode which you can only drive a max of 5mph i then shut it down start it 2 mins later all is well...I took the air intake off leading into the throttle body and cleaned the throttle body around the butterfly valve and had no problems for 2 months then started again so im thinking the feul filter needs replaced more often than recommended..Thats where im at with this mess right now im gonna clean it again and replace the feul filter and the gas cap and see what kinda results i get...Will update my post with the results from the cleaning and reolacements

Sounds like the power supply is overheating.

Wow! Yours is the best description of a problem I have ever seen!!! Before I read the whole thing I figured you missed the pressure check as most people do but you nailed it. This is what I would try, Replace the air filter, the fuel filter, and the fuel (to make absolutely sure there is no water in the fuel) and readjust the fuel/air mixture. If that does not do it replace the cadmium cell they only cost pennies. Let me know how you make out and good luck.

PS, I have one of these so I am pretty familiar with the problems.

The thought is that it needs to be either cleaned out. Dust build up in it's air intake filter or you probably need another new lamp. Usually when these set's shut themselves down is because they are overheating or they can't maintain the voltage to keep the lamp lit.

Good chance that the idle Air Control (IAC) valve is dirty with carbon and needs to be cleaned. You can clean it by cleaning the in side of the throttle body with Throttle body cleaner (follow the instructions on the can), you can pick up a can at any parts store like Auto Zone. Disconnect the air intake tube from the Throttle body and spray the cleaner throughout the throttle body, make sue your clean the throttle blade and IAC passage way. Once your done with cleaning the throttle body and IAC passage way, just make sure you spray enough through the IAC passage way to ensure you get the IAC cleaned also. Once everything is cleaned, put everything back together and turn the ignition to the run position for 30 seconds and then turn it off for 10 seconds and then start the car, this will reset the IAC and if there is lots of smoke coming from the tail pipe. That.s normal, it's just residual cleaner and carbon burning off and will take no more then 10 min. This should clear up the problem, but check the wire leads to the IAC on the side of the throttle body for any damages like corrosion and after cleaning the IAC problem is still there. The IAC will need to be replaced, but i don't think so, since you did not mentioned any check engine lights on. Good luck and keep me posted, be glad to know your car is running 100% again soon.

Sounds like two problems. Not enough combustion air or a defective high temperature limit switch. You enclosure may not be getting enough outside air to properly sustain combustion. If the unit has a rollout thermostat it may be defective and stopping everything.

replace the lamp. . thats all . and make sure to put the lamp door back on of course.

Is your air intake clean or clogged.. Maybe it's overheating causing it to shut off.. Had the same problem didn't replace the bulb but cleaned the intake and it works great again. Worth a try.. Intake is located on the left back pannel of the tv.. outside pannel pops off easly.

The motor overheats from the filter being clogged underneath the canister or the canister or both are clogged-without the air flow the motor overheats and shuts off as a precautionary measure.By letting the motor cool off it will start again but will turn off shortly if the filters are not properly cleaned.Hope this helps everyone.

TRY REPLACING THE BALLAST POWER SUPPLY FOR THE LAMP-THIS WILL HAVE TO BE CHECKED FIRST BY A SERVICE TECH TO VERIFY WHETHER THE LAMP DRIVE VOLTAGE IS SUFFICENT. IF NOT SUSPECT A BAD BALLAST POWER SUPPLY. ALSO COULD JUST A DEFECTIVE LAMP. AAA ELEC
