I am a little curious. Has anyone run into a plasma display that needed
repair. I assume they can break. What is your experience?

joint at one of the connectors you could repair it, but generally the driver
boards that are part of the panel itself fail, or the panel phosphors become
burned so the image looks bad, for the most part there's very little that
can be repaired on a plasma display.

Uhhhhhh, not exactly.
There are quite a few things that can go wrong on a plasma. Screen burn or a
crack is unrepairable but just about everything else can be repaired. I've
been doing them for about 4 - 5 years and have seen quite a bit. We just
invested about $500K in a bonder so we can service the drivers and ribbon
cable that's attached to the glass screen. I also service the boards with
the PDP.
The japanese manufacturers want the world to believe that they can't be
repaired but the US branches such as NEC USA, Matsushita USA, Pioneer USA,
etc believe they can. We're proving this now and it has caught the attention
of these US branches. So much so that they've authorized us, and only us, to
repair plasmas to this level. Our repairs focus on the PDP component itself,
boards and glass. A panel that has blocks or areas blacked out or of color
had to be replaced at the cost of a new panel but we can repair/replace the
bonds or ribbons that cause these failures for a lot cheaper.
We've just received the equipment a week ago so I don't believe it's on our
site yet but you can check us out at www.itproducts.com or you can e-mail me
at chrism@NSitproducts.com but remove "NS".

I have been working on em for about a year and most times it is something
relatively cheap. Anything beyond I/O and PWB boards gets pricey. If the PDP
is cracked throw the thing away. Most times the plasma thinks something is
wrong and just requires a reset. (I had a guy who had a plasma on a house
boat. A few days in the thing stopped and gave a cracked panel error. I
figures it was from the boat swaying and what not, decided to give it a
reset and viola. It worked. Guy called me two days later with the same
problem. Basically sold him the info on how to repair it and told he was
responsible for anything that goes wrong)

Well, if if is just the glass that is broke, very cheap fix with a little
skill needed. But if the Plasma Panel itself is cracked they are realizing
that with labor and parts it is cheaper to uy a new or used one.

So what you are saying is that if you are willing and able to invest
1/2 a million dollars in a specialized bonder they can be repaired.
Still not a practical or cost effective thing to repair for virtually
everyone.
To meet the break even point you would need to do 10000 repairs that
netted a $100 profit that required that bonding machine.
How many do you see a year in your city of how large?
I am pretty certain there are not even 10000 PDP's in our city total
in use yet.

We're doing them nationwide for most of the mfgrs so it doesn't matter how
many are sold around here. But if you want to know, I'm in central Florida
and these plasmas are very popular around here, especially with the tourist
attractions. DV is also pretty popular around here, too. I specialize in
these pro and broadcast products as well as most everything dealing with HD
or digital as well as customized electronics. Keeps me busy.
Yes, the equipment is very expensive but there is a market and a call for
this service. With the support we're getting from the mfgrs, I believe it'll
pay off.

So what does the insured special shipping cost for someone to ship it down
to you?
Say on one of those $13,000 Pioneer HD units from about 4 years ago.
That is a pretty sizeable investment and I hope it does pay off for you.
It has been my experience though that the price of new technology
continously drops, making for less profit on each successive repair. I do
not see the larger PDP units going much below $2000 for a few more years
yet. Although $3000 seems to be the going price for a 42" one already. You
should have enough years of higher profit repairs to at least pay off the
bonding unit.
I am curious how many a month you are seeing that are repairable with the
new machine.

Andy,
I can tell you from experience that if I could have found a broken Sony 42"
about 6 months ago it could have salvaged a job I was doing. The video board
was wholesale at $1400.00
Most complete board sets for these could easily double or triple the
$500-$1000 investment as a parts source alone, and then more profit from the
labor on top of that.
Good Day,

I don't know the price of the insured shipping but it looks like it's around
$150.00 for the mfgrs. It really depends on the shipper, distance, and
quantity.
As you said, the price is coming down on some units but, as you know, you
get what you pay for. The cheapies sacrifice brightness, contrast, and/or
resolution. If you put a variety of them side by side and drive them with a
high def signal of 720 or 1080 lines (not 480) then you'd see a definite
difference. Life span is another consideration. The cheapies have a
considerably less life span than a decent one.
The estimates we're getting from the mfgrs as to how many we can expect to
see seems to be around 50 per month per mfgr. This number will increase as
more are sold. Right now I'm seeing about 20 - 30 per month with about half
of them under mfgr warranty. Of the defective panels that aren't cracked,
almost all of them require rebonding or drive tab replacement.
The machine can handle up to an 85" panel so we can repair any panel
requiring bonding on the market today. We chose this size because this will
be the biggest panel available real soon if not now. PlasmaCo, a NY based
company partially owned by Mitsubishi, will be producing this.
Our target customers are mfgrs and service centers but we won't turn anyone
away. This a new market that we will agressively persue.

Let me tell you all.
PLASMAS SUCK ASS!!
They look great, very pretty, and do wonderful things. But in just the last
year of seeing them take off and selling plenty of them to clients, I have
had nothing but problems and complaints with them. Burn in is the biggest
threat. Even with a screen svaer or oribtor function these damn thing
burn-in in a matter of 15-30 minutes. Repair is fairly easy, but disassebly
requires at leats 30 screws, and parts are very expensive.
LCD is the way to go. Wait and the price will drop. They have a much better
image quality and last much longer.
THANKS

15 - 30 minutes? I don't think so, unless it's a super cheapie. If screen
burn is such an issue, how come some have life spans up to 40,000 hours? LCD
is somewhere around 55,000. As for LCD, put one next to a decent plasma and
tell us how much better it is. Or display a 720 or 1080 line HD signal with
some action and tell us how much more hesitant the image on the plasma is.
That's right, a plasma doesn't have that problem. Or maybe viewing angle and
the shading and contrast problems while viewing from a side. Oh wait, a
plasma doesn't have that problem either. Hmmmmmmm. How sure of you of this?
I think you're exagerating quite a bit. My personal one is about 6 years old
and still has a picture that'll blow any LCD away. You have to be a little
more careful with it but it's no real hassle. Just make sure it's off when
not in use and view HD as much as possible. Is this much of a hassle?

minutes, the chances of this are reduced considerably if you set the
brightness and contrast properly though, there's several DVD's available to
assist in calibrating your whole setup. Newer plasma panels also generally
have added circuitry that shifts around pixels that are static to prevent
phosphor burn, LCD's are still FAR more resistant to it though, but then you
have the backlight tubes that can fail and it can be difficult to source
ones of the correct size and color temperature. Both formats have advantages

Put an MSNBC logo on any plasma and watch it for 30 minutes. Chane the
stations and tell me what you see. A nice permanent MSNBC logo. Just the way
Microsoft would like it. I only deal with high quality plasma displays (NEC,
Panasonic, etc) I have taked a NEC 40" LCD and put it right next to a 42"
NEC plasma, fed them both the same types of signals and LCD is better.
Consumer models are all the same, low quality parts and you wont see a large
differance in quality from one to the other. Like Chris said, both have
advatages on eachother. He also said DLP is pretty nice. It is. I own a DLP
and an LCD projector at home, and side by side the DLP has much better color
and contrast ratio, but the LCD produces a much sharper image. I guess it is
all personal preferance.

Look into JVC's line of D-ILA projectors. It's a type of reflective LCD.
What this means is that you don't see the drive transistor as you would on a
standard passive LCD. Instead, the transistors are behind the liquid crystal
and is reflective rather than passive. A clean image without the blockiness.
Their only real downside is alignment and light output, both caused by the
nature of the polarized light. Alignment isn't an issue if done correctly.
Light output is at best 70% of the lamps output. Price is another issue but
if it's quality you want then.......
