I am after a wiring diagram of a SOLA/Powerware INT-0025 cable, used for a UPS. If anyone has such a cable, I would appreciate a wiring diagram of it.

hello everyone, I'm looking for the wiring diagram of this led monitor.
the model is DHI-LM19-L200, but I think that any other diagram of a DAHUA monitor could be equivalent.
I really hope that among you someone can help me to repair this monitor, the screen is black, it doesn't seem like a backlight problem.
I see the presence of 12 volts, 5 volts, but without a diagram the repair is very difficult.

I have a Power Cool UPS to fix seems to have festered its mains plug blowing a 13A fuse now will not fire up correctly, output rises to over 250v before shutting down.
I think the key fault maybe its IC HR6P72P4DL a 28 pin DIL chip which I think is like a PIC chip with a program, I suspect its a variety of TI chip re branded like many others.
If anybody can help with a circuit it will help try to figure things out.
I have changed the two 22uf 100v which seem to be a snubber to its power Mosfets 3 x 24v relays with 1 x 12v relay plus a LM324 underside...08-21-2022, 12:16 PM -
Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:
The schematic...
