Hope this helps someone……
When your EPG stops working and will not download.
ERROR....... Timeout for tuner lock
This how to FIX!!! …. Astra 28e…..
Epg is only found on this freq -- DVB-S, QPSK, 11778 V 27500 2/3
Check to see are you receiving this frequency as it carries all EPG info for Astra 28.
If not then check all connections to STB.
eg Cables, F connecters, LNB Connection until you have a signal!!
When your signal is there(back) - scan frequency and restart GUI.
Now you EPG should work again...
