The antenna wire goes from the wall to the 3575 then to the TV, the output from the 3575 is through a hdmi wire to the tv. The only time there is a problem is when viewing or recording using the 3575 tuner on FOX or NBC all other channels are fine:PBS,CW,CBS, ABC etc.
Is the tuner on the 3575 just not as good as the TV or is there something I can do?
I should have said gold plated connectors were recommended, not gold tipped.
TV tuners are generally better than DVDR tuners, but the one thing I'm thinking is the 3575's AMPLIFIED coax connection and what diff. it might make if those two channels are DIGITAL, not analog.
Apparently, digital TV signals can be TOO STRONG for some tuners! If they are, they can disappear (go blue-screen), tile, macroblock, etc. One thing you can do if you have a 2-way splitter is to connect the incoming cable to the splitter, then just one output to the 3575 (leave other output open, it's just a test)... this might "attenuate" the signal -3.7dB to see if the signal really is too strong for the AMPLIFIED 3575 input. (Your Panny doesn't have an amp'd input.)
If you have a 4- or 6-way splitter, connect just one leg and that should reduce signal by -7.4dB or so. I have no idea if this will work, but it WILL be interesting cuz I've wondered about this signal strength thing for awhile since I read about it all over the internet, where people are even advising people to insert an "Attenuator" in the line to reduce signal strength (like these, I think?
This might become a bigger problem with the new digital age and people being used to trying to BEFF UP their signals... this might require a reversal of thinking, or at least some awareness of the issue?
EDIT: I just found this on another search of "digital signal too strong" and it's something really easy to try:
"Just to update, I had a email back off Compro and they advised that the signal could actualy be too strong to allow the digital TV receiver to generate a stable picture. I was advised to loosen the RF connector to the digital input (so it wasn't pushed right in).
The signal is actually a lot better now, although I still can't get all freeview channels. So it does appear the signal was too strong for the tuner to cope."
