I just picked up a Sun Netra T1 200.

It seems to have some hardware problem. When you plug it in the repair
light flashes 3 times and then nothing happens. Pressing the power
button does not start the system.

I can access LOMlite and here is what it outputs

If I type poweron nothing happens. Any ideas?

Thanks!
