Hello everyone,
I like to repair everything I can get my hands on.
A friend gave me a laptop that fell down while it was switched on.
Now the display remains dark and the laptop no longer boots up.
Since my English is not so good, I worked with a translation tool. Please excuse me if something is not translated correctly.
Normally this device is not in a price category where you have to grit your teeth, but I really want to find the error and learn something in the process

I am still new to this, so I might sound brainless/ignorant in parts of my description/questions, since I have a lot of gaps in my knowledge, but I will do my best.
The laptop is Lenovo Legion Y540-15IRH, and the motherboard model is NM-C221 Rev 2.0 (Schematics and BoardView can be easily found). To save time I have the exact problem in the laptop as the one shown in this video:

i’ve got a Asus laptop on my bench here with a shorted IC. I think its a Power regulator but i cannot find ANY info on this IC. I thought i’d try my luck here.
Had a coil which was shorted to ground. Injected 1V and watched this ic get hot under thermal cam. Removed the IC and the short was gone. Now its .3 voltage drop which is good.
So basically i need help identifying this IC.

Good evening, I've been stuck on a problem for a smidge now and not sure how to proceed..
Ps5 boots etc but just doesn't have any video .. put a new hdmi connector on and a new encoder.. and all the diode readings are good except
15- DDC clock - 671 - Iam getting 677
16- ddc data - 671 -iam getting 677
And hot plug (19) is 695 when should be 686..
Any ideas on what could cause this ? I have no knowledge of hdmi signals or EDM 033 board view to track where they go etc ..

I have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.
When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...05-08-2024, 01:30 PM -

For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...03-20-2024, 07:29 AM
