I recently purchase a vu+ zero box and got it setup working perfectly for my FTA sat channels and my IPTV subscription.
over the past week I have gradually been linking the IPTV channels with their EPG source code with e-channelizer and everything was working great up until today.

I had a couple of crashes, and now all of the IPTV channels say :
No data on transponder (time out reading pat)
I have tried a factory reset and loading all channels again but I am still having the same problem.

PS : all of my FTA sat channels are working fine, I have a multi LNB fixed satellite.

please can someone help me.
