My new Alarm Clock TV

[Wageslave]

I recently purchased a Sanyo 3T-57 Alarm Clock on eBay, and have been cleaning it up for use in my office. It has a fairly sharp picture and after adjusting the internal pots to resize the screen, works nicely with my Roku.

Does anyone know much about this set, as far as general quality or possible trouble points to keep an eye on?

Thanks
