Our TV shuts off inertmittenly

Our heater cuts off after 2 mins or less and it shoe 90 on the temps diplay. Had it for a couple of years. It's been vacuum and clean and still the same results. I don't have the schematic or the owners manual..

Hi,
Please check and fix your defective capacitor on power supply circuit.

Well if your tv is older like the one in the pic it sounds like the bulb is overheating, you may want to vacuum the dust out of the back and make sure it isn't got block of air flow in the back and also make sure it isn't up against a heat source

Hello,

Sound like you have a overheating problem. Your capacitors might have reached their end of life thus making them overheat quickly. Try to check if there is a fan inside your TV. If there is a fan, try to clean it see if that helps.

I hope this helps. Have a nice day.

Im not sure what brand you are inquiring about. My Hitachi 50v715 DLP did the same thing and it turned out to be the Lamp was going out. I bought a new original hitachi lamp(phillips) and put it in and it works great. So if your lamp has not been changed out in a couple of years then its probably time. Hope this is helpful.

Do you have enough air flow to cool it?
It may be overheating....add a fan blowing into it and see if that keeps it on.If it does put a strong small computer fan in somewhere to keep it cool.

i had the same problem with my set shutting off and was told it may be the ballast so i changed that but it still would start up and shut down after a few mins, then i was asked if the bulb had been changed and i had not, so i did change the bulb and have not had it shut down yet. :) (so try a new bulb)

All you need to do is remove the back cover, then remove the metal cover that covered the power supply. Watch tv w/o cover, it won't shut down again. Try it and post here if it works.
