    The photos remain in the archive. The upper capacitor has a power supply of 3.3v (blocking), you can set it to 0.01 -0.1 mF, but you need to know the lower one, since it is gray, it is more likely to be pF....

    But your upper capacitor was not blown away by the station, but knocked down, since the remains were left on the seats, before you it (TV) was already repaired or tried to be repaired, it looks like when they installed a clothespin from the programmer (without desoldering the chip itself) to read, write dump , and the capacitors were damaged...

      You are an absolute genious Sir for figuring this out.
      After reading this post i realize that i am indeed im the guilty culprit.
      i was using the clothespin connector to read the chip early on. The connector is a cheap one that came with the programmer and it was losing the ability to grip and stay on the chip. The plastic on the end was wearing out so quickly. I struggled may times to get it to attach to the chip in a secure way and be able to read it. In the end i tossed the connector and started removing the chip with hot air. I must have damaged the board messing with the connector. Thise caps are so small i could not have known that i ran the risk of damaging them.

      i only have 1206 sized caps on hand at the momentum. I may have to order a book of smalller SMDs for this job. Thank you very much for the assist and guidance with this. Very happy to have learned so much. I will be twice as careful next time!

        Im circling back around to this one about to order an assortment book of SMDs to fix my fumbling.
        I grab my calipers to verify and frightened to see that I need to order 0402s

        I have never dealt with SMDs that small before.... But Im going to give it a shot!
        I dont think the pads will accommodate a 0603.

          Trying to Save - Samsung 65" The Frame (QN65LS03B) with no signs of life (One Connect Box)
          by KYBOSH
          I picked this one up today.
          Previous owner says no signs of life.
          TV looks immaculate and its a 2022 model year so I thought maybe the one connect cable was damaged.
          Got it home and put it on the Kill-A-Watt power meter and it was completely dead.

          The TV model is QN65LS03BAFXZA - version: CB06
          The One Connect Box BN44-01066D / BN96-54788Q / BN39-02470A.

          I immediately remembered EazyBone's Samsung The Frame TV no power....One Connect thread and am preparing myself to tear the One Connect open and hunt for dead parts.

          Will keep you all...

          Samsung 225MW EEPROM bootloop
          by Jacksoft
          Hi all,
          I got an old Samsung 225MW TV with BN41-00825 motherboard.
          Since the TV has a buzzer when it starts it makes a beep. The main problem is that the TV goes in a sort of bootloop and beeps every 2-3 seconds.
          So I attached the VGA UART cable and read the debug data using a RT809H programmer:


          According to the Service Manual all the voltages looks good, so I made a backup of the internal flash and all the EEPROMs (1 Settings + 3 EDID) and cleaned the EEPROM.
          Now the TV boots but it's stuck on VGA. If I try to change the source it goes to TV, restarts...
