I have an xecuter 2.6 and it has worked without problems for a long time. Recently, it only works half the time or less. When I power it up it turns off twice and then stays on with a flashing light.
I've checked each solder connection for continuity and cannot find a problem.
Also all the leds light up as expected.

I've also checked the switch cable and did not find a problem there either.
One bios bank is running xecuter2, latest bios. The other bank is the original cromwell. Starting with either doesnt matter - same results.

Any suggestions??

Which bios do you have in each bank? For the 2.6, I think that the bios works much better when flashed to bank 2. You can flash bank 1 with the cromwell.
