The CRT-RPTV
The old venerable, still impressive, and CHEAP CRT-RPTV (rear screen projector!) Retired soon!
A big and heavy beast. One that's losing market steam. Sure as summer follows spring, the CRT will be edged out by the newer technologies. This is both a curse and a blessing. A blessing because, if you buy now, you get a terrific price AND you buy this technology at its peak - it isn't likely to get better, and it has come a long way.
A CRT-RPTV High Definition rear screen projector is a bargain!But you need to know that after a while - say, every few years - (and perhaps right out of the box,) the set should be converged, i.e.: the three color 'guns' should be set so they exactly overlap at every part of the screen for crisp high resolution. Have you ever seen a TV where there were colored edges to things, maybe more as you looked toward the sides or edges of the picture? That's misconvergence. Some TVs have auto-convergence. Look for it.
Bonus! CRT-RPTVs tend to get analog "standard" TV more right than other technologies. In comparing, if you do, even knowing how badly setup TVs are in a store, try to get someone to show you standard NON-HI-Def TV and notice which set looks better. I bet it'll be a CRT based one, either direct view or rear screen projector.
Also notice how they won't likely want to SHOW you the bad picture on their more pricey HDTV Plasmas or LCDs or DLPs.
Did you know that RCA actually had what you might term a black and white RPTV back in the 50s?
Sidebar: A good friend of mine was an early adopter of a rear screen projection TV when they were becoming popular - I'd guess this was the late 70s or early 80s. We'd go over and watch this LARGE SCREEN and get headaches. "Isn't it great?" he'd ask. "Do you have any aspirin?" we'd reply. If that's similar to a memory you hold about these displays, good news - they've come a long long way.
CRT-RPTV Plusses:
Cheaper than the other displays
Great picture; especially with old standard TV broadcasts,
This technology is at its peak
CRT-RPTV Minuses:
Size
Weight
Obsolescence
Depth
Convergence necessary
Speaker shielding issues
Lesser viewing angle than direct-view CRT
Certain images can burn in (for example: aspect ratio bars of 4:3, video games, logos, stock crawls).
OPINION:
If money is tight, you can save thousands and still have HDTV with a CRT RPTV.
