problem startup with my EI

[fainardi83]

hello all
i have an E1 with a strange problem
if i turn on my E1, all led is on and the diskdrive don't turn
first i thought that is a problem of power , i checked it and i have both 5v and 12v
i try a strange step is to reverse the data cable , and when i turn on the EI the diskdrive turn, and the led light up
i put the data cable back in the original position try again and don't turn
i need help to investigate for this problem
i have also another shugart sa405 but it s too long and don t fit in the E1
i need to understand the boot sequence, is it a problem of the ROM? perhaps the controler chip for the disk drive ?
do you have any idea ?

regard

ps : i am in france i can explain the problem in french too

Is this recent ?
Is your machine cold ?

If your machine is very cold, heat it with a hair dryer, do not open it, just heat the machine under and top, and try.
