Insignia LCD TV loses power

I have an Insignia model NS-LCD37 TV (13 mos old) that loses power intermittently. Both picture and sound cut off and then come back on after a minute. The set is connected to a cable box, but our other television is not having an issue so I've ruled out satellite problems.

I heard that there are power issues with Insignias that can sometimes be repaired by installing new capacitors?

There might be faulty capacitors that are causing the intermittent power up/down. Check the 2200uF(2 per board) capacitors for bulging conditions or you can replace the entire assembly.
Let me know if you need further assistance.

Probably it is a faulty power board.

    If it loses power intermittently, and completely (it turns off) then It is probably a faulty power board, if it stays on and loses audio and sound, then it means that some other board is faulty, probably a chip on the main board.
    Also a bad connector cable can cause the problem.
    The TV must be taken apart and inspected by a technician.
    If you need support, or you want to check your warranty status or buy an extended warranty, you can call the phone number listed on the owner manual.

My Insignia TV model: ns-lcd26-09 starts flickering intermittently for a while after watching, quits after 20 minutes, then starts again.


Definitely sounds like a bad power supply. Especially if it's making any buzzing/hissing noises while it's flickering.
All Insignia products carry a two year manufactures warranty, which Best Buy will gladly service for you. If you're out of warranty, here is a link to a replacement part:

Your probably having what cable guys call a SNR ( signal to noise ) issue. There's no way to know unless you call your cable provider. The SNR should be 32 and above with zero pre/post errors. In case you want to ask the tech what they are.

NS-LCD42HD-09 Insignia. The power light is on, but no sound, no picture. TV is 13mths old. Best Buy junk I'm guessing, but as a electrical engineer, I'm determined to fix it myself. I think it's the power...


At least the 5VDC stand by power supply is working, there will be a control signal pin from the mainboard to the power supply board to turn on the rest of the power supplies (24vdc for the back light inverter boards, 12vdc for other circuits). Any bulging caps in the power supply?
