by jetuaime81I have a nacon controller which has some fancy RGB ring (4 RGB LEDs). 3 of 4 leds are not good and I am looking for a replacement. The size I measured is 3mm x 2.5mm and it seems a 3528 led would fit fine, and it's in common anode. But I am not sure what wattage it is. I have attached photos of led and driver ic (ak63rq1 I think).
Also one of the triggers is malfunctioning sometimes, I don't know what these pots are called. I measured across the 1st and last legs (in circuit) seems to be 1.1kohm pot. I found some xbox controllers have this but they are 10k. Any info?...06-05-2024, 08:28 PM -
by x_orange90_xI got this tv yesterday and it shows a screen full of colored vertical bars and horizontal lines that move, change, and dance around. When the set is powered on there is a slight buzz from the tcon. I removed one ribbon at a time and this was the result:
Right side connected, left side disconnected = half image on right (somewhat distorted, see photo attached) white screen on left. NO buzzing from TCON
Left side connected, right side disconnected = right side black, left side white with distorted horizontal lines near top of screen. Buzzing from TCON

by EazyBoneI am extremely new to programming and dipping into this. I picked up a XGECU T48 Programmer and have the correct socket for EMMC.
I took the EMMC off a working main board with no problems and threw it into the programmer. I click analysis IC and it gives me a report (attached) of the current EMMC. Model H26M41204HPR
1) I manually found this chip(above model number) in the select IC section of the XGPRO 12.xx programmer software and it had a option for 4 bit and 1 bit. I chose 4... is this correct?

by Mark R"TQ" Subject at hand is a Marantz 120 tuner. The tuner lit up but no output. Recapped the entire unit. Before it was working fine tuning in Stereo and Mono. Now it just about tunes Stereo and some of the mono stations are weak. Nothing else was changed. When you do hit a stereo station the stereo lamp will come on but flickers as it's trying to hold the MPX signal.
I don't see how bringing the unit back with new caps checked by my Sencore LC103 would effect the FM section. Every Value is as it was from the factory?
Any Thoughts?-

by mrsithHi fellow lifesavers.
I have a Samsung washer-dryer WD80N645OOW which died mid-cycle. No response to anything, completely dead.
Checked the socket, the plug fuse, all good. Took it out to examine the boards.
There is a relay clicking on the mainboard. Upon applying power, I can see a diode flashing on inverter board, after a while a diode on main board lits up for a split second, then I can hear a relay clicking. This repeats a few times, then everything dies completely.
I've been trying to examine the main board, but it's a bit difficult becuse...4 Photos06-06-2024, 09:11 AM -
by ShadXoHi everyone,
I have a HP Elitebook 650 G9, where I made a dump.
I found on the internet that I need to edit the EC Bios. Something starting from Active till blank rows, which worked for a 840 G8 the guy was using, but didn't work for mine kept getting the 903-Computer Cover error.
It was worth a try and now i'm also stuck here after the 903 error it goes to the screen to enter the admin password.
I wonder if someone can help me with the edit of the dumps.

I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site [URL]https://starkeblog.com/lenovo/uefi/2022/08/28/extracting-bios-image-from-lenovo-update-exe.html[/URL], which are not working. According to those instructions, after issuing the command [CODE]"innoextract 7wcn38ww.exe"[/CODE] it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.

Just starting out in electronics repair and teaching myself as I go.
I have here a Corsair RM650 ATX PSU, which I'm treating as a learning project that if successful may be used in my PC.
Fuse was blown, probable power surge from lightning, followed the circuit and found, a dead relay and all the diodes and resistors around the bridge rectifier shorted. Rectifier and MOSFETs seem fine on the LCR.
Also found these tiny diodes on the other side, a few shorted, the rest seem fine. But they're not all marked as Zener on the pcb. So I'm unsure what these should be replaced with....Today, 09:52 AM -

I bought this MacBook brand new at launch. I have taken care of it since new and it suddenly failed on me recently.. it began to refuse to charge.
I first checked all the basic things before opening it, to no avail.
I have now opened it and taken the logic board out. I did a visual inspection and found no visible liquid damage or corrosion, or exploded caps, burnt components, etc. Cleaned the usb c connectors.
Here are my measurements thus far:
