Hi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.
For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... . Do not shut down to prevent... -
Hello,
I have a problem on a DELL E7240, LA-9431P motherboard (rev 1.0).
This is a laptop that I recovered, it had liquid dammage and had corrupted bios.
I reprogrammed bios + ec (v A.29 ME Clear)
I cleaned everything, after reassembly, it boots and it smells like burnt after a few seconds ... I disassembly the motherboard and see that the Power Management chip (in attached photo) has burnt!
It's the P800 chip on the schematic repair, and suddenly I can no longer read the info on the chip, if someone can direct me to avoid having to buy a used motherboard and... -
Help please with identification of few components for troubleshooting (Solar Water Fountain circuit)Need some help please with a few components on this small board so that I can troubleshoot the circuit.
The PCB is a Single sided board fairly simple circuitry has a +ve and -ve Solar cell power input, a 7.4v 1500mAh (dual 18630 cell) power in which the Solar panel charges the cells, and lastly the Output goes to a DC connector...
J1 is actually 1P1T Switch (in ON position completes Battery cell circuit
J2 - to DC Output
J3 is Battery cell connector
however I am struggling to identify if:
Y1 (SOT-23) are NPN Transistors, MOSFET's or 11v Zener's.... -
Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .

I mistakely pluged 100v japanese retro game console to 220v outlet.
So It seems that glass fuse and varistor have been blew up.
I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
Is there any way to identify varistor type in my sega saturn PSU?
Any reply would be appreciated.
EDIT:
It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage...
