    panasonic 42E5X need advice before buying hdmi IC

    hello guys,

    got a panasonic tv lcd 42E5X series, totaly dead after storm lightning
    on inspection, the fault seems to came from motherboard
    hdmi chip tmds361B si totaly fried (big hole in center), have to search on service manual to know which chip it is lol

    don't see any damage at inspection, do you think it is valuable to buy and replace or this motherboard became just a crap ?

    thank you

    Try to remove that chip and see if TV comes back to life.
    Could be more damage than just the chip.
    Check power supply too.
    And tmds361B can be easily found on google.

      Be careful, a new chip would probably have to be programmed with correct edid, if the service menu permits a copy of this data from the firmware then ok... check near each hdmi port, maybe there are little chips , one per each, and one of those broken

        hello

        thank you for help, just remove it for now and rework burnt lines
        but i have an issue with psu too, damn.
        got no stable outpout voltage, and only drain voltage on primary mosfet
        the source is short, refers to manual, the only way to remove short (but not try to plug in) is to remove resistor R7102 R7101 and R7108, without them D7212 pass through only in one way. with resistors soldered, shows 0 ohms resitance both ways.

        don't understand that

        thanx

          Windows 11 buying advice needed
          by Hondaman
          My mother may soon need to upgrade from Win7 (to continue safe browsing, e-mail, and office tasks, without a printer). Right now, she uses an Intel Core2Quad 9550 CPU (not sure of motherboard). Video is either the Radeon 6670 or 6770, completely air-cooled, with fins like a motorcycle engine (I think I pointed a 120mm fan at it). PSU is probably Seasonic, still running after 14 years (I choose quality). I am not sure of the RAM, or the PCI-e wifi chip. Probably 8 GB or 16 GB. Perfect for WIndows 7.

          She does not want to switch to Linux. And she does not want to use a laptop because...

          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..
