TV shuts down

My HP m6580n shuts down after 1-3 hours. No warning lights or error message. TV flickers a little before shutting down. Picture looks great otherwise.

Re: TV shuts down

In response to the "Guest" post on 12/21/07, first, thanks for your reply. Yes, I agree that it's potentially a thermal issue, given that the longer it's on, the more often it happens. However, I have never gotten temperature warning lights to come on in relation to this issue. (Maybe the temperature sensor is broken.) I have a new bulb coming tomorrow, so I can see if that fixes things. If not, the next thing will be for me to pull off the back panel and vaccuum everything out to see if the heat sinks have gotten dirty (and therefore, less effective).

HP said they would allow me to return the bulb within 21 days, so it doesn't cost me anything to try the new bulb.

I'll put up another post with my results later.

Re: TV shuts down

Stating the obvious, I suppose, but it may be possible that the TV is simply overheating. These giant TVs create a LOT of heat. Perhaps removing it from your current TV cabinet and setting it on a stand outside will help. You may even want to try a small fan to blow air to the back of the machine to see if this fixes the issue.

If so, and it's under warranty, I'd have a tech look at it. May be replacement parts that won't run as hot.

Sound but no video

Sound like you have a faulty inverter. The next time the picture turns off, turn off the lights in the room. Take a bright flashlight and shine it on the screen. If you still see a faint picture, more than likely you have a fault with the inverter.

Sharp lc-32d4uj picture flickers, then turns off. have to push system reset and plug back in to see pic again for only 2 minutes tops

if the picture flickers, then after a while turns off the cause will be the inverter board or the back light. the processor detect an error so the main board will will shut down. you must need to check a dry joints connector at the inverter board and then bad component like high voltage transformer or shorted diodes. hope this can help good luck, by the way if you think you can not do the job with your own just leave it to the trained technician, at least you have an idea what to expect when you decide to hire for somebody to fix the tv.

Your tv timer might be set for it to shut down every hours. If you canot change it try a factory reset of your tv. If that does not help then you might have a bad signal board.

Sony LCD 52 inch

This sound like you are having problems with the power supply board. Since you are getting a momentary picture and sound the fuses are good but TVs today have "shorts" and "overvoltage" circuitry build in that will shut it down on errors. Someone knowledgeable in electronics will have to isolate the exact cause.
