    inset it in USB Port Ver 2. and do the procedure as you doing hard reset. you need to release the power & Volume - only when you see the usb led indicator start blinking

    1-while the set on plug it out from wall socket
    2- plug out any cable / antena etc from the set ( keep it solo )
    3- press on the tv side panel volume - & power and keep press then plug it in wall ac again.. the front LED will change to green... after it change to green release the keys you pressed before.
    4- leave the set it will reset and it will show you first install but it will reset again and reboot..--- this mean after the set rebooted 2 time and the first install remain on screen the set finished reset.

    you must use air mouse. because its plug & play with android
    Yeah, mate! I did that few times. I can see the green led light and you can see that my TV is coming in the first Welcome screen after hard reset.

    put the last update firmware on USB stick not larger than 4GB formatted FAT 32... inset it in USB Port Ver 2. and do the procedure as you doing hard reset. you need to release the power & Volume - only when you see the usb led indicator start blinking. do it many time until you succeed.
    Did that about 10 times but nothing - it is just looping in the boot logo and turn off again and on and off ..... May be it is not possible to reflash it with the same firmware version. Found some procedure for downgrade on Internet but cannot find older firmware for my TV.
    if this not help need to open the cover and show me the main boards to see which version its.

    Just tried with the mouse now and nothing - i can see the mouse coursor and move it for 2-3 sec and then it is freezing for few sec and so on.... Is there how to reflash the TV with USB stick even it is with the latest firmware already?

    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,...
