I got a defective Virtua Boy from a customer with the Glitchy Display Error.
After a quick research i found: http://www.projectvb.com/displayfix.html
I used the Solder Method for repairing:
For removing the cable I was using a Fiber Pencil like this
and after this It was possible to resolder the pins @ 230-250Grad Celsius.
And it works, great again like the first day
One little tipp: check the cable connector if its connected right at the other side.
If its inserted to much, you will get no picture from this site…
