I am organising my posts. Please tell me exactly what the heck this=20
"Prima" is? TV? PTV? Projector?
No where can I find a description. The subject line is useless as far as =
what the unit is. We need to say: "Prima 20 inch TV modelxxx" or such.=20
Many of us are not familiar with brands not sold in our area. And saying =
this "unit" did this or that ...
Thanks,
Phil Bader
