    43pus6401/12 - no picture, blinking ambi lights

    Hello i have 43pus6401/12.

    After turn on red light slowly blinking and ambilight blinking randomly, different colors fadein/out, etc

    Screen is black, no backlight. Caps look normal. I didnt measure it, I forgot my multimeter in another car.

    Any common issue?
    Thanks

          Firmware or cpu fault, these Phillips boards are trash.

                  Replace led strips when you have no backlight and there is ambilight. When you take a good look when the tv starts up you will see a dark Philips logo in the middle of the display.

                      Lenovo ThinkPad E14 Gen 5 - Not Powering On - 3 Blinking Lights - 20 volts 0.224 amps
                      by bialag
                      Hello,

                      I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.

                      Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,...

                      Sony XBR-75X950G seems dead with a black screen but backlight and sound is working and no blinking red lights
                      by Audeze
                      I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

                      Does...

                      T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
                      by Tr0ll
                      Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                      The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                      Original T-con:
                      Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                      First replacement T-con:

                      I thought it might be t-con and ordered new t-con from china(supposedly tested)...

                      Philips 55PFL6008K/12K Ambilight not working
                      by dominik0801
                      Hey,

                      ---
                      I just got the TV mentioned in the title the other day.
                      Yes, I am well aware of it being a QFU chassis which is very hated - although I love QFUs (maybe for being this bad?), my main TV is a QFU too, and I bought this TV for this very reason.
                      It had the typical 2 blink error, which was fixed by a proper Fusion CPU reballing, with extra cooling mods. It works.
                      ---

                      Everything is perfectly fine with it, but the Ambilight just won't do anything.
                      At all.

                      Won't work on Dynamic, won't work on Static. Not a single...

                      Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                      by TR103
                      Hi, I have a Samsung UE50TU with:
                      - sound and backlight, but no picture
                      - when it arrived, it had a picture for a few seconds
                      - it keeps rebooting
                      - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                      - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                      - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                      - without cable between mainboard and lcd panel and with a jumpered...
