Hello! I'm so sad ;( my Vu+ uno died on thunderstorm. I did some tests but no luck, can anyone say his opinion?
What happens when I turn on my Vu+:
It shows strange characters on display for a while and power led change his intensity. After a while all dissapears on lcd and led stays on but at very low intensity.

Tests:
PSU: Ok, all lines at +12v.
Flash BH from USB: nope, it even try to read the pendrive.
Flash VU+ image from rs232: Nope, vu-utility doesn't find the box.
Hypervisor at rs232: no output from the box.

I think that the problem is a corrupt CFE but not sure. Is maybe the Bcm97413 burned or any other component?
My only hope is to try a JTAG reflash but I need to buy cypress interface. Do you think that worth?

Thank you!

check your connection on LNB. if it is short circuit caused by storm, the system will shutdown automatically.

Now I'm running on old dm500 and Lnb is ok. I tried removing the sat module from vu+ and no luck.
Psu is ok too, 12v output
