Lcd tv shuts down by its self

I have a magnavox 32mf231d lcd tv that shuts down after about 10 mins. If left alone it will restart by its self after a few seconds but only run for a couple of mins and then shut down again. If I unplug it for a few mins it will run for about 5 to 10 mins then shut down again. I placed a fan in the rear of the set and it runs a little longer before shutting down again. Is there anything I can do to fix this problem?

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.

Sanyo DP32640 LCD TV volume will suddenly spike to full, last 3-4 secs., shuts down, restarts at the original settings, holds 5-10 mins., repeats at 5-15 min. intervals

Set has a poltergeist in its main board where you have the setting electronics. Prices have dropped to such a point on this size set that it is simply not worth a repair.

Hello Kevin,

That type of issue is usually caused by bad filter capacitors on the power supply board. As the capacitors heat up they can't filter the output power correctly so the power supply shuts off to prevent damage. Here is a link to information and parts list of the capacitors neede3d to repair the power board.

My magnavox 32mf231d/37 tv will power up and the sound works, but the screen is blue... any help would be great!

Try taking it for a walk, or sing happy songs to it.
Depression is a common problem with today's LCD panels.
Most cases go untreated.
Talk to your doctor about receiving medication that may be able to help with it's symptoms. Side effects include nausea, diarrhea, genital warts, hemorrhoids, and an erection that lasts longer than 4 hours.
Do not watch your TV if yo are pregnant or using an MAOI, as these combinations have been known to cause permanent death.

Hold a flashlight up to the tv while the tv is on. If you see a picture your CFL is burnt out.

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.[email protected]/sets/72157611665895426/
