What specific model of JVC multi-system TV do you have? What is the signal source?
The majority of the JVC multi-system TVs that I've researched only have analog tuners (NTSC, PAL). The AV-29LX is an example of the older JVC TVs. Since most over-the-air signals are digital, you will need a digital-to-analog OTA signal converter to watch any signal from an aerial TV. If you have a cable system that has upgraded to digital cable, you will need a cable box.

(A few low-power stations still broadcast in the analog format. However, you have to be really close to the station or have an outdoor antenna to have a chance at receiving the signal.)
Digital tuners for over the air signals are called "ATSC tuners".
To tell if your TV has one:
-If the TV was sold as a "HDTV" or "DTV", it's supposed to have an ATSC tuner built in to it. "HD ready TVs" do not have a digital tuner.
-Check the specs in the owners manual or google the make & model of the TV to see if it has an ATSC tuner.
-If your TV's menu has an option for scaning for digital channels, then
it has an ATSC tuner. If it dosen't have a way to scan for digital
channels, then it doesn't have a digial tuner.
Most DTVs also have a digital QAM tuner that is used in some (but not all) cable systems.
You need a new TV if it does not power on? If the JVC TV power on, you need a new UHFantenna for DTV converter. If the problem is beyond antenna or DTV converter in the US, time to buy a new TV.
if you are going to continue using the rooftop antenna, then you will nee to purchase a digital converter box. Those television sets are only analog. You do have an option to get Directv or Dish network and you will not need a converter box at all. Directv and Dish network are 100% Digital and the receivers work as converter boxes for that product only.
