Vu+ Solo2 box not showing sky channels

Recently during the thunder and lightning storm our phone line was hit, actually had a big spark from the phone outlet on the wall. The modem power supply was fried, I got a replacement modem but my Vu+ Solo2 still will not pick up all the channels, it will show the free to air English and Irish channels but not the sky movies or sports etc there is no picture or sound but the box downloads the 7 day guide and shows what programme is on a sky channel and the description. The Vu+ solo box is not directly connected to the modem, I am using home plugs to send a wireless signal to the Vu+ Solo box. I have even changed the home plugs so it wasn't those.

So to recap:
Modem changed and working
Home plugs changed and working
Free to air channels received so dish seems ok
Sky channels downloading guide and show description

No picture or sound for sky channels

Any help will be great
