I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them
The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

Hi,
as noobie to this please excuse my lack of experience.
I am trying to remove a BIOS password from this machine:
[B]HP ProDesk 400 G6 Mini [/B]
but so far I still have no success.
I bought [B]CH341 programmer[/B] and decided to give it a try.
The programmer came with [B]8 pin [/B]cables and connectors or whatever everything else is called so I had to buy a new [B]16 pin cable[/B] because the chip which I think is the BIOS is with [B]16 pins[/B]..

Hi
I have an ROG MAXIMUS XII HERO (WI-FI) board with demaged PWM controller ASP1405I, and this is unfortunalely a programmable chip.
Without programming it, it won't start to work on the board - have checked this physically with a new unprogrammed chip.
I'm looking for information about the possibility to readout and program the ASUS PWM chip ASP1405I again with the firmware (configuration file).
To do this, it is necessary to buy a quite expensive I2C type interface card (named USB005), so I'm wondering if it is worth to spend the money, as this makes...06-03-2024, 10:50 AM -

Most Displays I have worked with are of course LCD Or Blueish Fluorescent Types. I Have a Marantz PMD800 tuner with sort of a white display. The display area is a sealed rectangular shape in a Glass Case. Looks like some sort L.E.D. display only not your typical section number type. I picked up this Tuner cheap as the display is very Dim. In front of the circuit is a dull red Plastic lens.
The display is very week and hard to see. I've got my DC 5 Volts allover and also a DC 32 Volt that runs some other section. Power supply looks good front to back. Not familiar with this type...06-07-2024, 07:19 PM -

Hey guys! I've recently found out this amazing forum where people talk and discuss about electronics repairs and i'm actually amazed with everything that here's have to offer.
Oh well, i came here looking for a simple bios file in order to get my main laptop working again, but after a while trying to figure out what the hell was going on, i'm quite concerned that it would be worse than i tought. I was fooling around with Mr. Smokeless's UMAF BIOS mod, looking for a way to enable CSM compatibility and legacy boot on my device.

I am still working on an Lenovo e14 AMD notebook with some problems. The laptop booted normally but had a ton of problems with the soldered ddr4 memory. I tried deactivating the memory via bios, but that didn't work.
As i have a matching donor here, I decided to change the module i suspect to be faulty and exchange it with one of the donors.
Did so, but now the laptop won't boot anymore.
Anyone here who already did that and can comfirn, that exchangeing one module alone would work? Or do I need to exchange all 4 of them to make it work?Today, 02:42 AM -

Hello guys, can someone help me with an eMMC dump for a Sony KDL55W-955B TV, I tried to read the original memory with the RT809H but it shows me that it only has 1888MB even though it should have around 3.8GB.
