    Re: Haier LE46A2280 all remotes (any button) cause volume to go up.

    I think I might have it figured out. The wire connector going into the IR sensor board has some of that oily stuff in it, and it's conductive. With the harness removed from the TV and nothing connected I should see OL when probing different wires, but instead I'm seeing between 1MΩ and 20MΩ. I'm going to clean it up and see what difference it makes.

        Solved! It was the conductive goo that dripped into the connector. Pulled all the wires out of the connector and cleaned everything real good, now it works perfectly again.

                I just knew it had something to do with that goo.

                    So, there were 3 bad resistors on the key control board. One was a 20k, two were 3k. I was able to find a 20k on another board. Couldn't find any and 3k resistors, but I did have some 1.5k through hole resistors. As you can see from the pictures, I made it work with what I had. My girl will be quite happy to get this back tomorrow. The only bad thing is she wants to keep the 32" Seiki I loaned her. I should have seen that coming.

                        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 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...

                        Marantz SR5007 popping on volume change and mute in Direct Mode
                        by BigOof
                        Hi,

                        I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes....

                        Samsung Soundbar Q900T Cuts Off if Volume above 30
                        by Storyteller12
                        I have this soundbar and when I turn it on it works until I turn the volume above 30.
                        Then the display show “PROT” protection and shuts off.

                        I can turn it right back on and it works until volume hits 30 again.

                        There is a little static on the surround speakers so I unplugged them but still have same problem. I tried unplugging all speakers also and when volume goes above 30 it shuts off.

                        I can turn the volume above 30 if nothing is playing but as soon as I play something it shuts off.

                        It will play fine for hours with volume...

                        Sansui Integrated Amplifier replacement volume control troubles
                        by Coert van Dorsten
                        Hi all you clever electronmic gooroos!

                        I was wondering if you could help me with the below issues Im having on a Sansui Integrated amplifier. I bought this unit as a project to repair as Im playing around with basic electromics.The unit has a faulty volume control pot. The service maual refers to a 150K Logarithmic pot (A) tapered stereo. Im struggling to find this value. Seem to be a jump from 100K to 250K. Im now trying a 250K pot. It works but the problem is that as the volume is turned up from starting at Min the Left channel will come on first just slightly before the Right...
