Question about Sony KDF-E55A20 55 in. LCD Television

1 Answer

I have vertical bars on screen

I have vertical bars on the left and right side of the tv screen they started out narrow but they are getting wider now. Is there an adjustment that can be done to get rid of them or is it something serious? The set is only a little over a year old.

Hello,

The T CON board of the television is bad, you need to replace this
The T-CON (Timing Control or LCD controller) board (on the LCD panel assembly). It transfer the universal image signal of TTL and LVDS signal to specific TFT (Thin Film Transistor) LCD.
This is the interface board that talks to the Logic board and the LCD panel to produce pictures on the screen. White/gray glowing screen when it fails or not getting the voltage from the logic board (the 5 or 12vdc is supplied by switched transistor on the logic board). Notes: T-CON board is mounted under the metal cover shield.
Common failures:
Scrambled pictures, Lines, multiple pictures, color smears/blotches, rolling pictures after warm up.
Blown surface mounted fuse.
No pictures, very dark screen almost like there is no backlights.

Hope this helps........

We can hear it but the picture is very narrow in the middle if the screen


If you are referring to a horizontal line or bar, you will have to resolder the vertical IC. You may also need to replace the electrolytic capacitors that are almost next to the same IC. Now if you have a black vertical bars on the left and to the right side of the screen, you have a horizontal problem. Bad electrolytic capacitors and bad resistors in the horizontal deflection area of the TV board! Thanks for asking and give me a few hands of support!
