Question: Does this TV have build in digital tuner?  We don't have cable but would like to hook up antenna to catch the local channels...without convertor
Document: Very smooth motion, without the blurring you see on some LCD sets. Very impressive picture.The sound from the TV speakers is not great, but I guess that goes with the territory with flat screens these days. You will want to hook it up to a sound system (but don't forget that this set only has an optical digital audio out jack).I would recommend this TV, as long as you do not need to connect many components to it.
Never exprienced that with my Panny. I could, however, feel the itch...Enter Amazon's ridiculously good deal on this 50 inch 1080p set, which was basically just $100 more than I paid for my 720p set over a year ago. Had to, had to, had to. Met the delivery guys on the porch, ready to get this baby hooked up as quickly as possible. At first, I was disappointed, because the digital cable channels looked about the same.
I may be biased towards plasma TVs, but the P50U50 looks as good as any set I have ever seen. We have used it for movies, OTA HD, digital cable, and video games, and it has exceeded our expectations in all cases. I purchase for 599.00 w/ free delivery, and feel like it was a steal of a deal.
I highly doubt you'll find a plasma with a better image for the price. Once calibrated, the color accuracy is quite good, and it's a very dependable, basic 2D TV. No weird compatibility issues, and it easily tunes all the local HDTV OTA stations.However, there are some caveats:1) the lack of HDMI plugs will be annoying if you have more than a few devices to hook up.
This is a GREAT TV!BUT... Here is the problem:Panasonic has cut back on the number of jacks on the back of the set. There are only 2 HDMI terminals, 1 set of composite video / audio inputs, and one optical audio out. There is also a coax terminal for a cable or antenna input. But THAT'S IT !!! !Come on Panasonic !
For all the raves, I received a TV that was unusable for watching most sports, particularly basketball- moving players had sparkling halos, picture brightness changing, just awful. Tried all recommended picture adjustments. Two service calls from the local cable provider to insure signal quality, multiple email and forever-phone-calls to Panasonic... finally, Panasonic agreed to send out a locally authorized service person.
I have been using the TV for about a month. I am very pleased with the purchase thus far. Needed to upgrade my cable box receiver to get the full breadth of HD but definitely worth it. The antenna is strong enough to pull in signals from Boston ( I live in Southern NH) so that's a plus should I decide to ditch cable.It is set up in a room with pretty strong back light during the day.
Once again though, I will be piping all the video and audio through my AV receiver to get digital surround sound.+ Great picture quality, especially at this price-point+ Easy setup+ USB and SD slots for additional media viewing; though the kinds of files supported is limited.+ The remote control is decent+ Just love the boxCons+ No HDMI cable included.
This 50 inch set is  big enough and the picture is so much better than my old set, I almost can't believe it. Set up was easy, since the delivery man unpacked it and made sure it was working. All I had to do was hook up the cable box. For the price, this set can't be beat, as far as I am concerned.
I went to a local box store ( B.B.) to buy this t.v., I received such poor service I left the store without it. I was apprehensive to order a t.v. off the internet. Eventually I talked myself into ordering from AMAZON.Today I received my t.v.
Answer: Yes, it has a digital tuner.
