Thanks for the Sticky had the red light of death at the weekend changed the capacitor and it came back to life, nice fix for under one Euro and 10 minutes work.
It didn't power on when my sisters Duo got the red light. Her issue wasn't the C807 capacitor though, it was the U801 regulator that was gone so perhaps that's why the fan did not spin up..Originally Posted by Hunty

When the box is being used while the C807 is dying, the next in line to be damaged is the regulator.
So best practise is: when the very first sign of C807 issues show, cut the power to the box and don't use it until the cap has been replaced.

My box has been crashing a lot recently, several reflashes and still not working. Had lots of horizontal lines on the picture today and the remote control was unresponsive. Power cycled the box and it worked ok for 30mins then the picture would freeze but the sound carried on as normal, after 5 minutes it turned itself off and back on again. Removed the duo from my AV cabinet, Opened up the duo and plugged it into the wall only to get a red light with no display.
Decided to strip the box down and cut the capacitor off the board. it measures out at 56uf on my digital multimeter.
Also noticed this mark on top of U801 - looks like the casing of the chip has burnt?
Yes, looks fried alright...
Reckon you need C807 and U801 replaced and maybe more... My U801 was gone but it didn't look anything near as bad as that!!

Hi Mate,
You quote 'If you hear the drive spooling up on power up, and the box is dead, it's a reasonable indication that the power supply itself may be ok!'...
What if the drive does not spool and I still get the red light. Does that mean the PSU is dead as well, or can I get away with replacing just the Capacitor C807 and perhaps the regulator U801?
My drive did not seem to spool up and i just replaced the C807 capacitor and it came back to life.
I would try just the capacitor first as it is dead easy.
New U801 from ebay for 12 quid sorted it.
Had the 3 220uf caps replaced and they had to replace the smaller ones either side due to signs of failing. 105degree good quality japenese caps installed to replace the chinese ones.
Hi guys
just wanted to say thank you for this wonderful post. It worked saving me a fortune.
Thank you again
Is it possible to remove the green board with c807? I have unscrewed everything but the card reader is basically stuck to it so can't pull the board free. I wanted to remove the board completely from the box to do a proper solder.

yes it is, I removed the full board from mine.
You have to clip off the front facia and I also had to remove the HDD to allow me to manouver the board out.
Part of the card reader stayed on the board when I took it to the repair shop
Aye, front facia. That is what I was thinking. Have it off now. Will give the soldering a go tomorrow. Hopefully it works and saves me a few quid. Repair shop wanted €90 for this!

Looks like I am another member of the red dot club...

Not the best picture... but looks like U801 has gone?
Is there anyone on here I can send the board to who can repair & send back to me?
I would much prefer this to DIY or rip off repair shop.
