Something like this might be interesting for testing. But in the end it may be better to just open the monitor and solder another cable.

Eh.. never mind I think it may be toast. I just plugged it in and it's producing white bars that slowly inch up the screen. 😒

Yeah, I tried re wiring the vga cable before and it was pure shit. Maybe take off the back and see if you can plugn in a new vga cable?

It looks as though I can plug in a new cable. But I'm not sure the monitor isn't completely shot, when I turn it on white bars slowly inch up the screen like some sort of idle pattern. I've never seen a monitor do this before but if it is shot it's too bad as the CRT looks pretty crisp if those white bars are anything to go by.

Do a visual inspection of the electrolytic capacitors, see if you spot any with a swollen top/bottom, deformed plastic sleeving or fluid leakage.

Visually all the caps look A ok. Everything looks fine on the surface, problem is I don't know what this particular model of monitor is supposed to do when it's inactive but on. I'm actually kind of inclined to think it may actually work if I manage to get my hands on another cable that I can plug into the board.

Hey I made a quick video to show exactly what the monitor is doing. What do you guys think? Is it shot or is this a "no signal" pattern?

Those are very perfect looking bars. I was expecting something else.
On the other hand, I don't think I have ever seen a monitor do that

Yeah it's weird. It doesn't look like a malfunction. 😒

That looks very digital and deterministic, like coming from an internal pattern generator. I used to have a Packard Bell CRT monitor from the early 2000s which used to display a crosshatch pattern when it received no video input, so I'd say it's not unheard of for something like that to exist.

Yeah, I'm going to have to try and locate another monitor so I can steal it's VGA cable.

Do you know if the scraper how trowned on the other electronic waste? Maybe its have some damage inside the tube..

I looked inside and the tube looks good to me. In addition the caps look good also. 😒

That doesn't sound consistent with a tube problem.

I just wired up my first attempt at a VGA cable and I think I almost got it right, the computer monitor seemed reconise that something was being recieved but I missed a few wires that I thought were sheathing so I have to try again. I think this monitor may live yet. 😁

When I say it recognized it was recieving something it didn't go into the test pattern when the VGA was plugged into a computer that was running.

Nope same thing... Uh I give up. I guess it's going back to the recycling center. What a shame though I really do want a Packard Bell monitor for this computer 🙁

Hmm someone that has the exact same monitor just told me it is indeed a test pattern. Well maybe I just suck at making VGA cables then, I'll have to go over to the recycling center and see if I can't find another monitor that I don't really care for to steal the VGA cable and plugs from.

Would it have a setup menu accessed with the front panel buttons?

And yes, there is a lot of stuff in a VGA cable
