Re: Sony KDL 42W705 backlight no sound, no picture

If they are identical, can I assume the problem i have mencioned is on the LCD panel or that is nor conclusive and the problem can be at the T-Con but on other part (not the fuse).

Forgive me the questions but I will open the TV and I would like to be conclusive at that time to see everything when the tv is open. Furthermore english is not my language and sometimes I don't understand words (i use Google translation...).

Thanks again

Hi, I have the Same problem, I measured the F101 and I have on both sides 12,5 VDC, so the fuse is Ok.
Bu tI don't have picture only sound.
Please how did you solved this problem?

Screw your tcon board back down. Black lead on chassis. Red lead on one side of the fuse and read dc voltage, then red lead on other side of fuse and read dc voltage and the readings should be identical.

Dear Sir,
Same Problem here, Fuse 101 is ok , on both sides 12,5 VDC
only sound no Picture. without service manual its difficult to find the problem.

All feedback is welcome
