New tool I received from AliExpress. It's a mini power supply and it can also make it easy to repair shorted motherboard. Has any one heard of this?

Re: New electronics repair tool. Strong Power supply HR-1520.
There are a couple of threads of them here yes, I can't off the top of my head remember where they where discussed though."The one who says it cannot be done should never interrupt the one who is doing it." -
Re: New electronics repair tool. Strong Power supply HR-1520.
Hi - and I find that interesting - if you have a link to this on Ali - let me know - I do bench work and usually have an ATX power supply laying around but this looks like a good idea.
Thanks for sharing...

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... -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
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 Everybody,
Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)
Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).
The outputs marked 12v and 20v are all measuring only 1v.
The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.
The capacitors physically look clean (no bludgesor leaks) and... -
I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem...
