Question ID: 127466

I'm looking for a portable TV tuner, battery operated, that I can
hookup to my portable DVD player.  In other words, the TV tuner needs
to output a video and audio signal, via RCA plugs or 1/8 inch audio
cable, so I can input the signal to my LCD monitor on my DVD Player.

They make several of these types of devices for computer monitors and
computers, however I have not located one that is battery operated.  I
have located a Citizen M329, which is exactly what I need; however it
only works on the PAL Broadcasting Standard (Japan) instead of the US
Standard NTSC.

At this point I would even except instructions on how to remove tuners
from portable TVs so could use it with my DVD player.  (It seems all
Portable TVs only have a video-in port and not a video output.

Good Luck!

Hello ingold_ncsu-ga

I started the research with a high level of optimism that I would be
able to find (quite easily) a handheld TV with a video out, or a tuner
unit used with camcorder screens. It soon transpired that this was
going to be a tricky one!

I found a promising link at where the author has the same idea
as you.
but the recommendation for the hardware:
and link to purchase it at for $98 
resulted in deadlinks!
I searched the manufacturer's site, but now only PC card tuners, and
the dgme site totally vaporized. I searched to see if any
second hand ones were available, but no luck.
No luck either on the NTSC version for the TR30
( )
and these 'high end' examples also did not have that elusive AV out

However I did find one method to get you a TV signal.
Not as elegant as I would have liked, and I only posted it due to the
fact you mentioned at this point you would even accept instructions on
how to remove tuners from portable TVs to use with your DVD player.

I sourced this portable battery powered tuner with video out:
GBA TV TUNER (NTSC Version) @$67.00
"Product Features:
- 99 TV Channels
- Channels can be stored with the GBA TV Tuner software.
- Telescopic Antenna
- Antenna IN Jack (to connect an external antenna)

- Earphone / Speaker out Jack

Technical Specification.

hour rechargeable and 90 minutes for normal alkaline batteries

monitor mode
-  DC in jack: attached a AC to DC adapter (output DC 5V
regulated,800ma, central point negative), different versions available
: Japan 100V version or US 110V version or England 230V version or
Euro 230V version
-  Antenna : attached a 68cm telescopic antenna

TV Tuner software)
-  Both PAL and NTSC video input acceptable (monitor mode)

The box showing GameBoy Advance TV tuner with AV out to TV monitor,
and "AV IN/OUT" socket on top of unit

To convert the mini plug to RCA connectors you will need something
similar to these cables
"Triple AV Cable with 3.5 (1/8") mini plug for composite video and
stereo audio to mini plug interconnections."

If it needs a GameBoy Advance to function as a whole, (the GameBoy
Advance probably controls the function of the socket from 'input' to
'output' and also may provide the interface for the tuning etc) it is
priced at $69.95
- Prices from

Total price for this hardware combo: $67.00 + $69.95 = $136.95

It maybe slightly strange why you would feed the signal to your DVD
players TFT, but one major reason for doing so is the LCD display on
the GameBoy Advance is not illuminated with any backlight.

The other (expensive $489.00) quality solution I found was the

"ICOM's new handheld, battery-powered IC-R3 Video/Audio Receiver
- Telescoping Antenna
- 2" TFT Color Display (with 8 user-selectable background colors)
- On-Screen Receiving Frequency
- On-Screen Tuning Step
- On-Screen Memory Channel Number
- On-Screen Signal-Strength Indicator
- On-Screen Bandscope
- On-Screen Battery Voltage and Power Remaining Indicator
- NTSC and PAL Video Signal Compatible
- Receiving Frequency Range -- 0.495MHz to 2450MHz (816-901MHz blocked
on USA models)
[ So TV channels 17 to channel 70  - ]
- FM, AM, WFM, AM-TV, FM-TV Receive Modes
- Receive TV Signal from Local Channels
- 450 Channel Memory (9 banks of 50 channels each)
- Built-In Attenuator
- Auto Power OFF Timer (power save function)
- Backlit Monochrome LCD (with auto OFF timer)
- Monochrome LCD (when color LCD turned off)
- Small Size (2.5" x 4.75" x 1.25") -- Lightweight (10.6 oz.)
- 3.7V/1650mAH Lithium Ion Battery Pack (included)

NOTE:  To download audio/video from IC-R3 [the unit] to VCR (for
recording), order IC-R3-25 Audio/Video Output Cable with RCA Plugs
(25' lead).

For the future, Sony are rumoured to be producing miniture TV tuners
for PDA's about the same size as a postage stamp!

Search Strategy:
Google search string - "TV tuner" ntsc batteries
Google search string - av plug RCA convertor
Google search string - sony pocket tv
Google search string - battery powered tv tuner OR receiver.

I hope that helps, if you need any clarification of the answer just

Kind regards

GoVideo has an attachable TV tuner for their DP 7040 mobile DVD
player. It's the GoVideo dpt100 optional tuner.  The cost is $50.  If
it could be hacked, you have the product you were looking for.
