I brought my Insignia TV 32" only a year ago. The picture no longer comes on, only makes a clicking sound. Before the picture went away, the left side of the screen seem to have lost color or there was a shadow appearance to the left upper side of the screen.

Hi Chris,
Sounds like a popped capacitor......if you look inside again, try looking to see if any of the Capacitors are blown...

A 32" is worth a check out fee. I would suspect you have a vertical circuit problem which would not be real expensive.

you have defective flyback

most likely the power inverter, also suspect the p/s. best to have a trained tech check it. Julio at [email protected]

In about 90% of the time the power supply is defective if the TV fails to power ON.

Try to unplug the tv for a few seconds and then plug it back in again.

HI

I have a Insigna IS- TVHD30. It come on and have a perfect sound but I can't get a picture. Its about three years old. I went to sleep watching Tv. and when I woke up the t.V. was on, but wasn't showing a picture anymore. I decided to throw it away last week, and plugged it up and it came right for 2 days, it was perfect. Now it has went out a again. Can some help!!!

I would first try new cables, if not, then the board needs replacement.

Does anyone know where can I buy a screen for a 27" LCD Insignia TV. Model is NS-27LCD? My screen creaked. I checked out e-bay and have not found a broken TV with a good screen. Does anyone know where I can buy a screen at. 
Thank you all for you time.
