Summary

Mitsubishi's finest 26" picture! There's a new standard of excellence in $698 televisions. On this day, Mitsubishi challenges anyone to match the technology, features, and refined audio/video performance of the CS-2657R. This 26" remote stereo tv has an advanced scandium oxide 450-line high-resolution picture tube, with innovation like Diamond Vision II, S-VHS input and stereo sound.

Includes S-Video, side-firing speakers, as well as jacks to power external speakers. Has internal pots to adjust pincushion, horizontal width, vertical size & linearity. Lacks controls for horizontal & vertical position (can be somewhat manipulated with purity rings, but may require a magnet(s) on the picture tube to compensate for purity issues). A downside to this chassis is that it resets picture settings when it is unplugged; as such the contrast will be maxed out unless it remains plugged in, or the user adjusts the picture settings every time it's plugged in. The Diamond Vision II tube uses scandium oxide making for a high current cathode.

The jungle chip does not have RGB inputs, but S-Video is already very sharp.

Repair Notes

One specimen had a loud hum in the left speaker caused by an open feedback capacitor C3C2. The brown adhesive used to hold down capacitor C773 was found to be significantly corroding the components it came in contact with on the main PCB. There was some minor upper pincushion, made more prominent in the presence of red.
