Question about Flat Panel Televisions

2 Answers

I have a Poloroid LCD flat screen, 42", bought it at Walmart 13 months ago. around 2 months ago the picture stopped staying, the screen goes to black. We have sound but no picture. we were re-booting and getting it to come back, but now we turn on and hear a little pop and the screen never comes up. We see the log0 and then goes black. Any suggestions?

Hi pdooley1, I will be happy to help, We need to check the backlight, the easiest way to do this is, 

  1. Turn tv on to a point you have sound.
  2. Take a flashlight or a lamp with a bare bulb and shine it on the screen.
  3. Look very closely at the screen and see if you see a dark video image.
If you can see an image you have a bad backlight inverter. let me know what you find and I can assist with replacement. Please rate this solution. lone99star

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.

My flat screen Poloroid TV went black, it hissed and cloud of gas or smoke escaped from the back of the TV and now I have no picture just sound. Is it dead?


No troubleshooting needed for this issue. Check the tv's warranty then call the manufacturer to get this tv replaced or fix. If tv's out of warranty you still need to call the manufacturer to ask where is the closest Service center that can fix your tv.

My Vizio LCD TV screen fades to dark. Sound stays on.


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.

Polaroid 4241-TLXB wont stay on


I think I may have just solved this issue. Remove the back covers and turn the tv on until it the screen goes black. There will be a little red led that will light up when the screen goes black. right above that light there is 4 little swiches, the bottom one is labled BURN. Switch that one to the opposite direction. I don't know how but mine has been working for a couple days now with no issues. GOOD LUCK!
