I just finished building a house and had an 8 bay UHF antenna installed in the attic. The coax runs down to the basement into a box where it is amplified and then split to two TVs on the main floor. One in the master bedroom and one in the living room. Both TVs are Panasonic. The living room TV is a Z series 50" plasma that is about 5-7 years old. The other is a middle of the road 42" plasma that is about 2-3 years old. I used them both with OTA in the past with no issues. Both TVs have the coax outlet on close to the floor with the TV mounted up high on the wall with a conduit in the wall to accommodate the cables. The coax run to the living room is at least 20-30 feet shorter than the run to the bedroom.
My current issue is that the bedroom TV will clearly receive all local channels at 85% signal or above. The living room TV will only receive two of the five local channels. One of the three I am missing comes in at about 93% signal power on the bedroom TV.
Things I have tried:
- Switching the coax on the splitter and swapping out the splitter
- There are two coax runs from the box in the basement to each TV (one for OTA and another for Satellite) so I switched those for the living room as well, thinking that one cable may be bad.
- Switching cables from the outlet to the TV in the living room
None of these solutions have mad any difference at all. Could the tuner in my TV be going out? The only other option I can think of is to take the bedroom TV off the wall and move it so I can hook up the living room coax to see if that is the issue. Is there an easier way to test signal strength for individual channels coming from a coax? Any other options that might work?
Thanks for your help.
If that fails, then maybe you have to bite bullet and test that bedroom TV (tuner) in the living room. Or.... take the living room TV to the bedroom.
I tried to convince the wife to let me buy the new Panisonic TC-P55ST60 before we moved in but she didn't go for it. I'll have to try again.
One last suggestion. I'd suggest that you remove the TV from wall power for a few minutes. Disconnect the antenna from the TV.
Plug in power, turn on TV. Double check that the input is set to AIR/Antenna (not cable) and run a channel search/scan with the antenna cable disconnected.
Once that completes, reattach the antenna cable and re-run the channel search/scan. (And hope for the best).
It's possible that some kind of interference is causing your problem. At my house, LED light bulbs or a laptop computer in the vicinity will cause me to lose one channel. It could be that only your older TV is affected because the tuners in older TVs may not be as good as newer models.
Your signals are weak to extremely weak. Think large antennas up very high. The stations are actually not as far away as their strength would indicate. Perhaps a large hill or mountain is blocking them.
Also, how far away is the amp from the antenna? Ideally the amp should be as close to the antenna as possible.
Finally, what kind of amp do you have? A pre-amp? Distribution amp?
I have a Channel Master Model 0747 Antenna Amplifier. The antenna has about 50-60 feet of coax between it and the amp. Then there is coax out (1') to a splitter which then hooks up to the living room and bedroom coax. As I said previously, I brought the master TV into the living room and hooked it to that coax and received all channels. When I hooked it back to the living room TV I lost all but two.
That's the indoor power supply portion. The amp is outside and you'll have to read the model number off of it. Should be something like CM-777x.
I don't know why pulling the power for a few minutes and then running the auto program without the coax plugged in and then again with it plugged back in wouldn't produce the same results. I have a sneaking suspicion my 1 year old pressed a lethal combination of buttons on the remote. It is his absolute favorite thing in the house.
Thanks everyone for all of your help.
I keep a box in my basement with used remotes, each of my grandkids got to play with them when they were toddlers. They knew that Pop-pop's remote was a no-no.
