Hi,
I got a MV1AX MVS stuck on a click of death.
What I already done (or at least what I remember) is:
I checked OE/CS/WE of the work and backup RAM chip.
On work RAM I get some pulse on the OE and WE but CS always stay high.
I suspect CS is not ok. I checked trace, it goes to the SNK1A on the upper left of the board.
Is there anything I can do to narrow the origin of the problem ?
Maybe an unibios can help me to find what's wrong ?
Thanks a lot
I got a MV1AX MVS stuck on a click of death.
What I already done (or at least what I remember) is:
- checking for bad traces - both looking at them and using a multimeter
- removing the battery (had no leak)
- changed work ram
- changed backup ram
- tried with a MV1FZ bios
- checked 5v and 12v
- CPU clock is ok (checked with oscilloscope)
