How do I detect a melted via?
I've been trying to diagnose a V4 board that no longer works after attempting an install.. I did the install, turned the system on and black screened.. then checked and double-checked everything.. black screen.. So then I removed the chip completely by desoldering all points on the board. However, the PS2 still will not boot up and stays at the black screen..
so I checked for pin bridges, stray solder bits, all fuses which I could find, and still couldn't find the problem. So not knowing exactly how to proceed, I thought I should check that the VIAs are still okay..
What is the symptom of a melted VIA? Will I just have no continuity on the VIA point? Should I check for continuity between the dvd controller points and the corresponding points on the bottom of the board?
