    Philips 47PFL9603H fault or not?

    Hi all
    I have this Philips 47PFL9603H everything works except for speaker outputs.
    Even headphone output is OK.
    In audio usermenu there is an option "TV speakers on/off" but it's all grayed out. It cannot be selected.
    Tried factory reset in user menu, went into SAM mode checking option numbers, they all are exact like option codes on rear cover.
    Wonder if this could be a corrupt mainboard or any else weird feature??

          Not sure on this model but some similar ones I've had have a 24V rail on the power supply labeled AUD (Audio). I had one power supply that wasn't putting out power on these pins and a second TV that simply had a loose connector between the main and power supply. That TV was showing the same symptom you are describing.

              Thanks for advice. "Unfortunately" the PSU supplies the audio (24V).
              Will check around for loose connectors ...!
              Went into firmware update, but the set was already updated according to update application.
              Also replaced the class-D amp chip with no difference (just in case)

                  Philips TV 43pus7505 setting display option code, help please.
                  by eurgenca
                  Hello.
                  I am dealing with a Philips TV, 43pus7505 and is stuck on boot loop.
                  So I ordered a used CPU board, and now I have wired picture.
                  I think the problem lies in display option code. According to SM, the command for setting
                  display code is 062598 + MENU + 032 (032 is written on a label on back of a TV).
                  But as soon I press the menu button TV jumps in menu. Can someone please tell me what I am doing wrong,
                  or can I manually edit option code in SAM.​

                  Philips 55pus6754/12 FZ3A Set Option value dilemma
                  by alltvrepairs
                  Hi,

                  I need to change the main board for this set. I have a new identical board but for a smaller model 43PUS6704/12 FZ3A

                  The picture is not good and remote seems not to work either.

                  The Set Option on the rear of the TV says 042 as shown in pic.
                  The Service manual lists this model but with another screen with a mentioned Option Code of 109. I assume that I need to use the one on the back of the TV.

                  The problem I don't know how to tackle yet is the remote issue as not responding. Remote works on another Philips TV.

                  Philips 50 Inch 6654 4k display fault
                  by Biruslapio
                  Hi, this TV is from the PUG series, had no image, upon using tape to cover the pins on the right side(from the back), it displays only vertical bands that fade away slowly, classic problem with the horizontal part.

                  There is no short I could find on the panel, when disconnecting any major voltage such as VGH, the T-Con stops pulling down all voltages and I can measure what they should be.
                  I tried to use an external power supply in place of VGH, as soon as I turned on the tv displayed proper image and then instantly started to fade, T-Con shut down all voltages, it is sensing...

                  Panasonic SA-MAX770PU SMPSU board fault....
                  by Rictech
                  Hello everyone. 😀

                  As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
                  Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

                  Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
                  This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
                  There are no devices that have exploded or otherwise show signs...
