Where there is anything in picture that is white in colour, the white area is filled with a scattered pink colour-


could be 1 of two things - tcon board or av board. I'd check th etcon board first though. I just replaced a tcon board that caused the screen to look like a picture negative.

Thanks,

My sony bravia kdl46vl130 goes into standby flashes red 5 times no picture no sound


Information from Sony:
TCON Error 5X
Communications have been lost between the video processor on the FB3 board and the TCON (TFT Control) board which is part of the LCD panel. This can be caused by a defective FB3 board, a defective LVDS cable, or a TCON failure.

Snowy, reddish, weird picture


If the menu and OSD are OK, that probably eliminates the panel and TCON board. That still leaves the A3U board which does all the switching and intial processing of the video signal and the B board which does final video process and panel drive. The is one simple way of narrowing it down: hook up a PC to the 15 pin VGA connector (make sure the PC is set for a 60 hertz refresh rate). If you can see the problem when using the computer input, it is most likely the B board. The B board is the most likely cause of video distortion problems. Please be sure to rate this solution. Thanks!
