Check if headphone audio also drops out.
Check if digital audio output, if it has one, drops out.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Previous owner said TV just went blank one day.
They attempted to open the back panel and yanked the power connector off the power supply in the meantime.
Easily fixed that and got the TV to turn on. Backlights come one with everything connected. Good Sign.
The mainboard shows signs of life (red light on digital audio out is on) but that's about it. Good Sign.
There is not blinking LED and the most importantly there is LED response and sound when I press the MENU button on remote control. GREAT Sign.
I just downloaded the Sony KD-75X7800F Service Manual and... -
Finally got my KD-50X690E up and running after replacing the power supply. Upon testing it I noticed the lack of sound from the speakers. At first I just ignored it thinking it was set to external speakers or some other kind of audio setting. However, after actually going into settings and looking around I see nothing of this sort. I looked it up on Google and apparently a lot of people have disappearing audio on a variety of Sony TVs 🙄. I'm going to see if a firmware or software update will resolve it, if available.
Has anyone else had this happen to their tv?

Hi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted...
