I had issues with my a1989 mbp (no internal display signal). I didn't bother to go to apple since it's out of warranty and I wanted to save some money. I sent it to Rossmann Repair Group. Today they called me that 1. need to repair the board which will costs 420$ 2. need to replace the screen in which they don't have in stock yet. The screen costs about 400$ on eBay which makes the whole repair more than 800$. My plan is to buy a used one (around 1000$) and sell the broken one (hoping to get at least 600 back). The MacBook Pro functions normally except the internal display doesn't work (you can use external display), but not only the display, the board has a burnt mark, however it doesn't affect any of the other functions (the burnt capacitor is probably why it killed the display). I have two options: sell it for parts, or sell as a whole; my point is if it functions just like normal except the display, selling for whole might make more money. Here's the spec: MacBook Pro 13'' 2018, 2.3g core i5 (i5 8259u), 16gb ram, 256gb storage, no internal display signal, external display only works after booting into the system (doesn't have signals while booting, no apple logo, probably has something to do with the burnt mark on the board). edit: spellings and added information.
