    Same cause as LG panel aging prematurely, but there's no firmware update for these...

    Notice the poor discharge on the gradients.
    Yep, seen that before.

    Well after fiddling with LG,SAMSUNG and PANASONIC I'm yet to see a PANA with a bad plasma Picture unless it was a fair dinkum faulty board. yet to have one with sparkles and after doing that 2006 SD with a dicky LVDS cable even that looks perfect compared to all the aged LG/SAMSUNG.

      Indeed, never had a Panasonic maldischarge because they got the aging drive waveforms right first time... and even new Samsungs have maldischarge issues... my university has a 2010 Samsung 63" monitor with pink discharge due to poorly set Vs.

          Depends...
          I sold mine to someone who wasn't bothered about the problem. For ordinary TV it didn't seem to be a concern, except when initially cold - it cleared up after around 15 to 20 minutes.

              Mine worked on HDMI, though. Can't say I'd buy a TV without HDMI these days...

                Marantz SR4003 AVR HDMI board issue, seeking for help
                by aliougm
                I have problem with my AVR(Marantz SR4003) HDMI board issue. I connect to my TV but screen color distorted,see attached picture.

                Connection as below:
                Set-top box HDMI output >AVR 3 HDMI input/one HDMI output>HDTV HDMI port
                If I bypassed AVR then HDTV screen color be good.

                I take out HDMI board from AVR and check services manual the schematic shown the HDMI signals path:
                3 HDMI input port > SIL9185 chip(HDMI switch) > SIL9033 chip(HDMI receiver) > SIL9030 chip(HDMI transmitter) > HDMI output port

                I replaced all...

                Certain DisplayPort-HDMI cables can disable HDMI CEC communication
                by japlytic
                With a setup including a TV and AV receiver where HDMI Consumer Electronics Control (CEC) and Audio Return Channel (ARC) functions were working, these two functions stopped working after changing some connections (not the one between the AV receiver and TV), so I believed it was a corrupt setting in the AV receiver or TV, but when I disconnected a passive DisplayPort-HDMI cable (which a Multimode DisplayPort connector supports HDMI with a low cost passive cable or adaptor) connected to a home theatre PC, HDMI CEC and ARC functionality was restored.
                An examination of the HDMI CEC wiring...

                Toshiba 50UL2063DB randomly rebooting with HDMI-CEC and/or HDMI-ARC enabled
                by spleenharvester
                I have this TV hooked up to only an AppleTV 4K and a Creative soundbar. Originally HDMI-CEC and HDMI-ARC wouldn't work at all, I replaced all the HDMI cables with decent UGREEN cables meeting the latest standards, now it all works perfectly but once or twice a day the TV itself reboots while watching a program, the AppleTV keeps running. I haven't fully pinned down whether it is ARC or CEC causing it yet. All are running latest firmware.

                I assume it is just HDMI-CEC being buggy as usual on a shitty Vestel machine, but can anyone think of anything I can try before disabling it?

                LG LCD TV HDMI PORT FAULTY
                by RossMoodley1967
                LG LCD TV picture comes on intermittenly using hdmi port.The sound is on permantly.The hdmi ports looks fine and soldered in securely.The 3.4v coming to the main board is not present(not sure if will affect the hdmi port or where that voltage goes.)The hdmi cable is fine because it works on another tv.The ceramic caps connected to the hdmi controller ic is reading 39 ohms.Could the hdmi controller ic be faulty(feels very warm to touch).The RCA jacks work normally .Thank you in advance for your assistance..
