I've got 2 MBRDs. Both have the same problem.

They power up but I get no BIOS screen and no steady green light.
Depending on monitor I use, with Dell monitor I get steady amber and
alternating black screen and "no signal". With IBM monitor I get a
flashing amber and black screen.
But I guess the key is no BIOS screen at all, or steady green light.
Another broken MBRD gets a brief green light off the IBM monitor, but
no BIOS screen, and it soon goes flashing amber.


Clearly both these MBRDs aren't giving a signal. I'm interested in
where the fault lies, even though the MBRD is probably permanently
damage and needs to be replaced.

Would a POST card show me?

Or would it show me nothing since the MBRD isn't POSTing?

I know some POST cards are really expensive, so they must be some
use!! What use are they?

I tested the RAM, and it's ok.(that's no hassle, I wouldn't need a POST
card to test that). I suppose the problem could be the CPU, but I hate
replacing that, what with all the paste and cleaning the paste off.
Would a POST card tell me if the CPU is causing the problem?
And would a POST card tell me which part of the MBRD is broken? ('cos
i'm just interested)
