    what is this component?

    what is this component i took it off of a power supply on a sharp tv LC-37SB24U i downloaded the service manual but it doesnt have a component list and i am not getting any voltage to the big filter capacitor this seems to be on the primary side of transformer and i am getting 150vdc from the bridge rectifier

    this component does not have any resistance at all but has bands like a resistor but it is clear it is labled c7102

    it is labeld c7102 as all the other capacitors on the board are and the only capacitor codes i can find are for 4 band capacitors not 3 so how would i go about finding a replacment

      It looks like a gas arrestor like this, http://www.alibaba.com/product-detai...073513344.html

        That is GA7101 Gas discharge surge protection, the circuit does not need it to operate. C7102 is the small blue disk cap next to it.
        What DCV are you not getting at the connectors in the cold side of the circuit? Please up load good clear pictures of the whole board top side and the bottom side.

          Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
          by howardc64
          Failure Symptom



          No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

          Where is the short?

          Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



          Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

          85XT SAYA - Datasheet request
          by NunoRC89
          Hello everyone, i would like to request your help to identify one IC.
          It has only labled:

          85XT
          SAYA

          I want to know if theres a datasheet of it or there's any compatible model of ic part that could replace him and fit.

          Thanks in advance...

          Roland SPA-120 Amplifier Tech Notes / SM / Schematic Source?
          by KeyResults
          Repairing a Roland SPA-120 amplifier, a solid-state early-mid 80's part of the Roland Rack. The PCB is Labled AP-124B. Was thinking lytics would resolve the nasty output on scope but all tested 100% for values, ESR, and leakage (very surprised!). Symptom is nasty wave form on both channels in Stereo mode, but clean in single channel mono (BTL) mode. The Output transistors test ok at room temp, but still could be faulty once heated up. Anyway, a schematic and some test point voltages would sure save some time. Thx!

          Identifying a 3-legged device
          by Nevillet
          Hi All,

          I have a small Sony CD player (CMT-X3CD) where the PSU board has died but i'm having trouble identifining a fried 3 legged component labled as Q501 on the schematic. The marking on the device itself is terrible and all I can decifer is:
          25216
          SMK

          Can anyone suggest what it can be replaced with?

          I've attached the service manual and the PSU board can be found on page 36/7.

          Many thanks.

          A2251 (820-01949 board) PMU IC U7800 CALPE-PMU
          by duwane
          Hi All.

          I have an A2251 820-01949 board that has come to me for data recovery. Previous repair shop that worked on the board have removed the PMU as they said that the chip had a hole burned into it. I have replaced a bad cap that was causing a short on PP3V3_G3H_PMU_VDDMAIN to ground that I am 99% sure is what caused the PMU to blow. Now I am trying to find a replacement PMU chip U7800 (labled as "CALPE-PMU" in the schematic).

          I have several questions about the PMU chip itself:

          1) Does anyone know if these chips are identical between boards...
