Plasma TV (and the death of projectors)

what they don't tell you is that these bulbs die with an explosive bang loud enough to make you think you're taking mortar fire.
Is this common or does it happen only in certain conditions? Depending on bulb quality or environment in the room, things like that. Best warn my brother just in case though, his has been in place for a year or so now.

This was an InFocus projector, and it happened 2 for 2 on the bulbs. Only the second explosion caused powdered glass, but once is enough for me. Can't speak to any other brands.

I can attest to this. We had a teacher almost have a heart attack due to one of these going while she was doing a presentation in a lab. 2 students were showered with the dust. Not a happy day for our IT director who had to explain why his projectors were suddenly time bombs. It happened again the next week (that one gave a grade school kid nightmares) and I quietly replaced every bulb the week after that on all the remaining projectors of that shipment. I wonder if any of them remember all this. Heh, might be fun in that place soon since I figure they will start going in November.

Avoid plasma screens, there's a reason they are much cheaper than LCD's. The quality as absolutely crap IMHO. And another thing, be sure to get an LCD that says "Full HD" instead of "HD ready"

I wired an Electrolytic Capacitor in backwards once, it was a big one too. The Boom from that was like a bomb going off.

Why am I scared at the radioactivity of your tv set? With that short of a half life it has to be dangerous...

What's the difference between Plasma and LED technology?
Christopher Duncan www.PracticalUSA.com Author of The Career Programmer and Unite the Tribes Copywriting Services
'LED' is LCD with LED backlighting instead of a cold cathode fluourescent lighting. It's still a transmissive display and whilst LED backlit LCDs are very good if you want GOOD colour plasma still wins.

I agree because I watch a lot of HD programming/Blue Ray disks/HD gaming but... ... if you watch non HD broadcast quality or standard DVDs (and don't own a XBox 360 or PS3) then you can get poorer visual performance on Full HD as it has to fill more missing pixels to fill the screen. For many people who rarely/never watch HD broadcast/recorded material etc, "HD ready" can be a better choice.

That article cracked me up. I thought it would be a polemic on the consumer culture; instead it was interior designers whining (probably the same people who fill rooms with gauche furniture without regard to use.)

And at that interior designers have much worse things to be pitching fits over. My sister's friend does it for people with stupidly much money (her record is $100k for a stove) who'll blow $10k on a Lucite bed frame. For those of you not in the know, Lucite is a different band name for the same thing as Plexiglass; what rednecks use to fix broken windows. :laugh: :laugh: :laugh:

There are also two kinds of LED backlighting, one with channel groves and the LEDS on the edges and the other with a 2D array behind the LCD elements - there is a good explaination of the differences here (see #4)[^]

Yes, a guy at work bought an edge LED TV - not quite as good as the rear LED but personally I found it better than CFL. LG are very competitive on LED and plasma these days.
