    Repair on powercolour Hd7950 3GB

    I received a power colour Hd7950 3Gb GPU.
    Diagnostic card stuck at b2 and cannot cross it. So not output screen.
    On board graphics also do not have output.

    I measure all the voltages, the core gpu ( I forgot is technical name) voltage rise and fall to 0V. the rest of the voltages are fine.

    How to troubleshoot this type of problem. the PWM chip is working and enable voltage is there , so that is why there is a rise in voltage.

      Does it detect as a secondary card?

          No it does not detect at all. Basically the voltage did not appear also, So i think it is go back to basic to check circuits.

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              Panasonic TH-L42D25A checking the PSU output voltage
              by electron_jj
              Hi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.

              I have been inspecting and testing the capacitors and diodes in the power supply board to try to...

              Trip light 2400 watt line conditioner bought used issue with low voltage oscillation going on between relays
              by sam_sam_sam
              I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them

              The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

              Now...

              Powersupply has all the voltages - Monitor still no power
              by Capacitorial
              Hello guys,

              I have a Philips 240B7QPJEB. The monitor seems completely dead.
              I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
              On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
              The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
              The weird thing is, that the Power LED is powered over the TCON board.
              On The TCON...

              3+1 Voltage Regulator for IMVP-7/VR12 CPUs

              Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
              core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
              configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
              serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.
              Based on Intersil's Robust Ripple Regulator...
