JVC 55" Rear-projection TV

May 04, 2012 28 Replies

Our 18 year-old rear projection TV (JVC 55" Letter-box) has finally failed... or not quite... the blue sweep only, dips dramatically in the upper middle of the screen making for some garish looking pictures... particularly on old B&W Hitchcock re-runs (playing here w/o commercials ;-)



So I bought a 55" LCD (LED-backlit) at 1/4 the price of the original.



The new set weighs 40#, the old one is so heavy I can barely lift one end. I had visions of throwing it on my pick-up truck and taking it to this weekend's hazardous waste at the local park. But I'd need a couple of moving-company-strength assistants.



Anyone here in Arizona want it?



If not I'll bust it up and dispose in liftable chunks.

Throw in on craigslist or whatever and get fifty bucks or something for it. Or even give it away. It has a convergence problem and can be fixed. But if you bust it up you them waste the pollution caused to build the thing.

Plus the fact that those things are ten times more reliable than the new stuff so someone without alot of money could have it for a while.

Here it is, broken open, a couple of hidden screws "assisted" by force ;-)

Anything there worth saving?

I see some nice heatsinks.

The "screen" _is_ a grating (Fresnel?). Is that worth anything? ...Jim Thompson

It'd make a bodacious oscilloscope for your local technical museum.

Copper is just NOT that expensive yet. And, don't see any gold.

Hook up wire from the harness. :-) Ed

And don't tell me, the new set picture is MASSIVELY better than the old one even on its best day. Try Craig's list and then dismantle it. RIP JVC. Why didn't you replace it sooner?

That's going three pages deep on ebay.

Some have a frame built and installed. Mikek

Good grief, you think there's enough timmers in there?

I counted - I saw 115 trimpots on that one board. Damnation!

However, it is a scavengers dream. Lots of well marked VLSI chips on there.

Maybe an astronomy club would want those lenses.

They would be nothing like diffraction limited or monochromatic so the best bet is to donate them to the scouts for fire starting with the sun.

I suspected they might be good for something. ...Jim Thompson

Note that there are only two CRT's shown... the third was the failure mechanism... leaking oil ;-) ...Jim Thompson

Glycol based coolant. That was a common failure, and fairly easy to fix.

You can't have a sense of humor, if you have no sense.

And optical interface between CRT face and lens... cute! ...Jim Thompson

Another problem with it was something growing in the coolant, witch causes it to run hotter, and affecting the focus or having a dim area in that color.

Too late now. :)
