[comp.sys.ibm.pc.hardware] PS/2 video problem

berggren@eecs.cs.pdx.edu (Eric Berggren) (11/28/90)

  Well, I beleive it's a video problem... a friend of mine has a PS/2
model 25 he wants to unload on me for around $120 minus the monitor.
The problem is (simply) when turned on, a display of vertical alternating
green and pink bars (some flashing) appears and any keypress yields a
beep. And that's all it does. The service department wants $450 to fix
it, meaning they couldn't give a damn about it and just wants to replace
the whole motherboard.
  Any ideas what the problem could be and would it be repairable (can an
end user obtain the part without having to go through IBM and several
hundred dollars for a custom package)? Thanx.

You might try running the PS/2 diagnostics and see what it says is
wrong.  To run the diagnostic, perform the following steps:

1. Boot your PS/2 reference disk
2. Pull up the secret diagnostic/low level hard disk format menu
   by pressing control-A
3. Choose the diagnostic option.

Hope this is of some help,
