There may be a issue with the tuner on the set but there is a way around that.
With a cable box with audio/video out jacks connect to the same kind on the rear of the set---go to that input on the set and should see picture and sound---leave set on that input and change/select channels with the box.
Not familiar with your model, but the problem sounds generic. I am guessing your set is hooked to a cable tv box, and that is where you need to change channels. I also guess that when you changed channels on your TV you probably moved from channel 3 to either channel 2 or 4 and the cable tv box is not sending to those channels so you lose picture and sound. Now, more guessing, you try to put the channel back to 3 on your TV, but still nothing happens. OK, if close so far, there are a couple of things to try. First, be really sure you are actually going back to the same channel you started with. Assuming you don't actually have the signal coming in on an auxiliary line-in and that you had it coming in on a channel, you may need to reset the presets on the television so that it recognizes the one important channel the cable tv box is sending out -- just follow your television menu to select or set channels. There is one more possible easy problem ... I have seen this one happen, after getting the channel correct and reset, if it still doesn't work, you mght need to turn the set off and wait one minute, then turn it back on WHILE the cable box is ON. This can cause the set to RE-Latch onto the cable box signal. It really doesn't sound like something is truly broken or needs replacement, sounds more like a user error. If your set is still under warranty, just call the Panasonic hotline (find it in Google, and they may be able to walk you through exact instructions for your model). Hope this helps.
go to the options with the remote on your tv, then do a channel scan. it will scan for any channels you are picking up. if you have basic cable you will only have a few HD channels. if you have a cable box then the cable box should show you what channels are HD
U get a channel numder and menu screen do show up?Not the tv,it the incomming broadcasting signal cable plug in or the cable box itself have problems.Tries unplug,replug the tv and the cable box back in like about an hour later.The tv will reset itself to the factory setting and the cable box should upgraded it softwares.Should work now.If have the same problems,tell the cable company change the cable box or check the incomming broadcasting cable wire with another tv,see the incomming broadcasting signal cable wire,with a new cable box,see if it work.
I called TimeWarner Cable tech support, and the solution is to unplug the power to the box, after 1 min plug back in, let the box reboot, and PRESTO, this time around, the guide should be working. Note--this is a solution for the problem of online guide that is showing No Data in the boxes, but is bringing up the grid of times/channels/date. If you can't get the Guide at all, I don't know if this solution works. Good luck.
the best from what i seen is HDMI, DVI, or comp. in that order. On my 82" HDTV i use the VGA plug connected to P4 3.5ghz. everything seems to come to life using a computer and good video card.
