    I think IC may have intermittent short.

      Replaced what I thought was a shorted IC, clicking on y main has slowed, but still there. Transformer is making the most clicking noise.

        May be a short on VSET/VSCAN line, I think that transformer is for generating VSET power and VSCAN power. Check both of those voltages.

          vscan -192.7, vset -44. Sticker says vscan -193, vset +88

            Well Vset shouldn't be negative then. Are these generated on the PSU?

              VS,VA,VG is all that comes from power supply.

                I would expect the capacitor on Vset output to burst if that were the case though. And it would make a very nice bang. Perhaps it is relative to another rail; is there a resistor or other component marked "Vset" that you can measure across?

                  only a couple small fuses, measuring 14 volts.

                    I have a samsung 50 plasma, with panel #S50H-YB04, this insignia panel has #S50H-YB03. Connections are Identical, just different layout of y main. Could I switch boards?

                      Can I see a picture of the different Y-main?

                      I would suspect possibly issues with the controller board, so I'd swap the buffers, X-main, Y-main and control simultaneously.

                      You'd need to adjust the Vs/Va/Vset/Vscan/Ve and Yrr/Yfr to their correct values.

                        Just wanted to drop a note that I just uploaded the SM for this set to tom's website Hope it helps.

                            Here is that other ymain off the samsung plasma. Also added original insignia y main to compare.

                                I tried to use this method:

                                Testing an N-channel MOSFET:

                                Step 1: Discharge the Gate (turn off the MOSFET)
                                Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
                                Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

                                Step 2: Charge the Gate (turn on the MOSFET)
                                Now, place the red probe on the Gate (G) and the black probe on the

                                Hello,

                                My Asus monitor stop working today !! I found the problem on the main board, the power supply board is ok. It's Q9, a mosfet but I have no idea what are the specs since I don't have the schematic for that monitor !!

                                Can someone help me identified this mosfet ?

                                Thank you !

                                by Nooy
                                Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:

                                I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet...

                                Hi Guys, I'm trying to identify that mosfet to replace it. Any help would be appreciated. I've checked the IC Markings and Datasheet section but I can't match the brand logo with any of the pictures. I thought maybe Alpha Omega because of the greek symboles or maybe Sinopower as the logo vaguely looks like an S...
