Please guide me to troubleshoot my TV Problem
Sony LED TV
KDL-46EX520
No Picture, but the Sound is OK.
TV Channels are working without picture.
Backlight appears when the TV is Plugged-In
Fuse on T-Con is tested and is OK

Regards.

Hi,
If the backlights are staying on, the main suspect is the
main pcb. If you can get a picture using a scart lead to
another set, probably a fault with the processing of the
video signal.
You could try a software update, this can be downloaded
from the Sony site, worth a try,

Regards
