Question about Panasonic TH-50PX75U Plasma HDTV
We have Dishnetwork. It is nothing to do with them but, we have a Channel Not Available (no signal) message floating around our tv for 2 weeks now. No tv is driving me nuts! Please advise. Thanks, Tina
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

SOURCE: no channel available
Unplug it for 10 secs and plug it back in then wait 10 more seconds and turn it on with the on/off switch. Unplugging makes it reload the firmware, but on/off does not. If that doesn't work try a factory reset. For my Panasonic you do this. Open front door to get at the buttons. Turn TV off. Press and hold the OK button and at the same time press and HOLD the on/off switch for about 3 secs. You should get a self check screen that will last a little while and then the TV will go to the menu screen.

Try checking to see whether your input is set correctly. If you have composite cables connecting your cable box and television, make sure the input is either Comp1 or Comp2. Same thing if you're using HDMI.

on the front of the satellite box, does it have a door that you can open, if so, after opening the door on the inside does it have a red reset button. press the red reset. if no reset unplug for 15 seconds and plug back in. also if its on all channels, and resetting it doesnt work may need to reprogram the satellite. if resetting doesnt work contact satellite provider to reprogram.

What is your signal source, OTA or cable? Did lightning or another type of power surge recently hit? Make sure you have the TV on the desired input.
If OTA check your antenna direction and that you have the Channel Setup (from the menu) set to Antenna. Also check if you have the right antenna to get stations in your area. Antennaweb.org gives the most likely channels and directions. tvfool.com will give more detailed information and more stations. Both sites assume outdoor antennas but the direction information is always good. Look for new construction or big trees that might block the signal. Do you have multiple TVs sharing the same antenna? You might need an amplifier.
If cable, check the Channel setup. Check for someone recently damaging your cable installation (cutting the wires, trying to split the signal to get it for free) Splitting the signal to multiple TVs may also be an issue, get an amplifier of the correct type. Some cable systems may require a bidirectional amplifier.
If you recently had a power surge, see if the TV works with other inputs.
Tuners can be replaced if the TV is worth the labor costs for you.
I hope this helps.
( My household had three tvs and a digital to analog converter that lost their tuners after a nearby lightning strike. We chose to replace the TVs since two were over 15 years old and the third was also out of warranty.)
