Hi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.
BR,
Michele

Hello,
So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess
Its a ASUS P5VDZ-MX board.
I would really appreciate some assistance on what the best replacement caps would be for these:

Hi, I'm currently trying to diagnose a Gainward RTX 3060 12GB "Pegasus" that I bought as damaged. I know nothing of its prior history.
A boardview for an MSI model, which matches the board layout apart from some resistor values I saw, was already uploaded in the past if you'd like to have a look (I used file V397_70). See [URL="https://www.badcaps.net/filedata/fetch?id=2101580"]www.badcaps.net/filedata/fetch?id=2101580[/URL]

Hi, have a MSI motherboard 16J91 with no image and only consumes 22 mA when power on.
There is no voltage at pin 8 of bios chip in stand-by, but as soon as I push the power button, pin 8 and all other pins of bios voltage rises to 3 volts, but no pulses are present.
No voltage on PM_SLP_S5# or other PM_SLP.
KB9028Q has been replaced and programmed without any issues, but pulses in bios still missing. (measured with dso)
Can pch be blocking bios pulses?
Thanks for your help....Today, 12:48 PM -

Anyone is familiar with a TRIAC circuit?
I came across this schematic, and I built it, but I can't seem to figure it out why I'm getting a low AC voltage output at the TRIAC terminals.
With 230V AC hot side at the TRIAC MT2, I measured 60V AC between MT1 and neutral side when the comparator output LED indicator is on, and 20V AC when it is off.
Same result if 230V AC hot side is at MT1, and I measured between MT2 and neutral side.
My heating element doesn't work with 60V AC. It's not even getting hot and the thermocouple amplifier output is a...Today, 02:12 AM

I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.Today, 10:55 AM
