Hello, so i got this asus fx516 for quite cheap, one of the numerous failures on it is the EC (3v ldo shorted), a bga ITE IT5125VG, so i went to aliexpress to the store i usually buy mosfets and other ics from and asked if they could sell me this ec programmed, and they say YES SURE, so i bought it, i sadly don't own an svod yet (I do this as a hobbie). And i was wondering, it's possible to program an ec outside the laptop? I've seen this done on a laptop through the keyboard connector and even the battery connector, but not outside, at least not on bga ec (IT5125VG). Has someone done this before?...Today, 09:10 AM

Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...03-29-2025, 11:02 PM

Greetings,
I was hoping any of you might have the Boardview/Schematic for a Gen2 Lenovo P17 laptop. Specifically for a 20YU model.
Just had one of these fall on my lap that refuses to show any signs of life and i have been unable to find anything (yet).
Any help would be greatly appreciated!Today, 10:43 AM -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...03-16-2025, 07:34 PM -

Hi, I'm working on a MSI laptop, Motherboard number MS-16W11, GF-65 Thin 10SDR-459US. Went to another shop because the screen was flickering, but it was working well on an external monitor. The LCD was ordered and the laptop was returned to the customer and it no longer worked. It was then sent to another tech (by the shop who ordered the LCD) and the EC (ENE KB9028Q) was replaced with a donor from another MSI board with different board number and no programming was done. It looks like work was done on PU6 (TPS51225) as well as one of the GPU mosfets was burnt (I removed all three GPU mosfets)....03-27-2025, 07:35 AM

Original fault was customer spilled milk on unit, no corrosion was found on the board. Took mainboard out of original case and LCD and swapped it into the fully functioning case and LCD.
Shorts show up all over the board when trackpad is connected only. Trackpad is used and fully functioning from another unit of same model. Voltage injection causes trackpad connector to get hot but nothing else, swapped on board connector to rule that out, same issue. Diode reading on IPD_MCU_INT_CONN is higher then reference board @ .935 expected is .803. Shorts show up on PPVBAT_AON_CHGR_REG and...03-31-2025, 09:54 AM -
Hello People, Not been on here for a long time but I have a treadmill to get my teeth into & I'm struggling to find the problem....
So the machine runs sometimes, but then other times I get the error code 3 for Low voltage, so the low voltage could be the motor output voltage from the drive or it could mean something else, all the voltages seem stable enough, like 24V etc...
On startup from a mains power up the relay at the line input socket clicks in & out constantly which its not suppose to do, so my 1st thoughts are with this circuit somewhere.....

Hello everyone,
[U]About me, my goal and the equipment I (don't) have:[/U]
I am brand new to this forum, and I am eager to learn about repairing laptops. I have an engineer background although I haven't done electronics for a while. I have watched several Youtube videos in the last two months, trying to understand how to diagnose a faulty motherboard. I have a USB-C Amp meter and a classic multi meter. No DC Power Supply to inject voltage, no soldering iron to replace components.

Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal.
