    Free Sony Bravia KDL-46EX723 no power relay clicked

    What's wrong with this world?

    Sony TV Bravia KDL-46EX723 no power, relay clicked (Feb 2011). which has been thrown in a dumpster.

    Just right now, It took me 10 mins to fix this TV. It take longer to write this Thread.

    Mine is totally different problem from this Thread.
    Sony Bravia KDL-46EX723 - 4 blink code
    https://www.badcaps.net/forum/showth...t=32245&page=2

    I thought I could use for parts, then I inspected the screen it seems ok. Found R6548 0.1ohm resistor open (common problems, Sony use resistor as a fuse). Rule of thumb, never put back the fuse, check it out, found 2 Mosfets had shorted Q6703, Q6702 are
    p9nk50zfp. I said to myself, what the heck, they are all the same thing. I grabbed two FETs ( FDP18N50) randomly, change it, and the tv has worked since then.

    p9nk50zfp by STMicroelectronics N-CHANNEL 500V - 0.72Ω - 7.2A Zener-Protected SuperMESH™ MOSFET.

    FDP18N50 N-Channel UniFETTM MOSFET 500 V, 18 A, 265 mΩ

    Forgot this: R6548 0.1 ohm resistor replaced with 0.5A fuse.

    I finally got myself a Smart wifi TV which I had been (dream on)ing.

    Oh!!! What A Wonderful World !!!

      Update: This Sony TV keeps going on....


      3 parts has been changed

      Q6703, Q6702 : p9nk50zfp sub randomly with FDP18N50 (near to me)
      R6548: 0.1ohm resistor sub with 0.5ma (maybe 1A is better).


      Skype client, WEB browsing, 3D this few functions I don't know how to use, need to order remote first.
      All the nice TV ,I fixed sell it first, kept only the old one for myself.

          Sony Bravia KDL-40V2500 that will not power on
          by PopsCaps
          I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
          I do not hear any sound and I cannot see any backlight.
          I have tried disconnecting every cable on each board one at a time to see if anything changes.
          The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
          My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...

          Sony bravia kdl-43w755c - boot loop
          by justin35
          Hello,
          i have this sony bravia kdl-43w755c which boot loops. After sony logo, it shows the android animation loading then it restarts…
          from what i read online it looks to be an emmc issue…
          i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
          i took out the board and say an samsung 16gb emmc
          i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
          i could try to put one instead of the 16gb one, but will it work?
          where do i get the software from?
          any help will be much appreciated!...

          Trying to Save - SONY BRAVIA KD-75X780F - No Picture BUT there’s sound
          by KYBOSH
          Previous owner said TV just went blank one day.
          They attempted to open the back panel and yanked the power connector off the power supply in the meantime.
          Easily fixed that and got the TV to turn on. Backlights come one with everything connected. Good Sign.
          The mainboard shows signs of life (red light on digital audio out is on) but that's about it. Good Sign.
          There is not blinking LED and the most importantly there is LED response and sound when I press the MENU button on remote control. GREAT Sign.

          I just downloaded the Sony KD-75X7800F Service Manual and...
