SE/30 video problem

[Ildefonso]

Hi all you.

This is the video I get from my recently adquired SE/30. No chimes at the boot, but the desktop and the moving mouse pointer can be barely seen, meaning that that the logic board works, but there is an evident video issue.

Cleaning the logic board and changing all the capacitors (except the two axials) has changed nothing.

Any idea how to solve the issue?

A multitude of broken traces. 

Likely A0, A1, and a number of other ones are broken between the video muxes, ASC, GLU, and a few broken between SCC and SCSI and SWIM. 

good luck!

mine did that when a cap did not make a clean connection by the motherboard plug when I replaced them.

That sounds not very promising, meaning I will need a lot of work and luck to make it work againHow can I identify this traces in the board and in the schematics?
