I am new to the forum and may be posting to the wrong area. I did do a search and it may be that I should be searching for a smaller set of numbers to identify it. I am a newbie into electronics repair as a hobby. Does anyone have a good source for obscure integrated circuits and component's in general. This is one of the 2 chips I am looking for. ab238p1n692-65e4. I think it could possibly a Bluetooth chip? I have a Bluetooth shower speaker the has less and less battery life. The Battery checks good. I wanted to replace the Leds with a non emitting diode or a resister, I to save the charge. I think 20 ohms should be sufficient. Just trying to figure out the circuit. I would appreciate any feedback

Hi
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6... -

I removed this chip with markings "14 8A SA4" between an HDMI port and a USB port that was faulty. I need to replace it, but I have not been able to properly identify this chip using the markings provided on the chip itself. If anyone is able to provide information regarding this chip, I would greatly appreciate it....Yesterday, 02:35 PM -

A: If you can`t read from it how do you expect to write to it ?.
Q: Why is my bios chip unreadable ?.
A: The programmer is faulty or has a worn or broken zif socket.
The USB cable is frayed,connector pins worn or some other physical damage.
Not enough amperage or voltage to power the programmer properly.

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
