Very common power supply failure. These power supply's have cheaper made capacitor's in them that wear out and overheat quickly. They are not too awfully expensive to replace.

hmmm...when the remote was bumped, as in stepped on, perhaps? or dropped? the tv itself would be unlikely to be affected in the manner in which you mention, due to this.

TV popped very loud, then a green light blinked off and on. Then the red light (lamp) blinked off and on. Then the TV reset itself


I'm confused. Is the TV still working or not?
Pops can come from the CRT's tubes themselves. If a large enough pop then it may be that the CRT has imploded. When this happens the TV usually doesn't turn itself on again or is able to be powered back on.
Sony is a very servicable TV. They have carried parts for over 10 years. A good Sony Repair shop can fix it.

I get a pop up sign on my set that states..."The system is experiencing above normal temperatures. Unless corrected it will shot itself off..." The TV is next to an A/C vent. I have it off for 8-12 hours...


This seems it could be a temperature issue either the temperature sensor is malfunctioning or the cooling fans aren't spinning at the right speed or not spinning at all. It would be best if you check the owners manual and look for the system reset feature, this may work, or the other option would be to hit the reset button.

Insignia lcd 37''powering off and right back on by itself!


Hi Ed,
Since the TV is less then a year old and still under manufacturers warranty, I would suggest to take back to the vendor to get it fix because this LCD behavior is not going to get any better.
The failure on this TV is related to a power supply in most cases if the TV is turning OFF by itself or needs to be unplug to let cooldown and it works afterward.

Audio Menu keeps popping up


There are probably some failing components in the uPC control area, or with the keypad board on the TV sets front panel. It is also possible that there is a problem with the filtering of the distributed power through the circuit boards of the set, and there is some noise causing a false trigger of the function.

This type of fault can take some time for the tech to figure out, unless it is a published common fault with the particular model of set where they give a list of parts to change.

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer
