by tommy97Hi,
we've got iMac Pro 2017 which having a problem with SSD, iMac come with 2 SSD's 1TB, it was having a problem with the SSD so we get the replacement, installed in and iMac is stuck in recovery mode, tried to restore it & revive, nothing worked - error 4010. After installing old drives now we're having the same problem that the device is in recovery mode. Previously after swap of the SSD iMac worked on the old SSD however after attempt of revive on the new SSD machine stuck in recovery mode, I can go to DFU but the same result with error 4010.

by MegaZACHi all!
The laptop has no signs of life at all. The only thing showing any voltage is the BIOS battery. Nothing is heating, nothing takes any charges, no LEDs blink, no reaction on power button. My USB-C meter shows nothing taken, however it starts detecting voltage only above 3.7V.
These boards have notorious USB-PD chips. I can't even measure what's on their pins because they are just a fraction of mm in size. What I suspect are these chips:
1) 5457V K8K33H2 GK34CC
2) RT3663BM GOW 7K834
3) Lenovo IT8227E-256 2106-CXA Z0043B

by ryogadan78Hi guys, I have this 2011 iMac A1311 with a strange problem.
Most of the time, when I plug in the power cord, the first of the 4 LED's turn on, but when I press the power switch the LED turns off and iMac won't boot up.
Sometimes, when I unplug and plug the power cord back in, iMac starts up correctly by turning on the 4 LEDs in sequence.
I have already tried a new power supply, but the result does not change. Do you have any suggestions?

by jord4231Looking for a replacement for this. It's in the 3.3v standby section.
I think it reads GA6
I could be an A6 switching diode but I'm not sure because pin 2 is connected.

by chth96When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.

by nobbnobb1I am trying to get a set of Creative T40 computer speakers to work again of which I believe the problem is bad caps (470uF @ 35V). So I get a generic set off Aliexpress. The brands are meaningless, but if anyone cares it's a "Chongx"
When they arrive, to my surprise it's much smaller than the originals. These are 8mm x 15mm whereas the OE is 10mm x 20mm. Unfortunately my meter does not test capacitance but I'm guessing there's no way this meets spec at 80% the size.
Thoughts? Is it still worthwhile or safe to try and install these to see if...-

Hi All,
Laptop: ASUS F15 TUF Dash FX517ZC-HN114W
Context: When I was out the house my partner hard shutdown laptop while BIOS was updating, so my son has no working laptop now. Also as a result I know the BIOS on the chip is messed up so I can’t extract it using the ch341a and use it to perform the method explained on site to modify an update downloaded from the ASUS website to get the BIN to flash.
If anyone can help with a BIOS BIN/ROM file for this laptop, I would be forever in your debt! Thanks if you can help!
Assuming it is less than 2MB as...-

by mikkele86hello.
I came across this thing and im not sure what it is exactly, I have never seen such thing before.
I know it gotta be some kind of diode with Drain, Source and Gate1 and gate2
It resides in AM/FM module and im measuring 200ohm across D and S.

by unimatrix93Hello everyone,
I'm trying to fix a small LG TV with wierd issue.
So I check that the display is OK by fashing a lamp at the screen. LCD is okay OSD is showing up.
Now since the BL is dark, I disconneted the BL from the mainboard and I injected voltage to it with my blacklight tester.
The BL turns on, the tester shows around 80V. So the led strips are okay it seems.
Now I started to suspect the BL driver IC which is a MP3378.
I have a donor board (dead cpu) with the same IC, so I swapped the driver IC but it did not solve the issue.

by aaronkatriniHi all,
Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.
Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...04-18-2024, 03:15 PM -
by norbiszokeHello,
We have this set here in our shop that is not ginving sign of life besides red light that is blinking one time after pressing the button and nothing more... After detaching the mainboard from the PSU (this set has separate board thank god?! or not...) the backlight comes on. After reattaching nothing besides red light.... Can anyone from the forum help me here? Thank you in advance. Here's a link with images of the mainboard and the memory IC's that are on it.
