    Philips 47PFL5028K/12 - Remote Control repair help

    Hello,
    my remote control for my beloved TV (Philips 47PFL5028K/12) is no more working.
    Codes of the remote should be :
    PHILIPS 996590004895, YKF314-005

    It's blinking endlessy when I insert AAA batteries.
    Checked cap seems ok, the transistor (i think is that) seems good
    IC not checked.
    I thought also to a stuck key.

    I switched cap and seemed to be ok but it restarted blinking endlessy again..

    May the IC fail if battery polarity is inverted? because my son told me he did that ...

    The schematics should be quite simple, anyone has it or some hint?

    Best regards

      Has one of your remote buttons stuck down? Has any liquid been spilt on it?
      Willing to help but I'm no expert.

          No liquid for what I know ....
          Yesterday I retried to put batteries inside and began working fine but after a while restarted blinking endlessly....and after other time was dead unresponsive.
          Maybe was working until cap was not fully charged for some IC malfunctioning?

              would try to reheat solder joints.

                  Pioneer VSX-522-K remote control not working???
                  by tmhobadcap
                  I have this receiver for at least 10 years. Usually, we just use the remote for turning on/off and adjusting the volume. Recently, the remote control started not able to turn the receiver on. Later, the volume also could not be adjusted by the remote control.

                  At first, I thought that it was the usual problem which can be fixed by cleaning the contacts on the switches and the pcb. I opened the remote and clean it with alcohol. The remote did work again after that. But after one day, it did not work again. I opened it again and clean with alcohol and contact cleaner. Again it worked...

                  Old Privileg 5.1 speakers remote control question
                  by piipo
                  Hi, I have an old Privileg brand 5.1 speakers. I have lost the remote control. I have an universal Harmony remote but there is no Privileg brand in it's software to add. Does anybody have an idea what alternative brand for a remote can I try instead? I'm attaching an image of what the speakers looks like. The image shows 2 main speakers, they are 5 + 1 in total. Thank you very much

                  Schematic for Denon Remote Control RC1156
                  by hemant_2222
                  Hello Everyone,

                  Hope everyone is enjoying their repairs at hand!.

                  I am looking forward to get the schematic of Denon remote control RC1156. Actually long time no use of the remote leaked the battery thereby corroding few parts as well as the tracks.

                  I was able to join few of them but the remote is still not working, so i am looking forward for your help, in case anyone understand the schematic or the remote circuit diagram and could me assist me in repairing it.

                  Please refer to the attached picture, i think the voltage divider is missing...

                  hitachi 75hl16t64u - not responding to remote control
                  by dfear
                  I have a hitachi 75hl16t64u tv in for repair and it is driving me crazy.
                  It came in for a power issue which I have finally resolved by replacing the power supply.

                  The current issue is that the TV does not respond to the remote control. I have replaced the IR sensor board with a used one but the fault persists.

                  Anyone have a clue how to fix TV?

                  FYI: I have checked the remote work s by pointing it at my camera on my phone....

                  Philips 50PUS6262/12 (chassis TMP17.7E LA) no picture
                  by HP32Sii
                  This is my first post on this forum, and my first attempted repair of a modern flat-screen LCD-TV (though I have repaired a few LCD-monitors, all with Elco-problems (high ESR). I have repaired my fair share of TV-sets and VCRs in the past ('90s) and was fairly familiar with the different Philips chassis (KT-3M, K12, K2, K3, K7 are some that come to mind). So I have a fair bit of experience on old sets. Obviously, modern TV sets are quite a different cup of tea.... no HOT or flyback-transformer inside, for starters....



                  The set came into my possession by accident,...
