Sony PVM-8041Q 8 Inch color monitor - Only green!

So I ordered this pvm quite a few months ago maybe a year by now, anyway it’s a pvm and after buying the proper adapter plugs for the proper wires, the signal only comes up as green, I’d state more troubleshooting issues if people are wondering but I eventually came to the conclusion that it was an internal issue, stupidly enough, my intelligent being self decided to open up the thing thinking I ‘might be able to see what’s up’, (was partially aware of how dangerous power supplies are and other components on the board so I basically just looked around). everything looked fine, there was no wear and tear or erosion that was alarming but I was basically told i had to resolder the points of solder which I was not about to do. Anyone feel free to leave a message if they know anyone who could potentially fix it at a reasonable price mind you I’m broke so putting hundreds of dollars isn’t ideal if that’s the only option. Thanks.
