I have the Veon 101 connected to a 42 inch Samsung (Plasma )via hdmi and don't suffer this issue , have you tried connecting using component or composite..
What is the Signal Strength / Quality like ?
Mine are SS 72% SQ 98% as a baseline.
This may fix your problem.
Fuzzy or Blurry picture
The steps to correct this are as follows
Switch the receiver off either using the power switch on the rear of the unit or at the wall
Switch the receiver back on
As soon as the receiver displays "load" press "up" "down" "up" in quick succession on the remote
The receiver will then perform an EPROM erase and restart
After the EPROM erase process has completed you will be prompted to select your region and press ok.
Once the scan process has completed you should have access to all channels again.
