Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

Hello all, I've been following the forum for a few days now but have not come across anything addressing my issue (a couple of instances of similar problem but no solution).
I have a DSM-G600 H/W ver B1. It has been running for a while on 1.02us quite well. The other day I moved it to a new location in the same room and after plugging it in and pressing the ON button there was nothing but the fan spinning and a little movement from the HDD, that was it.
I messed around with different combination's of ON/OFF / Start Button / Reset Switch but there was no noticeable change. I also tried doing a 30/30/30 reset, nothing. The battery measures about 2.94v.
I opened it up and removed the HDD. My PCB does have a 4-pin jack at J3. Following the instructions Serial Connector page, I went through my parts bin and made a 9-pin male serial cable going to a MAX3232CPE (with the five 0.1uF capacitors) then to the PCB with the appropriate connector. I have checked and rechecked the wiring and pin-outs, everything is fine as far as I can tell.
Measuring the voltages across several pins on the MAX3232 resulted as follows: V2-6=12.93v, V10-14=-7.25v, V10-16=3.34v. It would appear that it's getting the 3.3v from the device on pin 1 as it should. However from the datasheet on the IC it looks as though these voltages correspond to "no connection"...
Next I tried interfacing with it using various methods: getty, minicom, kermit, and on Windoz hyperterminal. They all say connected ( do to the loop-back wiring I assume ) but there is no response when I power up the device. I'm using 9600 8N1 vt100 with no flow-control or hand-shaking.
Is this unit irrecoverably bricked!?
Any help or suggestions will be greatly appreciated! Thanks!
Sounds like bricked. You can still try jtag to look further (http://forum.dsmg600.info/viewtopic.php?id=824), but it might be easier to buy new one.
Sala, thank you very much for the reply! I am afraid that it is bricked also... strange how it happened.
I'm a sucker for lost causes though, so I'm definitely going to do more research on the JTAG approach. If I come up with any new information that might me useful to others I'll post it here.
Mine suddenly did this too, having been off after a power cut... it was totally unresponsive; couldn't ping, couldn't turn off with the button.
it turned out to be the hard drive had failed.
put in a new hard drive and it came back to life.
funnily enough, some time later (today) I took the controller board off the failed hard drive - a western digital WD2500AAJB - saw no sign of problem, refitted it and it worked!
