Hello.
My screen suddenly turned all dim. I can see a bit if i point a flashlight at the screen.
Works with external display. (HDMI and apple tv wireless).
Was told by my local repair shop that it would cost 500$ and 5 weeks to fix it, which did not sound like something i'd like to do............
Anything i can do myself to fix this. I have great experience with repairing iPhone and iPads.
Thank you.

Will most likely be either the screen pcb, screen cable, LCD connector, backlight fuse, backlight IC, backlight IC feedback trace, or a combination (maybe even none of these).
If you have experience microsoldering, and have the required equipment, grab a schematic and board view for your model. If not, send it somewhere.

Well... Yes & No ;-{
You may have blown a fuse link seen here marked in Red:
But there is a reason it blow if that is the case. I would recommend you investigate the root cause before replacing the fuse link. You'll need either a micro soldering iron or heat gun as well as get the correct replacement part.
The other possibility here is the Buck Controller which powers the backlight LEDs has blown. I often see this happen when something was spilled into the keyboard. The chip is on the backside of the logic board seen here marked in Blue:
If you don't have the tools I would recommend you let someone deal with this.
