HD8000 not turning on

[ssj92]

I recently got a hd8000 from eBay. The green power light keeps flashing and the fan keeps trying to spin but stops.

This process keeps going on forever, no video, no front blue led text.

I looked at the power supply visually and don't see anything unusual.

Is this thing done for?

I see possibly 2 fat caps but the pic angle isn't the best.If it has an 8psk installed, try removing it as well as all external cables & try again.Short of that,use a dvom to measure the various outputs on the power supply.The values are marked on the board.

Looking at them far left plugs they look like it may have gotten wet or hot by the looks of the board.. around the plugs..

c86 looks fat to me

c86 looks fat to me

agreed...a little too tall.lol.

this is just me but i would have it rebuilt by the guy on ebay. u said u bought it off the fleabay so i would have it rebuild personally just because you don’t know anything about the power board. i agree the caps look fat lmfao

If you're refering to Danmarco, I don't see him on ebay anymore.

Danmarco has retired from the FTA hobby/fixing stuff since I last talked to him which was a while ago

If your going to be poking around on that power supply board with it plugged in be VERY VERY careful as that's a switching power supply, it has some very high AC voltages on it, you could wind up crumpled up against the wall wondering how you got there.

And yes several caps do have a distinctive bulge to the tops, also look at the bottoms. If you don't think you have the skills or the equipment to replace them then find someone that does.

I agree 100 percent.Not worth getting hurt or further damaging your situation.
As much as it sounds like power supply, I would still verify.

I believe I got his LAST SV8000HD, totally rebuilt with Built-in LAN-port as well as some
of his Red HD boards he did, still have 2-HD Boards kicking around, if someone is Looking for one.

o he is still there in the shadows keep looking

[ssj92]

I can't find my multimeter, need to keep looking. I could measure the voltage at 12v, 3.3v and 5v. Also can read capacitance.

I was just wondering if this sounds like a power supply issue.

To rebuild would it be better to replace all caps on 12v, 3.3v and 5v? Or is it normally just 5v and 3.3v that go bad?

If all I need to do is remove a bunch of capacitors and solder new ones, I can do that. I message the eBay seller to see what they want to do first but otherwise it seems better to just repair this power supply.
