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...

Hello everybody,
I have seen a lot of posts about the A2237/A2338 about the 5V not boosting up to 20V issue, but none of them seem to have the exact problem as my board does.
My PPBUS_AON was measuring ~9.32V and the board kept power cycling, so I removed the fuse F5200 to measure PPVBAT_AON_CHGR_REG and indeed it was still 9.32V, but the board stopped power cycling. Then I measured U5200 values and got this:
U5200:
PPDCIN_AON_CHGR_R = 5.144V
AUX_DET = 1.287V
VDD = 2.767V
VDDP = 2.767V
AUX_OK = 0.848V
AMON = 0V
BMON...Today, 12:00 PM -

Hi, I have replaced a IT8176 in a Lenovo nm-d281 motherboard, and need to know how to program this keyboard controller.
The initial problem was an erratic behavior of numeric key pad, due to one of the IT8176 keyboard pins was shorted to gnd.
Now it completely doesn't work. I tried to R/W new chip with Vertyanov programmer but don't know which pin of the 34 pin keyboard connector have to be connected.
Does somebody know how it should be connected to Vertyanov or Svod programmer?...Today, 01:31 PM -
Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.

I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
Obviously the same LVDS connector for the screen connection...Today, 03:27 AM -
