    I have just done a few quick tests and found the resistance across the SC board power connection is 12 ohms , the reading across the SS board power connector is around 1 .3 Meg Ohm. Does this seem too high a resistance across the SS board supply ?

      wrong question. does 12 ohms appear to be a short cct on the SC?

      answer is yes. I would use the search function and target posts on any 2010 FHD model and also TNPA5105 or even TNPA5081.

      There will be plenty of info but basically the SC has shorted, that shorts the P board, that then triggers SOS 4. other common code would be 10 blink.

        Panasonic TH-50PX8EA Black screen, only relay clicks
        by Rensiee
        Hello,
        I have been reading a few threads on here regarding Panasonic plasma tv's. I've found one thread which explains the same problem as mine, unfortunately the thread has not been completed.
        I got a free tv (TH-50PX8EA) from a friend which shows no screen. When plugged in only one red light shows up and when pushing the ON button, the red LED turns of and will only turn on again when pressing the ON button again.

        When plugging in the TV i hear two relays click fast and after a few seconds the third relay clicks.
        I have measured the voltage in the VSUS line, which...

        Burco boiler power problem
        by CuriousJohn
        Burco BCPLSAFWM5L 5 Litre Wall Mounted Automatic Water Boiler With Filtration UK 240v

        Does anybody have any experience with these Burco units at all there is no record of them on the forum lol and a proper service manual would be nice. I invite you all to pesuade me not to botch repair it with a 5v relay, read on.

        This unit was rescued from a skip 3 years ago, the only fault it had then was no backight display (plus it wanted a new probe set and top seal) but the screen was never an issue you can still see the screen as is and I just use it to get 5 Litres of very hot...

        Panasonic TC-P55ST50 8 blinks then no blinks
        by Andre Gilbert
        Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing hereπŸ€”?
        Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting πŸ˜‚.

        Repair Success! Middle Atlantic UPS2200R-IP
        by valvashon
        Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.



        Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting...

        Biomass Boiler not driving cleaner motor relay. ENERTRES BIOMASA BI-650
        by edugimeno
        Hi everyone!
        I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
        I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
        This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
        To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
        I respected the polarity, positive to cathode of protecting diode
        So provided all...
