X1000 problem

Any good ideas to why an x1000 won't start?
Pushing the power starts the system for one sec, and then nothing...

PSU issue?

I had the same problem before, sometimes my X1000 refused to boot, so I unplugged the PSU from the motherboard, plugged it again, and everything is fine since then.

Needs to go back for repairs. Some chips are burnt. :/

Seems like something regarding the psu went wrong.

I can't see anything, the picture is far too small.

If chips are burnt that look like in this photo


Take a look at the top right.
Left of the white square cpu power plug are 12 black square chips with two legs.

If those are fried then the voltage coming to the board was too high.

I saw that on an XE once, someone was playing with the cpu voltage and blew the board

Had a similar problem, somewhere in the middle of the linked thread:

I had to sent it to AmigaKit to get it done. Running smoth since then...

@Antique
A bigger picture would be nice. (Yours was just 'thumbnail' resolution.)

@ChrisH

Have added a link instead with a bigger picture.

Well the picture is clear, some components are blown, yes.

time to ship it back to amigakit for repair

and get a new psu ! ^^)

Did you have a surge protected power socket?

Sometimes they offer some insurance if your appliances are damaged like this.

@ddni

There is never lightning strikes during the winter period in Norway, impossible to say what caused this. This is a beta tester motherboard, there where some revisions before the final nemo motherboard.

@liveforit :

X1000 betatesters boards and consumers boards are the same v2.1 revision.

Looks like a power supply bypass cap failed, sometimes they just open up, other times they short out when they go. I wouldn't blame it on the PSU, just appeares to be a failed cap, makes a mess, but easy to fix & shouldn't have caused any other dammage if it is.

Polarized caps like those will blow on powerup if their weak, they fail more then any other component because they take a current surge, Always a good idea to power up a system once a month to prevent bypass caps from discharging.

Reminds me to turn on my oscilloscope again, its blown 2 bypass caps letting it sit in storage too long.

@LiveForIt

They protect against power spikes caused by a huge range of things, not just lightning. In fact I suspect a lightning strike would destroy the protector and anything plugged into it.
They are most useful for smoothing out the power when high drain devices like heaters and showers are turned on or off. I use them religiously with any sensitive or valued appliances.
