Hey everyone, I have a Sony Xbox-65x900e with static lines. I’m assuming either the panel or t-con. Any suggestions before I start diagnosing? Service manual says T-con, panel, or B* Board (which I have no idea what that is)...Today, 11:48 AM

Hello everyone,
I have an ASUS Vivobook 14 OLED M3401QA which is not posting. Currently when plugged into power/turned on the power indicator will illuminate and the battery indicator will flash white roughly once every 3 seconds. Leading up to this it would sometimes turn on and then other times not turn on, furthermore it also showed a screen saying "new cpu installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed" and then a screen telling me to recover the bios however it is no longer even posting at this stage.
The diagnostics steps I have attempted...05-25-2024, 02:34 PM -
I get backlights that stay on not there is no image. The tv does not automatically power on when plugged in either which I generally see happen when there is a fault. It responds as it should to the power button.
I checked the test points on the TCON and I have proper voltages except for at 1P15V. I don't know if that is supposed to be 15V or 5V, but either way I only get 1.134V on that point. I have 12V, 8V, VCC, and a small amount on the CKV point.
I tried heating up the SoC on the main board but that made no difference. Disconnecting either ribbon from the TCON also...Today, 08:55 PM -

I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...05-17-2024, 03:34 PM

Hi all,
First off, this forum really helped me out by advising me to cut some ribbon connectors to the LCD panel in order to fix a 70" TV (lots of threads on Sharp TVs with this issue). I didn't believe that it could work, but it did.
Now I've been encouraged to try to diagnose something quite a bit more complicated. That is an old T430 motherboard. I work on a college campus so I have access to pretty decent tools. I found the schematic for the motherboard on the site, and have been following traces and taking DC measurements from things. I also don't mind...Today, 03:27 PM -

Hello all,
I just finished flashing a new bios on an HP EliteBook 650 G10, and everything works except wifi and bluetooth. After installing the necessary drivers, the wireless card reports code 43 in windows. When restarting the computer, i get a code 10 (could not start) on the wireless card in device manager. I suspect that this could be a mac address issue, but I don't know what address to set it to in the bios, or if this is even related to the problem at all. Any insight on this would be appreciated.05-30-2024, 04:05 PM

Hi all,
Model: HP Pavilion 14-ce3010nh 8BV97EA
Board number: DAG7ALMB8C0 - G7AL REV C
Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck
I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....05-30-2024, 04:10 AM -
Hello everyone,
My Legion 5 15IAH7 won't post. won't boot. No fans, no keyboard backlight.
Online power led and charging led lights up.
My guess is that there is some issue with the BIOS.
It's the NM-E241 Rev 1.0 motherboard.
As I found out there are two BIOS dumps needed for this board.
One 16MB and one 8MB.
I've got both uploaded. Can you maybe check and fix this BIOS files?
Thanks a lot in advantage
