Hi, I replaced all the capacitors on the board with new ones, then just replaced the 500uf again, now I have the top half of the screen lit. getting somewhere!!!, I ordered some new transistors to replace the 2sb147. I measured it but being a Ge, it measures funny and still don't know if it is good or not.
I never thought a transistor could go weak but after having replaced the one in the horiz, I had much better results with the HV and raster!?!?. I might have the same issue with the vert output transistor. They are all Ge transistor, perhaps being Ge they can go weak. would it be the case?
