Re: Corsair SP2500 parts information required
Sorry for the late reply, little busy at the moment (more repairs coming in again). Have not gone back to the speaker yet (although all the parts ordered have arrived). Mind enlightening us on the shorted part/component found?

Re: Corsair SP2500 parts information required
Hey could any of you tell me the value of R293 mines completely blackened, also if any one has the part number for the unlabelled 8 pin IC on the SMD side that'd be awesome.Comment

Re: Corsair SP2500 parts information required
Couldn't find R293 on board.
R930 def 10K.Mine has taken out R921 and R922 and R930 if anyone has the values of R921 and R922.Also C934 has blown and R not sure what number but next to C967
on the top side which is second one along from IC.
Audio board looks fine.Last Corsair product I ever buy

Re: Corsair SP2500 parts information required
Hi everyone.
My Sp2500's PSU partially died.
the small part that powers the pod is working.
But the part tha powers the amps is dead. ( 3 blowed caps, 2 or 3 dead resistances.)
Since i don't have the equipment required to repair it, i think that i'll buy another PSU in parallel. But I don't know the voltage of the 4 pin. there is 3 inscriprions next to it : VCC GND and CN904.
Thanks a lot,
NicolasComment

Re: Corsair SP2500 parts information required
I've had the PSU board of a Corsair SP2500 handed to me for repair. The 3843GM-E1 has died with one of the legs (pin 3) having had the track lift from the heat of the failure, along with three resistors (two large, one small) that died on the other side of the board.
From looking at photos of other SP2500 boards in various stages of death, I have worked out that the possible values for the two large resistors are 0.22 Ohm and 56 Ohm, with the two smaller resistors being rated at 1k Ohm and 220k Ohm.
Can someone please confirm these values, along with providing possible sources for the 3843GM-E1?
This design of PSU by Corsair doesn't appear to be up to the job. I've seen lots of boards with exactly the same failures and the lack of an earth pin on the Euro socket worries me. it's either bad design or poor components (or both).Comment

Re: Corsair SP2500 parts information required
uc3843 should be at farnell
not sure what the gm-e1 meansComment

Re: Corsair SP2500 parts information required
The chip has GM marked on it after the 3843. The -E1 was added by some Google searches. It's the right current mode PWM controller though.
On this board, it's the current sense line to pin 3 that has fried and taken the chip with it. What is bothering me now is what caused the current surge, that fried the track?Comment

Re: Corsair SP2500 parts information required
maybe the chip shorted.
any time one of the 384x series dies btw, replace the related startup and smoothing caps.
a lot of the older controllers like 3842/3 and TOP series can blow if the startup fails from poor caps.Comment

Hello Community,
i'm troubleshooting this one since days and actually i'm really lost because i believe i'm Missing the required experience for an issue Like this...
It is a Dell XPS 15 9560, i7-7700HQ, GTX1050 Board Number LA-E331P Rev 1.0, Most similar to LA-C361P so i use this Schematics.
Issue: Starts and shuts Off after a few Seconds. Basic Troubleshooting (Adapter,RAM,BIOS/EC Flash from alisaler) of course already done, which didn't Changed anything.
I have another working Board with i5-7300HQ and GTX1050, with It's Help i can compare... -
hi all,
first of all: i'm a (motivated) newbie, so please forgive me any stupid question i may or may not ask
i'm currently repairing a projector: Epson EB-U42 that doesn't start (no lights, nothing).
what i've found so far:
- the PSU does its job and supplies 12V to the mainboard via the connector.
- shortly thereafter, there is a mosfet (TS420-600B) where i can test 12V on the one side (in the data sheet this side is called Anode), Gate 0V, Kathode shorted to ground
- not far away, there's the first cap with a resistance of 0.7 ohms.... -
The TV is a Samsung UN65JU67ODFXZA Version TD01. I replaced the power source board and the TV is now working, but I decided to try and troubleshoot the old board to fix at the component level. Trying to get a schematic and a parts list has proven to be an issue. Trying on my own, I can't tell you how many times my Norton security has flagged sites as "malicious". I ordered a service manual from ServiceManuals.net, paid $16.99 and got 66 pages of everything BUT schematics and component parts list! Can anyone steer me in the right direction? Some of the surface mounted component parts... -
Hello everyone,
I'm encountering a frustrating issue with my Corsair SFX 450 power supply. After an undefined period of operation, my PC will either suddenly restart or, in some cases, it won't start at all until I disconnect the power cable and reconnect it. This erratic behavior occurs intermittently, making it difficult to pinpoint the exact conditions under which it happens.
For context, I have tested the PSU using an electronic load at 150W, and under those controlled conditions, it functions flawlessly. This leads me to... -
Hi all! I'm a newbie to to the forum and electronics repair in general.
I picked up a nonfunctional ASRock Taichi X570 motherboard that someone threw away. My main goal is it to repair and use it. But even if it's not possible, I'd like to learn about the process.
I'd very much appreciate some guidance.
Here are the steps I've taken to diagnose the board:
I first tried powering the board without a CPU or memory. The lights turned on. As you'd expect, the board wouldn't boot.
Hoping the board worked, I bought a compatible CPU on amazon. I wanted...
