    Found Philips capacitor in an old CRT (Philips 37KV1232)

    I fixed another CRT TV, a Philips 37KV1232, chassis GR1AX

    I found 5 bad caps and replaced them. One of them was Philips 220uF 16V with real capacitance 45uF and ESR ~8ohm, not bulging though.

    The colors were bad and I found that 1 of the 3 transistors on the board on the neck of tube, a BF422, was bad and I replaced it. The colors are good now. Not great, but acceptable for a 20 years old TV.

    Philip's capacitor (and other passives) business was spun off to BC Components, then Vishay BC Components.

      Title:
      Capacitor detached from PCB – RTX 2070 Super Founders Edition

      Description:
      During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
      I did not notice it detaching, so I am unsure of its original location on the PCB.

      Procedure performed:
      - Removed backplate
      - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
      - Reapplied thermal compound
      - Reassembled card

      Observed behavior after reassembly:
      - GPU powers on and operates normally under...

      Philips 32PFL5605H/12 issue with displayed colors
      by croupier36
      Need help with this unit...looks like the colors are not displayed correctly....not an expert, but looks like something wrong with the GREEN...have attached the photo of the 'home menu' and the recorded video of the Demo video that's on the TV for viewing/testing.

      Where should I look for faults? Everything else looks/works ok.

      BTW...have upgraded to the latest FW/SW version, but nothing changed....

      Philips 70PUS7855/12 bad colors when applying the tape fix on teh T-con board
      by silikon77
      Hi!
      Got an 70 inch Philips tv model 70pus7855/12 from scraps and I decidet to give it a go. I'm an enthusiast but no porfessional in the electronics.
      Found some advices watching youtube nad came up with this:
      It came with no picture, after diagnosing it I found out that the right side of the T.con board was faulty.
      I taped down the clock signals and I got a picture but the left side of the panel has less pronounced colours. Only the right 3rd side of the panel has good colors.
      See attached picture.

      I tried a few combinations to block individual clock...

      Samsung C32HG70 - Blown Ceramic Capacitor (CP813)
      by NuclearSpartan
      Hi everyone,

      I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.

      The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.

      I don't see any other visible damage anywhere else on the board....

      by rashidjafar
      I am looking for capacitor & Inductor values for my TOSHIBA Qosmio X500-110 - mobile graphics - Nvidia GTS 250M Laptop.

      Values for :-
      =========
      PC43 : Capacitor [3x1.5mm]
      PL7 : Inductor [2x1mm]
      PC39 : Capacitor [1x0.5mm]

      Any ideas would be appreciated.




      I can get Capacitor values from nearby components but wanted to know the max ratings also I dont have equipment to measure inductors....
