I have this problem with my stb. I own a Strong SRT 4620XII.
When I start my stb it lights up but it won't load any channels.
Just a black screen on TV and four dashes on the stb's little display.
I did not what to do, so I restated the stb several times using the back switch.
By luck the stb started. I made advantage of this and downloaded the latest software from Strong's company site and updated the stb using my usb memory stick. The update process went successfully.
I left the the stb working for a couple of hours then I restarted it to see if the problem still exists.
Unfortunately the problem still exists, and the stb wont load the channels but it lights up though.
So any suggestions???!!!
Thanks in advance for trying to help me.
