I like the LCDs. Go look at them at Best Buy, etc. The Samsungs seem nice for the money. Get the most resolution that you can afford and progressive scan.

Not my field (I'm strictly audio), so others can correct me...
For nominally same size TV:
LCD cheaper than Plasma
LCD lower power consumption than plasma
Plasma brighter than LCD at the bright end
Plasma shorter life than LCD
I've forgotten which has the "best deep blacks"
Hope this helps.
I don't expect to buy a flat screen TV very soon as we've just
inherited a newish CRT based 27 inch TV.
Cheers,
Roger

 

lcd 250w constant draw of power due to back light plasma varies with
brightness over all very close to the same in power use

lcd better in bright rooms plasma for the rest

Panels in both (panasonic) rated at 60,000 hours

plasma contrast ratio 10000 to 1 lcd 5000 to 1 plasma produces better
blacks

 

What size?

Under 32 inch LCD 1080p

Over 32 inch Plasma 1080p

IMO, get a tube model or don't pay much and look at the warranty.

 

Hia Frank,
I am a technical advisor, and have been a workshop (TV) engineer for
over 30 years. The info you have already been given seems to be
correct with regard to the power consuption etc. Plasma is better for
dark/black detail, and better for fast action as you may get some
delay artifacts on LCD. Lcd has a higher pixel count, thefore has
finer detail but at the viewing distance required (about 10 - 15 foot)
you probablt wont notice the difference. The best advice I can give
you, is to go to a large store such as Comet, where they will have a
lot of sets on display, and you can make your own judgment. The
branded makes such as Panasonic, Toshiba, Sony, Sharp, Hitachi, philps
etc are probably better than own branded makes, but that depends on
how much you want to spend. I think Panasonic are probably the best
for Plasma, and Toshiba or sharp are excellent LCD sets. One thing you
must bear in mind that, when you get such a large display, you are
blowing up (like a baloon) the same definition therefore the
definition is not as good as a small set. These sets are crying out
for HD (high definition). Ask the store to show you a set running in
HD. I think you will be amazed! Bear in mind that the only source(s)
of HD are a dedicated HD player such as Toshiba or Sony do, the former
costs about £350 and has the HD DVD format. Blue ray is the other
format, and has more film rights, hence most of the new films tend to
me Blue Ray. Blue ray players are more expensive, but the new Sony
Playstation 3, has a blue ray player built in. The film itself has to
have been recorded in HD, but these players are backward compatable,
and will play normal DVD's.
They currently cost around £15 a film in HD. The other source of HD is
Sky Plus, but please bear in mind that only a few channels transmit
true HD. You should make sure you use an HDMI lead for HD. You can use
component video or DVI, but these last two require seperate sound
connections.

Hope this helps

Your advice is best I have seen sofar!

One thing I would like to add, is that I found that rear screen
projection sets are not that great. They look soft, and the replacement
lamps don't always last very long, and are very expensive. A few people
I know bought a rear screen LCD projection TV because they like the
size. I found it to be a bit soft compared to a standard front view.
They also learned the hard way that about every 6 to 8 months, they had
to replace the projection lamp. This lamp is over $200 US! The TV is
used every day for most of the day.

As for LCD screens, I also found that with age, they do not drift in
colour temperature. After about 60,000 hours the backplane lamp and its
power supply may burn out. But, after that many hours, I would be
looking at replacing the set rather than servicing it. There are many
other types of components that can die in a TV or monitor after many
hours of use.

hia Jerry,
what you say about projection tv is quite right, thats why I didn't
recommend them, that also is true of DLP sets. While Plasma sets give
a higher light output (being an active light source, as against LCD)
LCD are getting better, I recently looked at a plasma and lcd side by
side, and to be honest, I could not see any difference, but this was
not a critical anaysis, more from just watching them as a customer
would. I would advise taking out extended warranty on both plasma and
LCD, especially the large sizes, as if the display panel fails, they
are VERY espensive to replace!

Regards

Rod

correct.

The following is from today, opied from a thread on another forum:

i was shocked this week when a toshiba 32wl56p came in for repair it
didnt take long to diagnose the fault to the inverter pcb having
failed
so as usual next action was contact toshiba for price couldnt believe
it when they told me the sharp manufactured inverter/lcd panel was
only available as a complete assy at a cost of about £500 plus vat
this has also happened with other manufacturers ie daewoo philips and
a few others i think its outrageous that a £50-100 inverter fault
means having to purchase the whole screen however i typed the inverter
part number into google and to my surprise found a company in the
states (INVERTERCENTRAL.COM)that supplies the inverter it is one of
there most popular ones the whole price inc shipping is $99 which
saved a perfectly good tv although its a crappy lcd from landfill

Default Re: lcd inverter failure
I had the inverter fail on my Acer 17" LCD monitor model AL1711,
identical inside to the 15" version AL1511. I managed to open it up
and found four electrolytics with slightly bulging tops, these were
mounted on the pcb such that the heat from a heatsink rose straight
into them. I changed all four caps and the monitor is now working
well. Worth a check on any monitor really, change those caps with
slightly convex tops! I used 105 deg.C jobs as replacement.

Hi RBM
Many thanks for that. I suppose their theory is that a faulty
backlight tube will damage the inverter. This can be the case in
smaller sets for some reason, but I've yet to find this in large-
screen LCDs.
Mind you, £500 is a good price for a screen - Panasonic and Philips
are around £1000 for a 32" - and that doesn't include the inverter
PCB!

It will not be worth repairing anything soon, John Lewis were selling
Panasonic 37" LCD TVs for about £850 last week with 5 years guarantee,
which makes £1000 for a spare part seem a trifle uneconomic.

John
The only problem with these extended warranties is that if the repair
is considered uneconomical or if parts are NLA then the set is written
off and the insurers pay a fraction of a new set.

 

You Guys are great . Much good info regarding replacement TV.
Friend told me that LG is considered a good product . Your feelings ?
Man buying a new TV is as much a Pain------- as buying a car.

Pretty good. Don't buy 'old' brand names like RCA, Philips - or Singer! No
name brands are better than those.

 

Well those *are* no name brands, with well known names slapped on the front.
They do tend to be the bottom of the barrel though.

 

My theory is that if the sets are really bad they use a rent-a-name to make
them look better than they are. If they're OK they sell on their own without
the label.
