Samsung QN50Q6DTA
Hi I just picked up a Samsung QN50Q6DTA. The issues was a 2 red flashes on the power button as the TV tried to turn on. Power supply OK. Backlight LED OK. If I remove the data cable from panel , sound is ON. I was able to identify the issue within one side of the panel. Used the tape fix and I placed the tape on 4 pins on one side of the flat cable. The TV ran great for 4 days and then the same problem appeared again...2 red flashes on the power button LED. Took the back panel off again and this time mode the tape on a different location and now the TV is running again. Am I missing something?... -
Flashing AM4 BIOS with CH341
Hi,
Is it impossible to flash Asus TUF B450M-Plus Gaming BIOS(25LB128D) with CH341? I have done it with H270N BIOS.
I used NeoProgrammer and selected 25LQ128C IC since 25LB128D is not in the chiplist.dat. I get no response from IC.
Any expert can help on setting up the import.xml so that I can import 25LB128D into chiplist.dat.
Thanks in advance. -

D865PERL has low 1.5 V
Hi, could anyone tell me where on this board is 1.5 V generated? Looking at it's reading from the monitoring chip, it seems to have dropped over time, and is often at 1.406 V, while the datasheets for the chipset say the minimum is -5% or 1.425 V, if I understand them correctly. Maybe this is the cause of ocassional crashes for me.

VBIOS for Acer Predator Helios 300 PH3-315
Dear Badcaps companions,
We got an Acer Predator Helios for repair that's missing the VBIOS chip (UV2). I already figured out that the chips is a Winbond W25Q16JWSSIQ so we're looking for a 2MB dump that's no where to be found.
The Acer website listst some VBIOS updates, but they are EXE files and they somehow seem to be compressed or encrypted. I have knowledge of BIOS but not much of VBIOS. Is there somebody out there that can help me?
