    Re: sony STR-AV310

    What caught my eye was 63Strat's post: "My STR-AV970X used to cycle on/off and then slowly turn its volume knob all the way up to ten slowly as if a ghost was doing it". (If your last setting was on a radio station, my 1070 would do it in the middle of the night and scare the crap out of me!)

    When I recieved this used 970, the first thing I did was open it and tighten all the grounds, already knowing that issue from my previous 1070. I'll give that another shot, try the polish up or hard wire method.

    I'd love to be able to find if there actually WAS a Sony bulletin on this!

        Re: sony STR-AV1070

        My STR-AV1070 has problems of not turning off.
        The vertical circuit board behind the volume knob becomes disconnected from the horizontial main board on the bottom of the amp. Behind the volume knob, if I squeeze the amp bottom and top together in the middle of the right side of the amp, it connects the 2 boards together and you are able to turn the amplifier off.
        I can only guess what other controls this solution can fix because the Vertical board behind the volume knob being disconnected from the Horizontial main board should not happen.
        Take the top cover off and you can see where the 2 boards connect. the vertical board is connected to the volume control and the on/off switch.
        Good luck.

            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,...
