    lg-32lc41 Keeps changing channels on its own!

    Hi People ,

    A friend of mine has a lg-32lc41 which keeps changing channels on its own. He lives further away so i don't have this tv with me and can't test it by myself.
    Tried removing the remote from the tv and removing the cable/buttons on the tv but it does not help.

    Is this a main board problem? Is it fixable? I know its not much information …. :/


    thanks!

      Bad RF/Input function board. Needs to be replaced. I had a few Samsung panels with this same issue and replacing the part was the only fix.

          Thx for the reply! So thats the board with the buttons? Or the small board for the remote control?

              Before replacing the Keyboard PCB (the one with the buttons on it) try cleaning it with some contact cleaner or isopropanol alcohol.

                  Like tom said, I didn't look up the panel, so if its got buttons try cleaning them.

                  The Samsung ones I replaced were all touch sensitive no physical push buttons no amount of cleaning would save em!

                  Also check for pinched wires or wires that might be rubbing on something and exposed. I had one Samsung that would do nothing no power ect. I took the back off and one of the wires were pinched to the point of grounding to the frame of the TV. How that happened when the panel was never taken apart is beyond me but it probably came from the factory like that.

                  One other thing you might try is having him unplug the button cluster from the MB if the RF board is separate and see if you have remote only functionality.

                      Hi Tom/Shinju ,

                      I asked the guy to give me the TV so i can have a look at it! Thx for the hints , will try them all and let you guys know the outcome!

                      Thx!

                          check the supply voltage to main chip, the voltage regulator IC might have problem

                              the supply voltage to the main chip? what of the MST line on the board? there's an SMD VOLTAGE Regulator there I think the output voltage might go higher than the normal output v. for example
                              output v 3.7v
                              instead of
                              3.3v

                                  by r2digital
                                  Hello, i had this amp sitting in the closet knowing that none of the channels were working. After taking it all apart i found 4 bulging main filter caps so i went ahead and replaced those with low ESR kmet caps. However after doing this it only restored sound to Surround L, Surround R, and Center channel. The main speaker fuse on the transformer F905/F906 keeps blowing so i decided to remove all of the transistor's on those 4 channels and measure them. All transistors appear to be in good working order(turned receiver on with none of them installed and fuse still blows). Checked dual emitter resistors...

                                  by rustinjust
                                  My tv will work for a while and change channels with the remote as it should but then it will stick on one channel only and work ok but it won't change channels. I have tried unplugging it for hours and whilst unplugged pressing the power button on the tv to reset it.

                                  The volume button on the remote still works but it just won't change channels once it decides to stick on one channel

                                  It has built in basic freeview tv here in the uk, I've tried doing an automatic search to reset the tv but nothing works.

                                  LG 55NANO77SRA TV – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
                                  by ygorsan
                                  Hi everyone,




                                  I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







                                  🧩 Problem Summary:
                                  • The TV keeps scrolling through the menu or selecting items by itself.
                                  • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
                                  • The remote control is not in use (batteries removed), and the TV still shows the same behavior.

                                  Hello all, Aiwa TX-110 Tuner got out of storage and the buttons was held in by some gloop, What glue would you use to restick these buttons (they are no snapped off)

                                  Thank you

                                  Hello,
                                  First on my laptop i had a motherboard with a pentium 6100 processor. Installing w11 i was blocked on the 23h2 version...impossibility to upgrade toward 24h2 because the SSE4.2 functionnality of the cpu was missing. About displaying and screen looking all was perfect.
                                  I changed of motherboard with an intel I3 processor...and now i don't find the previous aspects of the displaying.
                                  Now i have a veiled screen and pixels are missing though the graphics parameters have not changed.
                                  Desinstalling and reloading the drivers in the same time on the graphic card (intel hd...
