Anyone that could take a look at this?
Ive flashed the 8 Mb D96M-025.bin file , that has some data out of memory size, and machine does not even react to power button,
Flashed back the original backup posted earlier, the 64.9 kb zipped one, and machine turns on and no POST.
Anyone that could take a look at this?

Hey SMDFlea!
Thanks for the reply.
Yeah I also found it weird, but I desoldered the chip, its well detected in the tool and read it 5 times, all files are the same.
Backup is 4MB but compressed its only 64kb. Its indeed the content I have on the bios chip
Dont Think something can be done, cant find any dump for this POS system...

Hello friend!
I though about that but when I checked pics of the board , this mosfet is clearly different from the other 3.

Hey there
Thanks for the input! much appreciated
Yes its a dual mosfet I see 2 gate pins. But I cant find any schematic or a picture where I could identify it to replace and confirm if its a dead CPU or not..,
If the resistance is in the normal range values, at least I should try it out before putting it on the side for parts.
Has anyone a way to identify this mosfet?
Thanks !...Last edited by magneh; 02-16-2024, 06:18 AM.

HP Pavillion 15-EC - dead Ryzen CPU?
Hi there
Motherboard model : ag3hbmbcd0
Quick question for Ryzen specialists
Got this device without screen on a joblot and one of the CPU mosfets is missing.
This made me sad, as CPU is probably bad...
On that specific coil I have 1.8 Ohm (probes connected have 0.8) so basically 1ohm without the resistance probes.
On the 3 other coils 4.5 ohms.
I suppose the 1 ohm is too low, but I dont know the resistance of Ryzen 7 chips so if someone with more experience on these could give it the dead sentence, I apreciate...

HITACHI U50KA6150 LED TV - Turns on, BKLT ok, no picture
Hi there
Got this TV set to check.
HITACHI U50KA6150 LED TV
The tv turns on ok, I can see on my PC that it detects the screen and I can see it on the screen settings, but theres no image.
Backlight is present. screen not broken or shattered.
Its this clearly a TCON or panel issue?
I dont think it can be a board issue, but im not a TV expert
Any inputs but someone more experiences is welcome before I disassemble the device or try to find a new tcon.
Cheers

Re: Please I need bios for Asus FX705G
Sorry Vesko!
So the problem is that laptop sometimes work, or stays stuck in a bootloop when starting, with no POST.
Can someone help me fix the bios backup I uploaded earlier?

TX-65FZ800E - blinks 2 times red led no power
Hi there
I have this set with no power, blinks power led twice.
This seems to point out to D board issue
My first question is which one is the D board?
The main board?
Or one of the power boards?
Are they labeled with this? (did not checked the boards yet)
Thanks for any inputs...

Re: Acer Nitro 5 AN515-55-51QY - bios after PCH replacement
Thank you Vesko!
Machine does the same as with original bios.
Turns on perfectly fine, does the bios reset restart, and then caps lock activity, but no image.
I will leave the machine turned on see if the image comes up and ill update
I knew this would suck but Ill keep trying to get this machine alive...

Acer Nitro 5 AN515-55-51QY - bios after PCH replacement
Hi there!
Got this nice machine with 3 coils shorted.
Culprit, PCH.
I know these PCHs are tricky, they have programmable fuses if im not mistaken, and they are quite tricky to replace.
But I like challenges, so I ordered 2 new ones.
Replaced it, all resistance values got back to normal at the 3 shorted coils.
Machine turns on, caps lock responds, but no image on the screen.
Can someone help me building a clear ME version of my backup?
Much appreciated.

Re: HP Envy x360 15-ds0004nf 448.0gb16.0011
Hey
Several weeks back I took a look at this board again.
After replacing the SIO, I still dont get the white LED on the charger port.
I have 3.3V present , and also at the power button, but no reaction.
5V is not present.
Does anyone know if the white led should turn on even if the SIO is not programmed?
Thanks
