    Gateway TA7 Main Fan Error

    I turn on the laptop and after bios post I immediately get:
    ERROR
    02FA: Main Fan Error !!
    !! Please turn off system and check your CPU fan !!


    Doesn't even post to HD or anything.

    Tried at first connecting the fan directly (always) on and doesn't work. Replaced the fan with a new one and still nothing.

    What gives?

      Re: Gateway TA7 Main Fan Error

      found this on net worth a try ....not exact same model but same error...


      Fixed the problem of “02FA Main Fan Error” on Gateway M-6866 laptop. Computer would not boot up.

      I had tried several things including removing the RAM, replacing the fan but none of them worked until....I lucked out with the fix described below.

      The Problem:
      - When I hit the start button, fan speeds up for a few seconds then stops
      - Get an error message: “02FA Main Fan Error”, “please turn off computer and check CPU fan”
      - Computer won't boot up.

      The fix:
      - Unplug the computer A/C cord from the computer
      - Remove the battery
      - Press and hold down the start button for 30 seconds (with no battery or A/C cord inserted)
      - Plug the A/C cord back into the computer
      - Start the computer as normal
      -- Note that the computer may give you a message that the computer was not shut down properly, and ask if you want to start in “SAFE MODE”
      - I hit NO, and the computer started up normally.
      - After the computer fully boots up, shut it down normally
      - Disconnect the A/C cord, re-insert the battery and the A/C cord and re-start the computer
      - That is all I had to do to fix it…….works fine now.

            there are some possibilities ;

            bad fan controller ic,
            bad fan,
            wire or connector probem.

            anyway find the schematic and first change the fan with a good known one. if still fails search the fan control part of your schematic. first check the smd components if there is no problem then change the ic. still nothing chnged find whic ic is controlling the fan control ic. Mostly power ic. check the connection between the ics.
            hope it helps.

              Sony RB2G Chassis KDL-55W815B MAIN BOARD 2 Blink Error issue resolved! Happy days :)
              by cheeky2
              For anyone interested just repaired this Sony Main board TV that had a 2 blink error code, the chassis is a RB2G which is common to quite a few different Sony models. The Ceramic 10uF 25V X7R 1206 capacitor C9114 was shorted which took the smd 2A 0603 fuse out F9101. This was powering the Buck converter TPS54332 which caused no 5V output from it.
              See the attached picture of the locations of both components. I also attach the best service manual I found for this board for anyone else in a similar position of trying to repair this main board. It's not specific to the TV model however it gives...

              Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
              by cheeky2
              I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
              Obviously the same LVDS connector for the screen connection...

              Sharp 80” long short flash backlight error - Help
              by Superbee_dad
              Hello Sharp TV experts
              Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.

              > I checked voltages on the power supply board and they all check out .. including 3.28 volts at the error pin.
              > There is power to the cpu and T-CONN and no faults found there. The cpu has a flashing...
