    Samsung UE46F5000AW shorted P.S.

    Hello,

    Found my self a new challenge...
    Samsung LED TV UE46F5000AW whit fuse blown. I know i have a short because if i measure resistance between the + and the - from diode rectifier i get 0 ohms.
    Now how can i proceed... i could not find a good and complete schematic for the BN44-0010B power supply.
    Does any of you have one complete?

    Could it be the rectifier him self or maybe the capacitor just after this one.
    All diodes and resistor measure just fine.
    I guess i have to remove parts to measure cause until i don't find the short... well everything between + and - will read shorted!

    Any one that had the same issue and fix it?

    I posted the pictures from the supply board.

    Thank you!

      Things I would check would be the bridge rectifier, the diodes and the mosfet.

          Maybe lift or clip a leg of that one diode you mention and check it out of circuit.

              I always check shopjimmy.com for the model #. Sometimes they sell a repair kit. Don’t have to buy it but it shows some of the common parts that fail. It might get you a good starting point

                  SAMSUNG PLASMA TV PS51E550D 1W shorted BDXXX on board
                  by LanTHrusteR
                  SAMSUNG TV PS51E550D 1W,
                  Symptoms: the panel is on but no picture, fuzzy color vertical lines at the black background at both sides of the panel. Very similar to this:


                  Disconnecting left side of the panel fixed the right side which went on and displayed picture although with vertical black bars coming from the middle X-BUFFER panel at the bottom of TV and the same 1 fuzzy color vertical line ~ 0.11 inches long and a few 1 pixel black bars. The disconnected left side showed fuzzy colorful bars, may be some glimpses of the the correct image from menu at the right side...

                  Panasonic TC-P50S1 shorted TXNSC1EDUU (TNPA4782AB) SC Board
                  by Yanleb
                  Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.

                  I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :

                  D608, good
                  D618 RF101L4S, good (See warning 1 below)
                  D619 RF101L4S, good (See warning 1 below)
                  D865 RF101L4S, shorted (See warning 1 below)

                  Samsung QN65Q60RA boot loop “shorted lcd” repaired
                  by S14Sr20det
                  Hello all. First time posting but long time lurker here.


                  First off I am not expert but I do know my way around electronics and have a fairly good grasp on troubleshooting them.

                  I acquired this tv for free from a neighbor who had a repair man out and diagnosed it having a shorted lcd panel.

                  Symptoms were that I would start up and reach the Home Screen and work for thirty or so seconds then the lcd would fade to black and enter a boot loop where it would get shorter with each attempted boot.

                  Went through the basic trouble shooting...

                  Samsung B2030HD IR Remote Receiver Dead, shorted micom?
                  by jesterace
                  Hi,
                  I have this TV a small 20 inch that works perfectly except for the IR has stopped. I have confirmed that the remote control is fine and tried an alternative and even tried with IR blaster from phone. Remote 100% ok.

                  Tried installing latest firmware but no change.

                  TV won't respond to remote at all, not even to bring it out of standby. I have to use the touch sensitive front panel to operate, at which point TV is usable albeit with no remote.

                  Tried replacing the IR receiver diode/bulb on front panel and no change so put the old one back. After tracing...
