I have also the red light problem on my VU+Duo. It startet some days ago, when shifting to certain channels the VU+ restarted. Today it restarted while in a channel after about 5 minutes. And then i stoppes working and it had the red light on. Off, wait, On: Nothing happened. Wait untill cooled Down: Nothing. In january 2014 I updated to OpenPli 4.0 without any problem. I have had some sat.receivers before (Nokia, Peace, Techview). After around 4 years most capasitors have to be changed. Average 4 hours each day and 4 years is about the Lifetime of most capasitors. After putting in the new capasitors the receiver was as new.
I bought this VU+Duo summer 2012, maybe the 3.5" harddisk can cause faster aging of the capasitors? The spinning takes a lot of electricity and the powersupply is not that big. I will try a SSD or a fast 2.5" in stead.
This evening I tried to reload the newest OpenPli, but no response from the VU+. On this forum I found a post about C807. Now I like to try this solution changing this capasitor. In Norway elfa distrelec can be used to order this 16V 220µf. I hope it helps. Thanks to the people who found this solution!
