No picture The sound still works on the TV, but we have no picture. It is less than 3 years old, but not under warranty anymore. Any suggestions would be appreciated, or estimates on how much it would cost to get repaired. Thanks

How to repair an insignia 37" led tv

The first thing I would try is to disconnect the tv from the power source. Wait five minutes before plugging it back into the wall socket. Turn the tv back on and see if you get a display. Try changing the channel and switching inputs. See if you can get it to display anything at all. You could shine a flashlight at the screen and see if you can make out an image. If you see an image with a flashlight then your backlight is out.

Is your tv less than a year old? If it is less than a year old you are still under the manufacturer's warranty. I would see if Best Buy would honor the manufacturer's warranty in store. If that is not the case they should give you a number to contact Insignia directly.

If your tv is out of warranty, it may be cheaper to replace it. I would do your homework and check the price of a repair vs the price of a new tv.

Most likely the Li-Fi lamp is bad. If it is and your TV is less than 5 years old the lamp is covered under warranty by Panasonic but must be replaced by a Panasonic dealer. If its less than 2 years the labor is also covered. If its less than 5 years old and it appears the lamp isn't firing I would contact Panasonic to have a technician look it.

My TV is less than a year old. It has white

Do these lines disappear after the set warms up a little? If they don't then you most likely have bad buffer boards(X buffer or Y buffer). Sometimes it is also caused by a bad panel. Since your tv is less than 1 year old and is still under the 1year manufacturer warranty I strongly suggest that you contact the manufacturer for repairs.

If it is less than a year old than it is still under Warranty from LG. Their Customer Service Number is 1800-243-000. It sounds like to me it needs a Main Board to be replaced. Let LG help you get in touch with a Factory Service Facility to get you back up running again.
I hope this helps,

My lamp light is on my tv - I get sound n

If this is an LCD projection set and the "lamp" light is on the front, then the lamp needs to be changed. No, these are not covered under warranty. All of these lamps have lifetimes. The lamp has failed. Replace it being careful to completely close the access door. There are interlocks that prevent the set from working if the door is not completely closed.

Tv turns it self off after only 2-3 seconds and makes crack noise

Since the set is less than 1 year old, it should still be under warranty. Request warranty service.

The noise you are hearing is probably arcing inside the set on the power supply board. Continuing to attempt to turn on the set will only make things worse. Please request warranty service as this is unusual for a TV that new.

It's the 26 inch version but have problem with picture

Hi Paul,
It looks like your TV might have a main board failure if the screen stays white without video. Since your TV is less then a year, I would suggest to contact the manufacturers to get fix under warranty. Most electronics devices carry one year warranty.
Good Luck.

Blown Picture

There is not much you can do to fix your plasma. Since the plasma is less then 1 year old, still under Samsung warranty.
I would suggest to call them to fix it.
Good luck.
