Question about Flat Panel Televisions
TV is 7 months old....Push on/off button and Insignia emblem lights up blue...no sound or picture...turn set off and Insignia emblem turns red......I tried the hairdryer trick and nothing happened......I tried unplugging and holding the on button while plugging it up again.....nothing.....I've taken it apart and can't see anything burnt or broken.....Any help would be appreciated.
Heat the bridge rectifier with a blow dryer and see it turn right on.

If you are having just the LED go from Red to Blue (no picture no sound) more than likely you have a bad power supply. If you have any soldering skills you can fix it yourself. Replace all the 1000uf caps with new ones. Also replace the micro fuses soldered on the board near the caps. A electronic supply store can help you get the right parts. I did this and the set fired right back up.

It seems that this tv has a problem with a very short life span of the back light lamp of the LCD display, not sure why the sound doesn't work but it is related to the bulb being burnt out. The light is around $600.00 installed.

I have ns-lcd32 and it wouldn't turn on. No Backlight.
First, check the powers on the power supply.
There are 5V, 12V and 24V.
If they are OK, check the 24V on the Backlight Inverter Board.
You can check the input voltage which is 24V.
If it is there, check the fuses.
There are three fuses on the inverter board.
Two white fuses(surface mount) and one black fuse which has nunber 20.(20A).
Mine had bad 20A fuse. I replaced this fuse and it is working.

I have an Insignia HD30 tv and it will not turn on. I called Insignia main office and then Best Buy Service and spoke with 4 employees and a supervisor. All said the same thing; their tv's are made with a lamp that controls it coming on and it only last 2 or at best 3 yrs. It then has to be replaced. The service contract will only replace it one time. They do not tell you when you buy it and it is not in the manual. I am filing a complaint with the Attorney's General Office in my state, Comsumer Reports as this product contains a latent defect.

Same thing happening to me and mine is ONE day out of warranty and the customer service is like "too bad, it's not our problem anymore.." one even had the balls to say "I bet you wish it would have broken yesterday." I did a sarcastic laugh and said back "what I wish is that you guys would have made a TV that wasn't a piece of dog squeeze." I'm still arguing with customer-NO-service though, I'll let you know how i handled it.

I bought a 32' LCD TV made from insignia and it will not turn on. It was a 'open box item' now it is 15 months old- 3 months past warranty and it is completely finished. It's something to remember about Best Buy products. They are often pieces of junk. Isignia and Best Buy both have unavailable customer support, the local store transferred me from sales to Geek Squad- after Geek Squad said they don't do TV's I was transferred to a line I let ring for 2 minutes and the phone was never answered. I have been going to Best Buy instead of Circuit City but this has concerned me enough to not spend money at Best Buy anymore.
