    any way after it reset you hear the start sound.. can you increase it and decrease the sound with RC ?
    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.

    my last advice before you go to buy main boards.. be brave and head up forward your kitchen LOL .. heat your oven and let one flat oven plate at the middle.. and preheat the oven to 275 ( dont use air option. just the top and down heater ) after it reach the temperature place the boards on the plate ( put heavy weight on the chips so all joint point to be sure have contact to the base ) close the door.. wait 10 minutes then just turnoff the oven and open the door leave it on the plate dont move it until cooling down

    i am sure here many good users from UK will help you by where and what to buy and how to use as they used it before over this forum

    Sony HCD-HX80R Amplifier Volume Control Problem
    by crackedprint
    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...

    Vizio D65x-G4 Volume changes on its own
    by karthur
    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....

    Sony MHC 6600 volume clicking
    by Ruptor
    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...

    Sony STR-DN1030 Distorted audio when Volume adjusted
    by jason123
    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,...
