Question about Casio EV-4500 4 in. Portable Television
I am thinking about buying an A/C adapter for my Casio EV-4500 TV, but I am not sure if it is going to work once we go "digital". Does anyone know if this TV will work without a converter box??
SOURCE: I have a Casio EV-570
According to CASIO website in Japanese, their portable TVs are not supporting Digital broadcasting and decided to cease production.
Thus it will not receive Digital broadcasting.
Although, EV-570 composite AV Input should still work for Camera, VCR, etc., I have not tried to connect to the DAC box.
My portable DVD without TV tuner worked with DAC box and now can watch digital TV program!

I have my handheld Casio TV-980 up and running with a
converter box. All I needed (in addition to the converter box and standard
rabbit ears [UHF/VHF] antenna) was an adapter with an F jack on one end and a
1/8" plug on the other (Radio Shack catalog # 278-257, about $5). The
1/8" plug on the adapter goes in the external antenna jack on the TV, and
the other end connects to the coaxial cable that connects to the TV (RF out)
jack on the converter box. The adapter would have been a little cheaper at my
local, independent electronics store, but they were sold out.
If your antenna has flat 300 ohm wire connections, you'll need a balun (Radio Shack catalog # 15-1297, about $8) to connect it to the coaxial cable that goes to the Antenna (RF in) jack on the converter box.
I’ve tried 2 different converter boxes with the handheld TV, and they both work well: Insignia (Best Buy’s house brand, same as Zenith) and RCA (from Target, same as Venturer), so any government coupon-eligible converter box should work.
A few other tips:
1. I always turn on the converter box before I turn on the TV. The cpnverter box seems to take control better that way.
2. When I turn on the TV, the tuner doesn’t automatically go to channel 3 or 4 (where it should be set when using a converter box), and the picture quality is poor. If I use the tuner on the TV to get to channel 3 or 4, the picture quality is vastly improved. I have to do that every time I turn on the TV.
3. Placement of the antenna is very important. I like to watch my handheld TV when I'm on the computer, and the reception is better the further away from the computer the antenna is located. I'm actually using a 6' coaxial cable for the antenna, but I could also have used 2 shorter cables with a coupler that has an F jack at both ends (Radio Shack catalog # 278-304, about $3).
If your battery-operated TV does not have an external antenna jack, instructions for connecting it to a converter box can be found at
There are a few battery-operated converter boxes available, but for do-it-yourselfers, this web page also contains instructions for building a 12-volt converter box power supply.

You can actually plug a stereo headset into a mono jack and it will usually play the audio thru the left ear piece.

The only way is to use a standard "Set top box" or just use it as a video monitor for a VCR or DVD player - It has an A-V input that you can use, but it uses a 3.5mm jack socket (I think) - You'll need to determine the connections, but I'm sure it'll work fine. I'm just researching the conections myself. I'll re-post if I fine 'em.
