Hy guys, i have this Audi smart key with a touch screen not working, the key has a 450 mA battery inside that looks ok on the multimeter, but when connecting the usb c on the board there is no power consumption, no current going to the board. Has anyone worked on these before?...05-14-2024, 06:58 AM

Hi,
This board has slight water damages. No fan spin.
When I power on, I got:
PM_SLP_S4_L
PM_SLP_S5_L
PM_SLP_S3_L
ALL_SYS_PWRGD
all go to 3.3V, then back to 0V after 1s
PP5V_S5=5V
PP3V3_S5=3.3V
SMC_S4_WAKESRC_EN remains at 0V.
With SMC bypass, fan spins full speed.
Can you help on troubleshooting SMC_S4_WAKESRC_EN missing?...Yesterday, 09:37 AM -
Hi,
I bought a faulty A2289 for myself.
The USB-C meter was stuck on 5V.
After remove the board the U3100 was corroded and also around but quite light.
So I clean the U3100 and see R2834 in bad condition and its value was not good.
I replace it and not the USB-C meter shows 20V, the fan is spinning, CPU is hot but nothing else no picture.
The USB-C meters shows a very low current with all connected. It starts at 20v few mA and then stays at 20v 100mA.
How mush current the board is supposed to take without nothing...05-19-2024, 12:20 AM -

Good morning I have a problem with my [B]Samsung UE49MU6120KXZT (Version 01)[/B] TV with Motherboard[B] BN94-12644A[/B].
After disconnection from 220V the TV remains switched off with status led off. I need information on how to proceed with reprogramming the flash memory and the BIN file to reprogram it.
I have purchased this programmer on Ebay: [B]CH341A EEPROM PROGRAMMER FLASH BIOS 24 25 SERIES + CLIP TEST[/B]. I include photos of the motherboard. I am not very experienced but I would like to learn so the more detailed the information, the better it will be for me...05-17-2024, 04:55 AM -

Hi,
I have an HP 255 G8 that runs for as long as its battery holds charge but won't accept AC power.
I have partially diagnosed the problem and the issue seems to be that there is no ACDRV output from the BQ24735 to turn on the two input MOSFETs. The 24735 has a VCC of 19.57 V, the ACDET input is at 2.93 V and the REGN 6V LDO is outputting 5.98 V, so everything looks good - but ACDRV is stuck at 28 mV.
I've already replaced the 24735 and both input MOSFETs and nothing has changed.
I'd appreciate some suiggestions as to what to try next.Yesterday, 08:45 AM -

Hi masters, anyone can help me with BIOS? Long story short, spilled unit, did not start at all. Found two burned resistors in 3.3/5V step down controler. Now unit start, but it takes 30-40 second to get a picture and than FANs start run at full speed and turn off after 20 seconds, so could be ME corrupted...
