Re: insignia p501q-10a MOSFET IDENTIFICATION
You can usually just unscrew them then desolder them, no need to remove the heatsink.

Re: insignia p501q-10a MOSFET IDENTIFICATION
Okay replaced all shorted components on board, no more vs short to ground pins. Plasma now powers up fully, but now have a clicking sound coming from the middle of the sustain? What would click? Relay?Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
TV works fine? But you are hearing a buzzing sound? Or is it a clicking sound definitely like a relay? Continuous or intermittent? Once on power up, or all the time?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
Im sorry for the bad summary, it is powering up, but just get a very brief flash of the screen then goes dark. And then a continous clicking starts on the y board, there is no ipm modules to fail on this board. Va,Vs measure steady at the pins.Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
IPMs are replaced with MOSFETs on this, there's no real difference between the two, except the IPM fails as a whole device whereas individual MOSFETs usually fail.
How often is the clicking? Few times a second? Ten times a second? Once a minute?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Roughly 3 times per second. Its pretty fastComment

Re: insignia p501q-10a MOSFET IDENTIFICATION
Use a toilet roll tube or similar cardboard instrument to locate the clicking source. It's most likely from that yellow transformer, or the inductors near the bottom of the board.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
Toilet paper roll Idea was spot on!! I found a 20 leg #IRS219565 is what I think is clicking. What is it, what does it do?Comment

Please post a clear picture of the area of the board where you think the clicking is coming from.Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
This is the best picture I can get, the little black IC right of the blue cap is what I beleive is clicking.Attached FilesComment

Re: insignia p501q-10a MOSFET IDENTIFICATION
That is a gate driver IC. That could be clicking if the FET near it is shorted.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

The fet direct right of it is not showing a short, is there a way to test it with power being applied while tv is running?Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
3-4 of the mini brown rectangle fuses are showing shorted around that area. I cant believe that they are though.Last edited by topfli8979; 12-23-2012, 12:35 PM.Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
Fuses are pieces of wire, so they should read short when OK.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
Further searching, led me to find a yellow transformer on the upper half of board is clicking in sync with the gate ic, is this part easily replaced?Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
It doesn't usually fail, that's just a symptom of a shorted output. You need to trace where the output is shorted.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
Tom66, tracing from the clicking gate driver ic, it goes into the heat sink, but none of the 3 FETS are shorted in circuit. Could one be on the way out, not allowing full voltage through itself?Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
There could be a gate-drain short, or the driver IC could be damaged.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
pin 10 on top to pin 1 on bottom is only short I can find on the ic, all the rest seem okay. Im starting to see why these boards are so expensive to replace, its driving me crazy!Last edited by topfli8979; 12-29-2012, 04:25 PM.Comment

Re: insignia p501q-10a MOSFET IDENTIFICATION
I pulled the closest FET to the right of the driver IC, clicking is still there, so problem is probably before IC?Comment

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!
