good night! I have a problem with this TV. the sound of the channels does not work, but the sound effects of android are heard. I think it must be nonsense, but I can't figure it out. I have measured voltage on the speakers, and it gives 6.2 v on each terminal. I have measured in the main connector towards the speakers and there are 6.2v in each output cable. I have measured in the 4 coils with the same result, and in the chip, with 12.2v. I do not know if this will be correct, and where to make measurements. Let's see if someone can help me. thanks in advance

Re: Sony 49XD7005 no sound
well speakers are working, has anyone been messing with the sound settings? see if you can reset sound settings from menu, maybe try plug a 3.5 plug into the headphone jack, plug it in and out a few times in case its acting up and stuck or something.Last edited by nomoresonys; 12-12-2022, 05:01 AM. -

Hi everyone,
I'm troubleshooting a power supply issue with a Sony SLV-E780 VCR. The device clicks repeatedly but doesn't power up completely. I've already replaced five capacitors, but the problem persists.
Here's a video link https://photos.app.goo.gl/3Xki6yvCLn67gLX78 showcasing the sound. Based on your experience, could this be due to a transformer, diode, or another component? Any guidance on what to test or replace next would be greatly appreciated.
Thanks in advance for your help! -
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 have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

Hey Guys,
So a few months ago my Sony XBR 49x900e TV screen stopped displaying the picture but the backlight comes on and I still get sound when I use the remote and navigate to certain apps. I haven't checked anything with the meter yet but started with ordering some replacement boards. I've tried replacing the BMKS board (used from ebay) and also completed the firmware upgrade based on Nicks TV repairs youtube video. I've also replaced the TCON (twice) and PIB.
All of these changes have resulted in the same issue with no picture. I've also tried disconnecting the ribbons...
