Re: insignia p501q-10a MOSFET IDENTIFICATION
I think IC may have intermittent short.

Re: insignia p501q-10a MOSFET IDENTIFICATION
Replaced what I thought was a shorted IC, clicking on y main has slowed, but still there. Transformer is making the most clicking noise.Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
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.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Well Vset shouldn't be negative then. Are these generated on the PSU?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: insignia p501q-10a MOSFET IDENTIFICATION
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?Please do not PM me with questions! Questions via PM will not be answered.

Re: insignia p501q-10a MOSFET IDENTIFICATION
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?Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
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.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: insignia p501q-10a MOSFET IDENTIFICATION
Just wanted to drop a note that I just uploaded the SM for this set to tom's website
Hope it helps.

Hello,
Looking for an exact ID or fully compatible replacement for a dual N‑channel MOSFET used as a synchronous buck pair in a laptop charging stage. The package is the compact ~ 3×3 mm “dual” type where high‑side and low‑side FETs are integrated with a common SW node. The part sits right next to the buck inductor on the charger section. marked as 3840C 35039E. With these thermal pads, it looks like an onsemi NTTFD4D0N04HL or a part from AOS’s AONE family (DFN 3.3×3.3, 8‑pin options such as AONE36132, AONE36182, AONE36196, or AONE38132), but they are not pin‑to‑pin compatible.... -
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...09-27-2024, 03:31 AM -
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 ! -
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...
It is on the motherboard of an Asus ROG G513QY (Motherboard ref: G713-6050A3254002-MB-A01).
Thaks!
