    Fujitsu PSD4222W-S Blinking red light

    1. My first problem is that I took the back cover off and can not find a way to mount the thermo board back into the set.
    2. Initial problem was that the set turn on and it comes off after 30 seconds of operation. The red light blinks on and off constantly. Supposed to be one of 4 boards is bad or all are bad.
    3. Second. Now that I have the set mounted on a stand I built it does now turn on for any time. The red light just keeps on blinking on. I heard a relay clicking right after the voltage is turned on on the set. Center switch on.
    4. I believed I disturbed the temperature sensor board and it does not work like it supposed to work. However, I tested the board and it seems to work fine.
    Anybody has some advise to override the relay that turned the power off after the sensor determines there is an over-temperature?
    5. Send me a picture of the sensor board mounted into the TV.

    Nobody answer the last thread that I started. I still at a loss. My main concern is where I can get a schematic of the AC/DC power supply. The one that has two relays side by side that turn the power off if it overheat or is not adjuted correctly. If you answer this thread, please tell me how the little sensor board that "plugs" right next to the two relays must be mounted. Also what sort of shortcut can I to turn the the two "safety" relays on to cut off the power. I REALLY NEEED A SCHEMATIC OF THE AC/DC POWER SUPPLY BOARD.

      Hi,
      I have the above tv that just shows a red light blinking twice 5 times, i have taken the back off and all the capacitors seem ok,
      When i disconnect the mainboard from the PSU all the led's light up blinking fast but as soon as i reconnect the mainboard back to the power supply i get the red light blinking again twice 5 times,
      I have attached pictures of the Mainboard, PSU and a small video (zipped) showing what happens when i disconnect the lead from the psu
      Any help would be appreciated...

      AcuRite 5 in 1 temperature sensor replacement repair
      by CapLeaker
      Got a new victim:

      AcuRite 5 in 1 Iris outdoor weather station not updating the temperature / humidity anymore. The original sensor is a SHT21. Also there are identical other sensor manufacturers. I chose the HTU21D to replace the original SHT21. Both have identical specs. I've had two failure modes with these sensors.
      A: outside temp stuck at -40? It's cold here at times in Canada, but not that cold!
      B: stuck at some temperature and maybe updating once in 12 hrs or so.

      Easy solution is to go to AcuRite website and purchase the sensor. Right?...

      Lift Master Garage Door wall switch display / motion sensor controller display disappeared no back light
      by sam_sam_sam
      This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

      I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

      I am comparing them to a brand new one that I installed

      The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

      I going to let it run for several days before I remount back on the wall next to the...
