    SONY KDL 43w805c does not accept commands

    Hi, guys. This TV stopped to accept commands and it does not matter if i am using my remote control or the buttons on the TV. It is accepting it sometimes but only once or something and then it is stopping again. Only the volume command is working even i cannot see the graphic scale every time. But the volume is working - i can adjust the volume without problems. I reset the TV few times but it is the same. Now it stuck on the Welcome Screen and i cannot move forrward. Do you think that the Main Board could be a problem?

    If you disconnect the wifi connector does that help. I think it's connected to the IR sensor module.?

          its much firmware issue, as its android 5. there are update for years 2019 to this set- you need to try
          1- hard reset from power & volume - then plug it in wall socket..
          2- to by pass the first installation and to to apply update use air mouse with the tv. or any USB 2 mouse.

                  So, did hard reset few times but did not try with the mouse. Will try it now. The TV is with the last firmware downloaded from sony website.

                    with mouse you can setting the tv as u like... the Notification graphic scale should work again after the hard reset... because its can turned off via setting.

                    take the batteries out from your RC in case the RC keep sending IR signal.. then use the side control panel .. you can try android APK too if you have android mobile with IR sender such galaxy S5. i think sony they have apk too to control the set via net work too.

                      Yeah, but the point is it stuck on the welcome screen. So, i cannot use any APK to control it via the network until the tv is not connected to the network. And my problem is not that this volume graphic is missing... The problem is that it does not accept command neither from the remote control nor from the side control panel.
                      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?

                        f you did hard reset as press power and Volume - then plug set in AC and it show for you erase on screen .. then Air mouse will work.
                        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. if this not help need to open the cover and show me the main boards to see which version its.

                          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 to be sure you did hard reset correct..
                                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

                                      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.

                                        Yeah, i found the same but it looks it does not work. And can see the comments under the post, seems nobody has success with that rollback
                                        I tried and using your advice, Diah
                                        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
                                        It looks i need to looking to buy Main board

                                          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,...
