Roland XJ740 WEIRD test print.. pls help.

[reclab]

Hi everybody.

I wanted to ask you if anyone experienced this and how do we go about fixing this problem.
please note that i'm not an expert of this but i'l try my best to follow any instructions you throw
at me..so please I really need help..

by the way, here's the testrpint:

 

[FrankW]

An electronical peoblem. perhaps a weak head cable.

 

[meritan]

it's an electrical problem, you need a tech to resolve this problem, don't do anything by yourself

 

[SIGNTIME]

most likely a data cable...

 

[Jack Knight1979]

I can confirm that this is indeed a data cable issue. I've seen it three times on my machine over the years. You'll probably need a tech on this one. It looks as though you have a blown C channel which could do as far back as the head board.

What happened to the machine before this started?
