== Overview ==
The '''JVC AV-28CH1EUS''' is a 28-inch 16:9 widescreen CRT television produced by JVC (Victor Company of Japan) for the European market. It is built on the '''MF''' basic chassis and dates from 2002.<ref name="sm">JVC ''Service Manual'' No. 51944, Colour Television AV28CH1EUS / AV28CH1EUB, basic chassis MF, Victor Company of Japan, March 2002.</ref> The set is a 100 Hz design: it doubles the field rate to 100 Hz for 50 Hz PAL/SECAM sources (and 120 Hz for 60 Hz NTSC) to reduce large-area flicker.<ref name="sm" />
Off air it receives PAL and SECAM across the CCIR B/G, D/K, I and L/L' systems, and it can additionally display NTSC (3.58 MHz and 4.43 MHz sub-carriers) through its external AV inputs.<ref name="sm" /> The picture tube has a 66 cm (about 26 in) diagonal visible area and operates at up to 30 kV at zero beam current.<ref name="sm" />
The AV-28CH1EUS is a cosmetic variant of the [[JVC AV-28CH1EUB|AV-28CH1EUB]]. The two are electrically identical on the MF chassis and differ only in cabinet trim and the bundled remote control, which is the '''RM-C54H''' on this model.<ref name="sm" />
== Features ==
* 100 Hz / 120 Hz scan conversion for reduced flicker.<ref name="sm" />
* NICAM and A2 (dual/German) stereo sound, supporting bilingual programmes; 5 W + 5 W amplifier driving two 10 × 3 cm oval speakers.<ref name="sm" />
* Teletext with FASTEXT, TOP (German) and WST (World Standard) systems.<ref name="sm" />
* Interactive on-screen control menu.<ref name="sm" />
* Aspect modes for displaying 4:3 material on the 16:9 screen: Full, Panoramic, Subtitle and Compress.<ref name="sm" />
* VCR dubbing via the EXT-2 SCART line output, which can carry a source chosen on the AV selector.<ref name="sm" />
== Reception ==
Terrestrial tuning covers VHF 47–470 MHz and UHF 470–862 MHz through a 75 Ω unbalanced coaxial aerial input.<ref name="sm" /> Mains input is AC 230 V, 50 Hz, with a rated power consumption of 112 W (average) and 165 W (maximum), and 2.8 W in standby.<ref name="sm" />
