The
Vietnamese channel (called VPTV) on AMC4 is a piece of cake to snag - at least compared to VTV4 on
IA5.
Make sure your receiver is set to the proper transponder coordinates for VPTV: 12020 MHz, VER & SR=30,000.
Also check that your receiver setup matches your LNB type - ie: standard or universal. Make that "LNB POWER" is turned "ON" in the receiver. Make sure your mast is plumb and all that jazz - see general
installation hints on
Sadoun's website.
