Introduced in 1986, the Casio TV-2000 is a passive-matrix 2.7" color LCD television that runs on four AA batteries, a 6V AC adapter, or the optional but rare rechargeable Nickel-Cadmium battery pack. It accepts both analog VHF and UHF over-the-air transmissions, and as such, the discontinuation of analog transmissions has since turned pocket TVs like this into mere collectors' items.

To be able to view the picture, one can either shine an external light through the white translucent panel on the back of the LCD assembly, or use the optional BL-2000 backlight unit that clips to the back of the LCD assembly. On the front of the unit are controls for screen brightness and sound volume, while the right side of the unit is home for color and tint adjustments, and jacks for 6V AC input, external antenna, mono headphones, and an audio/video input in the form of a 3.5mm jack. In the back is just an average telescopic antenna, while the power switch and digital tuning controls are on the top of the unit.

I bought the TV-2000 in 2004 for $5, but only decided to showcase it more recently. The color bars test pattern seen in the upper right corner was injected from my computer by way of an inexpensive VGA to Composite and S-Video converter, and then running into the TV using a standard 3.5mm to Phono adapter cable in the aforementioned A/V input. I also used a daylight LED lamp as a backlight, as the cold-cathode-based BL-2000 tends to drain batteries 50% faster than using the TV without it.
