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.

Hi guys, appreciate any advice on a my Laptop I spilt some coke on,
I damaged the audio circuit, UR630 AND UR600 ic SN012776B0YBH were hit, I removed them and replaced from a donor board and made the area very tidy no shorts etc, started it up no Sound, went back to looking at the board and noticed UR660 which wasnt affect by liquid was very hot so changed that also, Now machine wont start and I only have 12.3v on pbus, I have 20v 0.3a on all usb C connectors but no light at all on magsafe, I did notice the battery has 10v when not connected to a charger through pbus fuse, which ...Today, 06:32 PM -
I bought a case of them the battery cells are made in China the charge curve looks decent for 1 amp charging rate there is also a BMS protection board which here is the website link to them

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
