I too have joined the ranks of having a non working HD1000. Has anybody seen this problem?
The unit does not power up, no front panel lights and no ethernet port lights either. The power supply LED is green and not blinking. Upon checking the voltages on the motherboard, TP 58-2.5v, TP 45-1.8v, TP 29-1.5v Then I checked the 5v test point on the motherboard next to the power supply connector, it reads 4v (ah!) and 3.3v reads 2.7v (another ah!). Nothing feels hot, there are no burn marks. I took off the metal shield on the power supply and all the caps "look normal". Any ideas? I'm thinking the switching FET and C5 or the 7805.

Thanks, Henry

Sounds like a power supply issue...
You can shotgun parts and if you don't fix it through some serendipity, then you can send it to Pyramid-Audio.
See if you find some help/ideas in this thread too ( http://forums.rokulabs.com/viewtopic.ph ... &start=276 )

Check your PM, I sent you some more ideas.

Regards, Matt

After further snooping I find that the input voltage to the 7805 is 5.6v, from what I remember I believe it should be atleast 7.5v for proper regulation. I wish I had a schematic.

If you find a schematic, let me know, we/I had to reverse engineer everthing. A schematic would make life a whole lto easier. Check your PM and we can figure out some TP's to probe.

Just wanted to share my extremely positive experience with Matt and the folks at Pyramid Audio. Got my Roku power supply fixed with quick turn around! What a life saver!!!

Let me try it first....

Any luck with this one? One of mine just died with the same symptoms. No power LED, no ethernet LED, but under the cover the LED on the power supply is lit green.

This Roku has been worked over by Pyramid already (does that work come with a guarantee?)

This really smells of U12...

There are times that even when the heat sink is added to a prevoiusly in use (read came with the unit from day one) U12 that it (U12) still croaks. I assume it may have had one foot in the grave and then just gave up the fight? Call Pyramid-Audio and see what they say. There is a warrany, I just don't know what it is.
Hope this helps, Matt

The heatsink above the ATI chip is warm, but above U12 it's stone cold.
It's going to be on its way back to Texas again next week. Thanks to Chris @ Pyramid for agreeing to cover the rework under the previous repair ticket.

A ticket do not have to worry about maintenance, the results showed that, but it would be better not

Can you point me to the thread (or just re-append) the information on how to get in touch with Chris @ Pyramid? I'd like to send my (previously Roku-repaired) Roku to Pyramid.
