[QUOTE=logo29a] It only seems to be the first three HD channels (101.1-101.3). The channels frequently block up and sometimes even disapeer for a second. The other 3 or 4 channels broadcasting in HD do not have this problem. This is a new construction home. Should I be worried about this or will having a STB make a difference in reception? Is there anything I should know before contacting the cable company?[/quote]
Don't know what channels 101.1-101.3 are. Sometimes there is a broadcast or network problem that causes some to block or tile and others to appear fine.
[QUOTE=logo29]]On a side note, the cable was just recently run from the box to the house and I'm fairly confident in the quality of the cabling within the home. Thanks![/quote]
Check to see what cabling is IN the house, quality of cable AND connections.
Should have at least RG6 cable. The connections/connectors can be replaced easily by you unless you have a cable co agreement where they replace.
A bad connector can cause your problem or too many splitters which reduce DB.
If the cable/connectors are OK and no splits then it maybe the cable co signal.
A weak OR STRONG signal can cause problems.
If you have NO splitters between the HDTV and the main house connection you can try adding one more splitter at the TV. IF the signal is too strong the additional splitter will knock the DB down.
Otherwise goto Rat Shack and by a BiDrectional signal amp that can be adjusted
UP or DOWN with an adjustment screw. More expensive than extra splitter.
This is what I had to do for a weak signal.http://www.radioshack.com/product/in...entPage=search
Can ALSO put a small HD antenna in the attic and get LOCAL HD free without cable breakup hassle.
Wish I lived close enough to do that.
If the wind blows or humidity is up around here the reception gets very poor even with the amp.
