Re: SONY KDL 43w805c does not accept commands
you can also try to cause error to let the firmware jump from this test... for example plug it out from wall then plug out the LVDS cable. let it register error.. plug it out and put back the LVDS in placeComment

Re: SONY KDL 43w805c does not accept commands

if you press OK on RC to pass language then press OK again to pass the land the start music should stopped !!! tryComment

Re: SONY KDL 43w805c does not accept commands
Yeah mate i tried that first - to unplug it and thw plug it in the wall without LVDS cable - nothing happened. Then i tried to reset it without this cable. No i am trying to put in standby mode but without success till now. It is just turning on every timw by itself. And yes, i can control the volume when i can hear the sound but that sound it is not comming up every time.Comment

Re: SONY KDL 43w805c does not accept commands
I think you need to do a firmware update/pair, use the usb drive method, hopefully this kdl is one that will update by itself without needing you to do any remote clicks, some do some don't.Last edited by nomoresonys; 02-05-2021, 02:37 PM.Comment

I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.
I have tried a Cold Reset as per the service manual.
I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.
I have looked all the way through the service manual and tried many online... -
On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.
It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related.... -

Has anybody had the problem of the digital clicking from the volume control coming through the speakers. I guess the mute should activate as everything seems to have a mute from the analogue switch LC7822 to prevent output of stuff on the speakers but the mute circuits are really complex. The pcb is very badly manufactured as if it is over etched and not cleaned properly before being screen printed because I have fixed one fault but a wide track lifted off real easy with very little heat requiring extra repair. I dread touching the board so would like to go straight to the problem if someone has...05-21-2023, 05:32 AM -
New to Audio equipment. Received this 7.2 Surround Sound system - had a blown channel and fixed that (0.22 ohm resistor, 2 transistors, and 1 100 ohm replaced)
All channels now work. However, when I raise the volume with knob or remote, it doesn't work smoothly - you can heard distortion, and some speakers don't seem to work at max or somewhere in between..
First thought was the actual audio switch - but then Remote volume control shouldn't have this problem, but it does.
Second thought was the ribbon cable from front display to control board (V-Flex,...
