Re: Sony LED TV KDL-46EX520 No Video, but the Sound is OK.
Sir, I don't know what has happened because there was nothing where some thing could be shorted.
I touched one point on the fuse and it gave 12.35 volts
But when I touched the other it stopped working at all.
Is it that the T-Con has destroyed....?Leave a comment:

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
In the start of the problem, the video came for few seconds and then gone.
I replaced the capacitors as shown. But no effect (No video but only sound).
I also tested and replaced the FETs (KF 5N50).
There is dim blue light on the screen. Sound OK Channels are Tuned, But No Video
Regards.... -
