I got a 15-IIL05 that failed to turn on BUT IT DID TRY TO TURN ON and then turned off after 30+- seconds, i disassembled it and found a screw loose inside the case.
With charger it turns on, fan spins but gives no image.
Tested main mosfets no short, tested 3.3v,5v,DRAM, CPU etc and they were present.
Reflashed BIOS, same problem.
Replaced both main mosfets.
Checked main mosfets again and i noticed that they closed once the laptop shut down, so i decided to bypass them and used a bench PSU to check how much power the laptop was drawing while trying to turn on, 20v@3A,... -
Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Hellow guys , i really need your help here.
Lately i have a problem with My TL 866 II Plus programmer, and to be more specific many times on various IC ( Winbond, Gigadevice Mx) i get Check ID Error while i am trying to read the IC. Has already been detected without any kind of problem, but the only to read them is to uncheck every time the "Check ID " option. After that i can read it erase it and re-program it only to get another error at then end saying that can not verify the programing went well so i have program failed. So i am trying to find out what is going on? I... -
So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0. I already tried two CH341A, already did the 3.3v fix mod, using AsProgrammer, NeoProgrammer, Colibri, and CH341A 1.29. But the problem still occurred. What I did wrong here? Can anyone help me? Thanks in advance. Here is the log in Colibri :
