We have no sound on a old style tv (not lcd flat screen) picture is fine its a 28inch bought new 3 years ago

Is it a perfect square like there is a box on the screen ? if so it could be an easy fix if not then time for a new TV!! Did it just slowy get worse or was it just like that one day?

Hello
The power supply regulator board to your set has the fault. If you try to open the set, or try to repair it by yourself, the warranty will void. The set must have warranty as it is new. Why do you spend for it? Just contact the nearest authorised service center for Sceptre. the components in this set will be very hard to get from open electronic spare part market, and will costly too.

Tv is less than a year old call Phillips for warrenty repair.This tv have a 1 or 2 long boards,call the LCD inverter boards,it have problems,about to died.These 1 or 2 long LCD inverter boards are to help the LCD screen to have a backlight to produced a picture.That why u have dead pictures,but still have sound.Tries websites like Shopjimmy.com,Ebay.com to buy those 1 or 2 long LCD inverter boards for the replacement.

I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.

Typically if you have a backlight and no video image it's going to be the T-Con board. We do know it's most likely not the powersupply board because the back light comes on. Could also possibly be the main board, but typically the T-con boards are cheaper and I'd say you got a 70% chance that's the issue. Good luck.

Hi, I have the exact same problem. I was wondering if you could tell me how you fixed it? Mine is only 2 hours old from the box

Most high voltage electronic parts in a tube style television only have a life of 1-3 years. All of your internal parts are due to burn out or fail.

I would give up and sell/give away this tv and buy a new LCD or Plasma version. Repairing and old tube style tv is probably going to cost over 500 dollars. Just put that money to a nice new one instead. I know it sucks to say goodbuy to your old friend, but the era of the tube tv has ended.

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.

The short answer is yep!! The longer answer will require that you post the model number. With that in hand I should be able to provide you with some detailed possibilities.

Thanks,
Dan

So, where are the answers?
