I have no red light, nothing at all when I turn the switch on at the back. Any ideas?
check power fuse

Hi, my vu+ duo won't start only showing redlight at the upper right corner . Took it to the service center they told my I have to replace the motherboard which is very expensive . So I decided to buy a new vu + solo 2 instead.
After reading this forum I want to give it a try and fix my vu duo , it has all the symptoms listed above so I think it might be a capacitor thing but I have no experience with soldering .
How do I get sure that capacitor c807 is the faulty one ? It doesn't look like leaking or damaged?
It may not display any physical signs but it's still worth a try to replace it as the capacitor is only a few pence and 20 minutes to replace at most. after all the box in it's current state is fir for nothing but the bin so you may as well give it a go.

SIMPLES.
Easy way to check if it's capacitors. Remove the top, get your hair dryer and heat it up. Then see if it comes on.
Never heard of this to check an electrolytic cap....! I'm an electronic engineer and can tell you this will not check anything, apart from tell you if the solder joint is suspect which i doubt.
Only way to check cap is with a capacitance meter which places a small load into cap to check its function

You are right, mate !!
Here is my story on the DUO:
- redlight issue, did not boot anymore
- replaced C807 ( the famous one ) + the regulator U801
- boots again, but have severe problems on HD-channels, not locking
- after a while HD working, except the critical ones ( 8PSK here in Netherlands )
- I discovered that if the box is heated, everything works....
- removing cover, heated extra with hair-dryer and the SNR goes from 68 to 72%
- used freeze spray to identify another faulty capacitor : C848 !!
- will let you know the result after swapping this capcitor
great results after replacing C848: SNR now increased to all time high values ( for me ) and HD-channels very stable !!

Should I replace the cap????
Over the last few months im having freezing problems with my vuduo (not clone) i have it about 3 years, never gave any trouble until a few months back when i updated the image after about 6months, this might be just a coincidence but ever since its been freezing i.e spinning vix, when changing channels, moving through the menu etc and recently rebooting itself every hour or so its almost unusable at the moment. I have reflashed the box several times and set it up again from scratch but get the spinning vix within minutes. I tried enabling a swap file, have only essential plugins installed and have cacheflush installed, but still it freezes every minute, it also reboots every now and then, and interrupts recordings, the wife is on my case bigtime about it now, need to sort something out soon. I also flashed a blackhole image and old kernel version of vix but neither helped the issue. any advice wold be great?
