Summary

A great little set by Samsung from 2005. Uses an unconventional 16" viewable tube. (There is a later variant with the same chassis that was made in Guangdong, China.)

Notes

16" is a wacky size for a CRT TV, but I speculate that since Samsung had made PC monitors of the exact same viewable size, they may have merely repurposed the glass molds of those tubes for TVs.

Component video quality is quite clean, save for the annoying red push. You will have to turn down the color saturation and perform a white balance to remedy the issue.

This set is confirmed to support 50hz. There is a screen option in the menu to stretch the raster vertically, and that may be useful for some PAL games with a squeezed picture.

There were two 16" tube models Samsung made, and the one in this model is a slightly lower pitch compared to the one in the TX-P1634. Still looks quite nice, all things considered. Whichever 16" model you come across, you will be having a good time. In my opinion, the chunky mask on these sets is ideal with 8-bit and early 16-bit content.

You can access the service manual using any compatible remote - turn the TV off (standby mode), then Press "MUTE 1 8 2 POWER". In the standard menu, I recommend using one picture preset for component, and the other for composite.

Repairs & Mods

These 14" and 16" sets of this chassis tend to have a raster that doesn't fill the entire horizontal width. Perhaps Samsung wanted these sets to display the full width of NTSC or PAL video, but not the differing pixel clocks of retro games. Or who knows, maybe it's a design flaw. In any case, the solutioon is quite simple:

For the horizontal width capacitor, the default value is 224j (0.22uf), so replace it with a 154j (0.15uf) cap.
