Summary

Any seat in the house is a good one with this flat-tube CRT TV featuring realistic stereo sound and easy component hookup. True Flat picture tube greatly reduces screen glare while increasing viewing angles. Front-panel A/V input for easy connection of a camcorder, gaming system, VCR or DVD player.

Manufactured by Orion with a full set of inputs. While it has the same shaped cabinet as the RCA 27F554T, the chassis is different and has more in common with the Panasonic CT-27SC15.

Notes

Unlike some other TVs made by Orion, you can change the video inputs using the channel up/down buttons on the front panel. A remote is needed to access the on-screen user menu.

There is a VM coil on the neck of the tube but it is not enabled/connected to anything.

Internal pot VR401 is for vertical position.

Repair Notes

Vertical foldover was occurring when first turned on due to C407 having high ESR, 100uF 35V.

Composite 240p Performance

For composite decoding this set uses the Toshiba TC90A45FG, a 2-line digital comb filter introduced in 1997. Dot artifacting ranges from moderate to severe, blending effects may be broken, and edge artifacts are mostly moderate to severe. An example of the many dot artifacts are highlighted in the picture below in red. If the set has a higher bandwidth input such as s-video or component, then using an external notch filter to decode composite instead and sending that to the set would remove nearly all dot artifacts, blend all dithering patterns, and reduce edge artifacts (guide to using an external notch here).
