Hi,
First post...
I have this TV, which was working, then suddenly would not turn on. It would get the clicking relay then flash up the screen for less than a second, off for a second then on again. Removing the plug the relay continues to click on and off for a few cycles, which I don't think it did before.
Left it a few months, then finally got round to taking the back off, and it worked as it should. So I tested various bits and all was well. Then turned it on again, and back to the clicking relay.
I disconnected the main board from the power...02-06-2025, 08:42 AM -
The board is LA-F411P ,DELL 5590 ...
The screen polarises,no backlight,no image,only black screen,tried another screen,the same,so there is no backlight,but there should be an image when i shine a lamp behind the screen,but there is none...only dark screen...when screen is connected and i press F8 to turn the image over to the external monitor, the external monitor gets coloured bars ,but when i disconnect the cable from the EDP ,the HDMI picture is good...What could be the problem? I don't have another edp cable, but i measured it with meter and it comes out good...i am baffled......Today, 03:08 PM -

Hello, I have a problem with starting my laptop. I got a laptop that doesn't start. It turned out that it was flooded with liquid. I removed the corrosion, replaced the damaged elements and the laptop started. Before I understood what the problem was, I uploaded a new BIOS with a clean ME region downloaded from this forum. The laptop started and worked. However, I decided to upload the original BIOS back. I cleared the ME REGION in it and uploaded it to the chip. After this procedure, the laptop stopped starting. It uses 6 watts constantly without any changes. Also, uploading back the BIOS with...02-14-2025, 03:11 PM

Hi,
Recently I gave a shot at recapping this Excellent power IT ATX 300 lc clone doohickey PSU. After I replaced all bulging caps and the 47uF 50v in 5vsb I turned it on. 5vsb and ps_on are spot on. So I shorted the ps_on and it dies after a split second. 5vsb still is generating, all other lines also generate voltage for a while but they all discharge so fast.
Now I am sure this isn't a problem with the 5vsb damaging the PWM IC or BJT circuit, but I have no idea where to go next. Maybe replacing all the smaller caps?02-04-2025, 12:56 AM -
I am working on a Dell precision 3560 with a locked BIOS. I used AsProgrammer software with the CH341A v1.7 set at 3.3V. AsProgrammer is the only software that works with the CH341A that lists the W25R256JV. Reading the 25R256JV with this setup returned garbage results. I switched to my T48 programmer and it identified the chip as a 25Q256JV and appeared to read the chip perfectly.
I need to reprogram the chip but I am not sure if the programming the 25R256JV with the 25Q256JV setting will work. I don't want to risk bricking the computer.
Anybody have any experience or...Today, 09:21 AM -
Hello,
Laptop Asus Zenbook UX435EAL ; s/n: m8n0cx15h989339.
It turns on but no image appears, maybe the bios got scared.
Maybe someone has a working dump?

Hello,
I'm hoping someone could help me confirm if I have identified the following parts correctly.
Apparently the DP cable became stuck inside the graphics card and was yanked out. This caused some sort of short which burned the DP contacts and blew some resistors and ferrite beads.
The parts needing replacement are on the back of the board behind the HDMI input.
I have identified the parts as the following:
C6037: MLCC 0.1uf/16v(0402)x7R W05
R6016: RES 499 OHM 1/16W (0402) 1%

I have a battery operated tab welder and the battery does not have enough current for the battery tab welder because after about 30 welded it does not have the same current output it voltage has gone down by at least 0.500 volts or maybe a more than that
I can fit 21700 battery cells in the enclosure it is very tight fit for four of them that are 35 amp high current capacity 35X4=140 high current output this should work a lot better than what is installed right now
I tested the battery cells there are installed right now and they are testing good with no issues that I...02-04-2025, 08:08 PM
