I have here a working HP laptop power supply with a busted cable. I'd like to replace the cable but the original cable has 3 wires while the replacement cable has only two. Can I leave one not connected?
Cheers

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.

I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before... -
While at university, I connected my HP-Pavilion x360 14-dw0156ng laptop, running Windows 10, to a monitor using a provided USB-C cable. Immediately after this, my laptop's screen turned black and the device stopped working entirely. There are no signs of life such as fan noise or LED indicators, holding the power button does nothing. I've previously used this same monitor model and cable without issues, the cable typically charges the laptop as well.
I've attempted holding the power button for over 30 seconds, removing and reinserting the battery, and trying to power it on with only the...01-16-2024, 11:35 AM -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
