Hello everyone,
I am looking for a schematic of the netgear WN2500RP repeater.

it probably doesnt exist.
the datasheets for the chips may have example circuits though.

I found a schematic for the WNR200v3 so maybe it exists somewhere. I have already created a few subcircuits myself. Unfortunately, I can't identify a component that has broken (marking F42A 1K (1K crosswise)) . But that probably belongs in a different thread.
Furthermore, I have not yet found a data sheet for the broadcom bcm5358ub0kfbg chip.
Anyway, thanks for the answerComment

So here are the subcircuits that I created myself. Without guarantee. Among other things, Q3 is broken but so far I have not found out what kind of component it is (marking F42A 1K). Maybe someone here can help me.Attached FilesComment

Hi,
a guy told me the component Q3 is the AO6604 mosfet by A&O.
So I soldered the component in. There is now 1.2 V at the output (pins 4+6). Unfortunately, the extender is still not working correctly. The diodes light up as follows (all continuous):
D909, WPS: off
D904, 903, 902, 901, LAN ports: green
D910, connection to WLAN device: green
D916, Link Rate 5 GHz: red
D907, Link Rate 5 GHz: off
D915, Link Rate 2.4 GHz: red
D905, Link Rate 2.4 GHz: orange+green
D906, Power: orange
A button reset does not change anything.
So the troubleshooting goes into the next round.

Have you connected a serial console ? It should be J41 on your pictureComment
-
No, I haven't done that yet, but I will. What exactly can I do with it then? I have little experience with the serial interface/debugging.Comment

You can see if the firmware is running. That would confirm the circuit part is correct, and maybe show some messages of corrupt firmware. Or the thing may be stopping at the bootloader due to said firmware corruption. From the console it is possible ( not always, but many times ) to reflash firmware in this case.Comment

Ok thx. I have connected my PL2303 TTL USB adapter (GND, Rx, Tx) but I have not seen any messages. Neither with screen, nor with putty or minicom. I also tried with different baud rates and with Rx and Tx swapped at one end ;/
So there's probably something else wrong and/or Q3 is a different component, although the 1.2 V output voltage makes sense in my opinion.
Maybe JTAG level will give me some information? I could give it a tryComment

Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:
The schematic... -
Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Please help, i need schematic diagram for Dell inspiron 3537 board LA-9982P rev 3.0 (A02). Specific for A02.
I have a one beep with no display problem. Did reprogrammed the bios but no luck. i tried to troubleshoot using rev 3.0 (A08) version schematic and boardview but there's components/rails in the schematic that is none in my actual board, this is why I'm having problem checking every power rail needed if ok. attached is the photo of my actual board.
I'm not sure if A02 and A08 is really different schematic version from each other, but I have to try.... -
Iam looking for a Evga Gtx 780 schematic and board view.
The 780 possidon board view is not close.
Dicky96 has the schematic that would help. I seen a video on YouTube that he was working on gtx 780. If he could post the schematic that would help alot.
Thanks.01-10-2025, 01:58 PM -
