    Sony kdl 37xbr6 Blinking standby light 3 times

    So I have this sony that had no picture or sound but had backl ight.

    I found the fuse f006 on av board open (pretty sure) and mistakenly (stupidly) attempted to jumper it.
    I now have a flashing standby light (3 times) and have lost back light also....

    Lost power to f006 on av board after jumper attempt. Power supply board outputs seem dead now also.. Main (big) fuse is good on p/s. Auto switching (fuse?) above main p/s fuse is doing an extra click now also...



    Any thoughts on how not to screw this up further? (besides the obvious one of stopping)

    thanks all

    Doesnt sound good!
    We can sometimes help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back (in the same orientation) and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

    Please do not post inline and offsite as they slow down the loading of pages.

    Examples of what is needed

      I set this one aside for awhile but am now revisiting it with updated Info.



      THE STANDBY LIGHT IS NOT BLINKING LIKE TITLE SAYS... I don't know how to change the title...

      I swapped the main pcb out with one I was told was good taken from a unit with cracked lcd so that should have taken care of the "post 1" screw up...

      Maybye I should have started a new post... But this is where i am at now.....

      I have a sony kdl-37xbr6 that Has sound and backlight with no picture. Other than no picture, turns on and off fine.

      I checked f1 on the t-con and it has continuity but no power to it on either side.

      I checked through a bunch of forums but could not find one that dealt with the fuse not getting power.

      Not sure where to proceed from here. Any help would be great..

      I have attached pics.. Please let me know if anything else is needed

      thanks

        Update...

        Found F1422 (5A 24V) on main pcb open.

        I found reference to this fuse in this other bravia post

        https://www.badcaps.net/forum/showth...2+%285A+24V%29

        Is it a bad idea to jumper across like the guy in the above post did for testing? ? As shown in my 1st post of this thread, it did not work well for me. although its tempting to try since i don't have any of the fuses in question and i want to see results......

        Anyone have any idea what digikeys part # is for this little guy or where to get them?

        If I replace it is it just going to blow again because of possible bad t-con?

        thanks for any advice

          QN750Q8FNBFXZA Service Error Codes Needed - Error code 1-3-1-2 ? Dead set, only blinking standby light in repeating sequence
          by mecha1166
          I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. Thanks!

          Sony Bravia 55HX820 - 4 times blinking red standby led
          by androripara
          Hello everyone,
          i am trying to repair a Sony KDL-55HX820 led TV which is throwing error code 4 (standby led flashing four times).

          I followed the troubleshooting flowchart at page 69, and between pin1 and pin7 of CN6002 i am reading 1.91V so i guess i can rule out the B Board as the culprit.
          Before ordering new G* Boards (by the way, should i change both? it is not specified in the manual) i wanted to try and do more advanced troubleshooting since i've read in other threads people resolving their problems on the 46/55 HX 820/823/825 models by replacing the Samsung led...

          LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
          by ChristianBr01
          Hello everyone,
          I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
          The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
          What I already found is that the 12.8V are not an the connector to the main board connector to the power...

          Sony 55X900E no standby light, no power. Replaced mainboard already
          by noinimod
          No standby red light, nothing
          This Sony has a separate AC->DC power adapter supplying 19.5V to the TV power board (JK3)



          Disconnected JK3 power board from main board, checked voltages on all the pin outs

          At a few pins I can see the power supply providing 19.5V to the main board



          Based on the service manual triage.. it seems to be pointing towards the power board (JK3) being the most possible culprit


          LED light turns on when I disconnect LED driver board ribbon from mainboard (so i thought it is the mainboard,...
