Our 37" in the past

Our 37" TV; in the past couple of months has decided just turn off. It can be turned back on but may go right back off immediately or several minutes or hours.

    We are having the same problem. The power goes off (green light to yellow) and can be turned back on but goes off again. Not always and not always the same interval. Can be minutes or hours, sometimes goes off several times an hour.

It sounds like the main power supply board. If you can hear the relay click but no other response from the TV, it would be a good bet to start there.

I just replied to a similar problem on the same model TV. If the relay contacts are no good or if there is poor soldering on the main board, you'll get this symptom. Although a bad set of relay contacts aren't out of the question, I think it's more likely that there are cold solder joints on the board. If this is a relatively new TV and used to work fine, the thermal cycling when the TV was operating might have been enough to cause intermittent contact with the solder joints. If you're up to it, consider resoldering the main board especially near the relay section. Let me know what happens. Please rate accordingly.

Hello, This is a problem with the switching transformer or the ballast used to fire the backlight. You will have to replace the ballast and or the switching transformer soon. In order to replace these items, I would suggest taking it to a qualified TV technician for servicing. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

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.

Philips 42PF9956/37 Plasma TV - Looking for y sustain board


it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.
