Re: missing dell 3542 power ic Vin track
yes, it is possible to make such a jumper. it will generate 3.3v/5v only if the circuit is not faulty. Since the trace got broken, the controller IC may be probably faulty.Comment

Re: missing dell 3542 power ic Vin track
there is no way to bypass the 3.3v/5v IC on a laptop mainboard. you have to fix it.Comment

No VIN in charging IC? Are you saying no reading on PU4404 pin No. 20?
If yes then check PU4201 & PU4402 Mosfet. First check shorting with ground and later measure voltage on all those pins and let us know.
Always ask with clear and more information that we can understand.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hello,
I have re-soldered the loose pins on the RAM slot which is a common fault on these models..
It charges and turns on the power LED but is missing several voltages like RAM and CPU do not come up which I believe is due to MAINON & SUSON being missing to turn these supplies on..
What I am un-sure of is what is the ITC chip waiting for to send out these signals, what are the requirements?
I have checked these lines in diode mode and they seam normal -> 600.
I have checked to see if they come on for even a fraction of a second... -
Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. ๐
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Hi guys,
This is my first post! ๐
I have no idea what Iโm doing, but Iโm learning by trial and error.
Iโm currently working on a Dell Optiplex AIO 7490โone of a bunch of AIOs that mysteriously failed to POST just a few days after the warranty expired. The original issue was that the PC worked fine until it was rebooted, after which it got stuck on a black screen (no backlight), with fans spinning at normal speed and a solid white power LED. Forcing it off by holding the power button would just cause it to switch on automatically and get stuck again on...07-04-2025, 12:54 PM -
hey guys, hoping for some pointers to repair an eBay bought "faulty" laptop.
Ill try and give as much info as I can.
Dell Inspiron 17 (7786) Laptop
Service Tag: 5J0NHT2
Bios: 1.9.0
When I received this , it would only flicker on the KB backlight for a second, then off and on.
Then it started getting weirder!
Sometimes when attaching the AC power supply, and pressing various pre-boot diagnostic keyboard keys... it did try to boot, in fact out of a hundred attempts, the laptop did actually boot into the Bios ! but never has...
