Hi!
I'm looking for the Boardfile for the HuaQin NB2672 PCBA (Acer Swift 3X S3X SF314-510G), specifically the Allegro .brd of it and not the .cad.
Attached the schematic of it in case anyone needs that.
Cheers,...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

by 90NinetySo I purchased a faulty GPU on ebay Palit RTX 3060 .. It had a broken fan ( it did not spin at all )
Long story short , is the PWM control of the Card seems to be intermittantly faulty
Long story
I replaced said fan , seemed to work for a while , until randomly the fan starts spinning at 100% ( around 3.2K RPM ) for no rational reason ( temps and performance are ok ) . Now fan spins , though several times a day the fan decides to run at 100% for several minuites a time .. Then resumes normal operating ..
bear in Mind the card can be cooled sufficiently...Yesterday, 02:30 PM -

by JoeFlashHi! I have a TV, Samsung ue49ku6100kxxu, no boot, when connect the power cord, standby led and the backlight up and down repeated. When i disconnect the MB, the backlight is up.
I take some measurement and all ok. I have already try tape method and same happen, if I disconnect both flex from mainboard to panel tv same happened. This is a software error?
I have an IC programmer: CH341A

What Can I Do To Get Brighter Image...04-27-2024, 06:42 PM -
by unimatrix93Dear forum, I would like to ask some help identifying the backlight circuits resistors to limit the ampere to the backlight leds.
The power supply is a BN44-00852 and I want to decrease the backlight to increase the lifetime of the LEDs.
The TV is pretty much always on, used for CCTV cameras.
I suspecting R9838 -> R9841 resistors but I'm not sure. Thanks in advance!

by pc boyHi everyone. An HP X2 1012 G2 came the other day. The problem was that the device drained the battery while off. I checked and saw the current is 0.2 before start. I went and checked parts on the MB and saw that the JHL6340 IC that is responsible for controlling Type-C gets hot. Everything worked fine and I checked charging and data of type-C both were OK. I went ahead and replaced the JHL6340. Now it does not get hot, no current before start, charging is OK, but the data of type-c is lost. I mean any type-c device like flash memory or hdmi adapter etc. do not work. I tried another jhl6340 and...Today, 03:34 AM

by michdundeeHi 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

Trying to get a device for EMMC repair, and it's very difficult to lookup all the words to find if I'm on the right track lol.
Trying to reprogram EMMC on Sony/Hisense mainly but would like to hit a few other brands.
My question is would either of these work? And is there a specific card reader I need for TV emmc? There is like 10-40 additional pieces that I can get but not sure what I actually need for my application only.
I may do eeprom as well. Can someone point...04-21-2024, 08:18 AM
