Quick repair summary for those interested. I had a Hisense 58R6E3 TV that had backlights working but no picture. T-Con had 12V supply but some of the supplies on the board were 0V. Unplugging one of flat cables to the LCD display driver boards brought the supplies back up, so I figured it was a short on the LCD panel driver board. Narrowed the short down to the 15V power supply by checking the coils on the T-Con board to ground with a diode test and confirmed that all the MLCC caps on that rail all showed a short to ground. I injected 5V/1A into the 15V rail on the driver board (T-Con disconnected)...Today, 04:16 PM

I found my old Xbox 360 in storage and opened it up to see if there was anything that broke since it was built in 2006 (launch era Xenon revision, never red ringed, never been serviced) and didn't want to find out by releasing magic smoke. Upon moving the dust bunnies out of the way I was greeted by a bunch of capacitors with crud coming out of the top; it doesn't seem to have leaked onto the board so at least I have that going for me.

Hi 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...Yesterday, 09:11 AM -

I am trying to determine what these components are, used a jumpers. I am not sure if they are ferrite or something else. Board ID is EU-KFR80W/BP3(IR311+PS21997+SIM6822+LOCK).D.13.WP2-1. A service tech shorted the area underneath these components, which were covered in carbon. They are also used in another place on this pcb but I'm not sure what they are. I have not removed them to measure yet. They do not have a label on them.Today, 01:28 PM

Hi, this is for troubleshooting and, hopefully, repairing a Delta Power psu
that is still quite new, as it worked OK for some months until it failed.
At the time I was not into power supply electronics; it was put
aside and a new power supply installed inside the computer. Also at the time
power supplies were half the price of today's.
On the PCB there are a D339 and 7500B chips.
I have found that schematics with these 2 chips (see included file).
Does it represent the actual circuit of the MAX-500ATX, I cannot tell.
Some measurements,...06-05-2024, 03:34 PM -
Hi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.

I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...05-17-2024, 03:34 PM

Hi,
i had a HP 640 G8 with a DA0X8AMB8E0 Board. I would Flash the BIOS, but i used a CH341A Programmer with 5V instead auf 3,3. Then I thought the BIOS was now defective. I have already replaced it with a new one (flashed the same BIOS).
With the new chip, the notebook has the same error. The charging port lights up once and then goes out again. The notebook does nothing more.
I iced the board with a cooling spray to possibly find a chip that gets hot or has a short circuit. Unfortunately, I didn't find any. I suspect a fuse might have blown. Does anyone...Today, 02:47 AM -
