SA 8300HD - Signal problems

I subscribe to Oceanic (Hawaii) Time Warner and have the 8300HD box.
One of the HD channels (local station) does not show any picture and
another (another local station) only displays in SD. I am able to
receive all other HD channels (approx. 6 others). Not sure what the
problem is because the channel that has no signal used to work and the
one with the SD used to be received in HD. I reset the box, but can't
figure out what's wrong. Any suggestions? Thanks.

You might try going through the initialization procedure to
enable 1080i or 720p output to the TV. Maybe that setting
got screwed up somehow.

I re-initialized the box for 1080i and 720p again and also tried the
different settings on SET: PICTURE FORMAT, including AutoDVI/HDMI.
Still no luck.

Call the stations. They may not be on all the time, or are down for changes.
Or, maybe better, call the cable company. You could also check the TW web
site to see if they changed channels.

Sounds like TW is changing some things on their end, can you ask them?

There is a way to get into diagnostics mode which will show the signal
strength of the channel ... if the signal is too low the channel will
go blank, macroblock, etc:

Thanks Mark. I did check with TW and they said that I should be
receiving the signal. I will try the diagnostic to check the signal.
If by chance the signal is weak, do you know what might be the cause
and remedy? I hadn't made any changes to my system prior to this drop
out. Thanks again.

One way to diagnose a problem like this is to connect your cable
box/tv directly to the cable connection at the side of the house, ie
bypass all cabling in the house. I did this once, and found the
problem remained, so TW came out and ran a test cable from their
distribution pedestal to my house - problem remained so they had to do
something further upstream.

I had a cable problem here that got so bad that Comcast was unable to ping
my cable modem. Turned out that the cable coming in off the pole was so
corroded at the grounding block that the center conductor was black. Cut off
about 6 inches, crimped on a new F connector (also replaced the grounding
block) and everything worked fine.

Will be switching the cable box tomorrow. I'll let you know if this
solves the problem.
