    Philips 32PFL5605H/12 issue with displayed colors

    Need help with this unit...looks like the colors are not displayed correctly....not an expert, but looks like something wrong with the GREEN...have attached the photo of the 'home menu' and the recorded video of the Demo video that's on the TV for viewing/testing.

    Where should I look for faults? Everything else looks/works ok.

    BTW...have upgraded to the latest FW/SW version, but nothing changed.

    I remember Philips of that period have black menu background, i'm not surprised if the tcon is at fault with the common as15 chip damaged, but if you find it, i would try an experimental method, i would try dry every solder as possible, then reapply new one.. rather than changing the chip.. give it a try.. it's simple, if you know smd jobs... PS: i have not watched the video..

      First check the screencode. Press 062598 menuXXX on your remote, after the code is accepted the TV should go in stand by, if not try again. XXX is the screencode that you can find on the rear cover.

        Thanks for the reply....a stupid question...where am I supposed to look for this as15 chip on the tcon? Checked the schematics that I have and cannot find it mentioned anywhere...

            As15 is on the tcon, no schematics of tcon if it is separate, you have to phisically inspect it, it is a qfp 48pin ic marked as15-f or -h

              this mean it accept the code... if the color remain you need to log in service menu sam and do adjustment at white balance

                  In this TV the tcon is part of the main SSB (Small Signal Board); 'D' on below photo (not the actual unit (photo taken from the Service Manual), but have the same set-up)....there is no separate tcon board...

                      OK, watch the right top side of the main board, there is a QFP chip of about 1cm wide, post a decent picture of that area or tell me its marked code..

                        Loged into SAM and changed the White point settings, but the colors were still off....
                        Must be something else that is causing the issue.

                          Have taken the actual photo of the SSB....hope it is clear enough.

                            Adding some stills from the Demo video, where the issue is clearly seen...

                                Philips 55PUS6804/12 turn on & off (probably backlight issue)
                                by ovrax
                                Hello everyone,

                                First of all, please excuse me as I'm quite new to this field.

                                I have a Philips 55PUS6804/12 TV. It turns on and off instantly (backlight flash). I personally think it's a backlight issue (faulty LEDs). Could you help me confirm my diagnosis?

                                I've checked and the T-CON seems to be fine. I disconnected one ribbon cable at a time at the bottom, but the problem persists.
                                The Ambilight works perfectly and stays on.

                                No sounds.

                                Thanks in advance.

                                No picture issue in Philips Chassis FTL2.1
                                by charlesdutcher
                                Hello,
                                My Plasma Philips 37inch chassis FTL2.1 does not show picture. It automatically goes into protection mode after 30 seconds (red led blinks at 3Hz)


                                Is there someone having any symptom like this? How to fix it?

                                Thanks in advance!​

                                philips 55pft5500/12 Backlight issue. What am I doing wrong?
                                by DoOm86
                                TV philips 55'' no backlight (image ok).
                                I tested the backlight with my led tester from the unplugged connector cable and it lights up. I had voltages at the motherboard connector, but anyway I order a new psu. Same problem, same voltages. Disassembled the TV and checked every strip with my led tester, they all light up, same voltage for every pair of strip (they go two by two).
                                What am I missing?

                                And something else I don't understand. I checked and I have 3v Leds, 10 per strips. Why every pair of strip (so 20 Led) take about 32v when powered up with my led tester πŸ€”

                                by Nicktronic
                                Hey everybody, got a strange one here.

                                The TV will display the Home Screen, Menus, Netflix Home Screen, YouTube home screen with preview tiles, etc, without issue. As soon as I try to play video (streaming or from any of the HDMI inputs), all I get is audio and and blank screen. It's like the video is not being processed. So I ordered a replacement main board. I can now play video from streaming sources but the video from HDMI sources is all green (kinda like photo negatives but all green) and the audio does not work. Is it possible the main board I ordered is also failing?? I can't...
