Dead Vu+Duo repair guide

[franta]

hello guys,
i seams to have a different issue: my receiver seams to go automatically to deep standby or at least this is my impression
i have the receiver since 2010 and 2 years ago i had changed the capacitor. all went ok until 3 month ago when the power source went down , I had change the 2 1500mF capacitors in the middle of the board and all was ok. i had replace in the same shot all 3 capacitors on the motherboard (one was replaced 2 years ago) to be sure...

a few days ago in the morning i find my receiver with red light, but the receiver is answering to he remote and when i pres power is starting , then is telling vu duo and after a few second the red light comes again.
i use one of the latest vix images

I am considering a software issue but i am afraid if i try to install a fresh image will block in the middle of the process and brick my reciver

any advice will be highly appreciated
