One evening I suddenly had no TV -- Slingbox was out , flashing lights for BOTH internet and power.
I checked all connections, reset the slingbox, even did a complete reset of modem and router --
but I had no signal passing to the tv.
I disconnected slingbox and everything worked normally so I knew it wasn't my cable feed.
My internet on computer use was perfect ...
Even though I tried another supply with the same ratings, nothing fixed the problem until I get the OFFICIAL Slingbox Solo power supply in the mail and tried that fix --- PHEEEW -- it was either that or the circuits were friend -- caught a break for once!
