MBP 2012 (13") - Bootloop when magsafe connected. Shuts of black.
MacBook Pro 13" Unibody Mid 2012, starts up and shuts immediate off, when connected to the Magsafe. Then it stays in a Bootloop/Black screen shutdown (and infinite repeat).
More information can be seen via https://youtu.be/zues-vTE4C4.
Things I’ve tried.
- SMC reset. (won’t even get the possibility to try)
- PRAM reset (won’t even get the possibility to try)
- Take battery out, connected with Magsafe
- Verbose/Single User Mode (won’t even get the possibility to try)
Unfortunately there hasn’t been a solution. Does anyone know which problem this could be?

Unfortunately I haven’t found corrosion on the Logicboard.
Any other possibilities that can work?

When RAM not inserted, it will beep:
One tone, repeating every five seconds: No RAM is installed. If you recently replaced or upgraded your computer's RAM, check to see if it was installed properly. https://support.apple.com/en-us/HT202768
Unfortunately when RAM back inserted, it will get the same Bootloop/Black screen.
Update (06/04/2019)
Checked RAM-memory, and the two RAM-slots. Still no solution, to Boot the MacBook Pro.
- RAM 1 2 (both memory sticks)
- RAM 2 1 (changed memorysticks order)
- RAM 1 (One single RAM in slot 1*)
- RAM 2 (One single RAM in slot 2*)
*both memorystick tested.
