Having problems with your Flat Panel Televisions ?

I have Vizio XVT3D474SV I bought a year ago, in the last week while watching TV, the screen start to flash, display becaome white with 3 black lines and after a while it becomes black (the all time the sound stay as normal). while looking inside I see the backlight flashing till the screen becomes dark (than I do not see any light inside). After turning off and ON the TV several times I get back normal pictures but the same phenomenon comes back in few minutes. I checked all 8 micro fuses I have



Answers :

When the picture is dark, show a torch light on the screen from a safe distance. If you can see the picture, the backlight is the problem. Anyhow, it is better to show it to a qualified service technician.

LCD television starts normal, but after 2-3 secs, the screen turns black and remains black, no picture, but sound is still there. All cables have been checked - all possible input channels have also been tested to see if they produced any images onto the screen. When i look in a dark room to the black screen (with a flashlight), you can see (but very hard to see) some grey images (tv pictures) moving over the screen.

Black screen I have a Samsung un46d8000 flat screen TV which is about 8 months old. It has so far worked without problems but yesterday when switching on there is just a black screen. Sound from all inputs is fine and it looks like that there are 4 small lights in the back that you can see glowing through the screen. Its still under warranty if I can find the receipt!! If I dont find the receipt any ideas? I did have a peek in the back and there looks to be one big board that drives the Screen.

The right side of our screen keeps going dark, almost black. Once I tapped the side of the tv and it popped back to normal. Sometimes it goes back to normal by itself. It is black most of the time though. Is this fixable?


Yes usually fixable unless its the panel goning bad. What if you squeze the panel where the black bar is does that effect it. If so the cabinet is probably bowed. Hope this helps. ... Sanyo Standard (CRT) Televisions
