    Sony KDL55EX500 Main Board Problem

    Hi to all this is my first Post and hoping someone can help

    First off I Run a small Shop, mainly repairing phones and the like but lots of other things as well

    But today someone has bought in the above Board. So got busy looking for the Schematics, Na! could not find them, Sony are no help.

    Anyway, this board has had a fire on it by a Poly Cap (C 6307), taking out C6308 & C6305 and also the Toroidal Inductor at L6301. It does seem to be limited to that though.
    So my Question is, What is the value of the Caps
    The Marking on the Green Caps are: 105J2W R P012 ( The 3 of them are the same )
    and the Toroidal Inductor is so heat affected that there are no indicators on it to give me any clue. Cap C6307 sits basicly hard up against it and it has copped the full force of the fire and heat and as you can imagine all have been so heat affected they can no longer be read with the meter. So if anyone can help me I will be very grateful
    Cheers

      Welcome to Badcaps, What would be helpfull is if you could post good clear pictures of the board, and also the area with the problem, and if there are any other numbers on the board, someone might have a board like it and be able to help.
      Also you should have posted in the "Troubleshooting TVs and Video Sources" forum, you might get a quicker response
      Is this the board?
      The cap.value would be 1uF +/-5% 450 volt I believe those are Metallized Polypropylene Film caps

          tanks for the help with the capacitors, do you also know the values that i need to know to order a new coil. it would be nice if you let me know where to find this information as well. thanks in advance

                  Sony xbr-65x900c main board issues?
                  by jb_Bak
                  Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                  Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
                  Power Board Connector that goes to Main board
                  CN6401
                  Pin 01 NC
                  Pin 02 NC
                  Pin 03 "BL_ON": 0V
                  Pin 04 "N/C"
                  Pin 05 "STBY 3.3V": 3.5V
                  Pin 06 "GND": N/C
                  Pin 07 "AC_OFF"...

                  Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
                  by Dani_2024
                  Hi and thanks in advance for any input you might provide!
                  I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                  Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                  Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                  (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change

                  Issue: No Power, Then Rebooting After Main Board Change

                  Short answer: replace main board and power board
                  Technical answer: replace main board and Q306 & Q307 on power board.

                  Long answer:

                  TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

                  by m1ch43lzm
                  Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                  Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                  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...
