Duo / DuoLE Tuner problem: signel levels dropped

I have old VuPlus duo. Signal levels of channels kept dropping during the time. I got another Duo box from my friend and it worked fine. For example my Duo showed signal level 61% and my friends Duo showed 80% to same channel. What's wrong with my Duo?

Earlier my Duo worked fine. I think it was about 6 months ago when I first noticed lower signal levels. Levels kept dropping until first HD channels didn't work. Now also SD channels are pixeled. Could there be some component on mobo's signal path to cause this?

Hi, I have a Vu Duo with the same problem,
When there is no signal on a channel I spray the processor with cooling-spray and the signal cums up but only for a while.

I was able to fix this. I replaced C848 with new capacitor (1000uF, 16V). Now HD and all other channels are working fine!
