The lamp has just been replaced and now the tv will only stay on for 30 minutes and then turn itself off. The lamp indicator light is red. We can turn the tv back on and the light goes off. Six months ago...


Did you press the System Reset button with a ball point pin on the front of the set? You might have a ballast going bad if it has never been replaced. But first, the reset button then you may have a thermal switch which is located just above the lamp housing. I test the thermal switches by unhooking (while set is unplugged) one of the wires and then putting an alligator clip jumper between the two wires to see if it last longer than the 30 minutes you mentioned. Lastly, there must not be any dust in and around the fan which can cause overheating. Sounds like you have an overheating problem initially. The thermal switch cuts the set off if there is overheating. And also if the switch is faulty it will cut off the set. Also look in the menu for a temperature setting if this model has a setting such as this.

I have a wd-73833 when i turn on the tv the front blue lights come on after a minute the tv turns itself off, there is no picture


I would check your lamp 1st. Do you have a lamp light flashing on the front of your set after TV shuts down? That is a message to let you know what might be wrong.

LAMP JUST WENT OUT


I have a 57" DLP and have replaced the bulb 3 times in 2&1/2 years. I'm not possitive but I think I have 6-800 hrs on it total. Mitsubishi claims it a part they expect to go out, but the told me they typically last about ten yrs. If you have proof of purchase they will send you a new one for free, otherwise it'll cost you about $150 on ebay.

TV shuts itself off after a couple minutes of being on.


One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.
