Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.
So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.
My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...06-24-2024, 01:24 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... -
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.

But 3v LDO was not generated.Then i checked the enable signal of the ic.It is perfect according to datasheet.Then i checked the impedence.It is perfect(444).So i replaced the 3v ic.Then worked.
Again next day, same issue.then i decided to disconnect the ldo line by cutting the path.After that LDO generated well.Then again connecting... -
Hi all,
I've had trouble with the power on this device since I got it. It always shut down with no warning and would often fail to power up. Dell's advice has been to disconnect the power and battery, wait, then reconnect and boot. Letting the battery run down completely also helped. I had them come out at one point and they said they replaced the board. This helped for a while but then it just stopped powering on. At this point it's well out of warranty. I missed the chance to get them to come out again because life. Current situation is it shows zero signs of life with both barrel...
