Hello,

I am an electronics techo, dont work on TV`s that often but have had some
experience mainly friends family etc... have not worked on plasma screens so
im after some help/advice if possible.
The above unit has sound but picture died while watching it ( its not mine)
Unit is15 months old (warranty 12mths) , bought from Kmart apparently

Owner has been advised by phone (repairman has had an educated guess i
suppose)
that it probably is the microprocessor a new one would cost about $800,
would this include labour for fitting

Some questions
1. Would it be worth pursuing Sanyo??????


2. Can anyone provide me with a service manual and or schematic or details
of where to get one?


3. Have no reason to doubt repairman but $800 for a micro ?? would that be
right and while im at it
what microprocessor is it ( after a datasheet possibly)


4. Any other help/advice would be appreciated



thank you

Steve

I used to work with a Steve Butler in the old Telecom radio
communications section. Just wondering if you're him? :-)
There's a fair chance you can hire a service manual from High
Country Service Data; see http://www.hcsd.com.au/

Chances are the micro itself is a custom part and is not available to
ANYONE - including an authorized repair shop.
The usual repair process involves using the service manual - if you can
get it - to determine which circuit board has a fault and replacing the
entire board. Cost could be $400 to $1200 for the board depending on
which board it is. They don't make it easy or cost effective to do most
repairs.

Forget about service manual. Serously, you may be able to get wiring diagram
if that. No component-level repairs on plasma, just board swapping.


Most likely you will have to replace Y-sys, Z-sys and control board as a
kit.

Where are you physically?

why not pull it apart, and try and figure out what has died. ISTR they
have a fair bit of power electronics in them, that would be a good start.

If they were in NZ, they could simply take it back from whence it came,
and demand a repair/replacement/refund, under the Consumer Guarantees
Act - 15 months is NOT an acceptable lifetime for a TV set, regardless
of what the warranty says. Besides, if it dies after 15 months, the
problem is most likely manufacturing and/or design.

Cheers
Terry

I am in Perth,

Bob .......a different Steve Butler im afraid, HCSD dont have a SM , no
support as Rudolph mentions

Have to see which board it is and price a replacement i suppose

thanks for your help guys,



Steve

I wish this would be a single occurence....
I have lots of plasmas just out of warranty. Sometimes repairs are quite
expensive. For example, new power supply board for HITACHI 50" plasma is
$1300 trade.

As long as consumers will insist on buying cheap stuff, they will get crap
quality. You get what you pay for.
And then all this junk just ends up in landfill.

I do warranty for a few companies and I am unstructed not to accept DVD
players in for warranty repairs! They are being swapped over in the shop and
faulty ones will eventually make their way to our landfills.

Lost of people do not want to fix their older equipment, because new ones
are so cheap, it makes repairs not economical. Electronic companies have to
go with that and make their stuff as cheap as possible, cutting all corners
they possibly can. It is not fault of the manufacturers, but of consumers
for trading quality for price. So, what are you complaining about? You
wanted to get cheap stuff in teh first place ad expect it to work forever?

(Sorry, had to vent)

I would start with Sanyo but perhaps get some info from consumer
affairs first (Department of Consumer and Employment Protection)to see
what exactly your position is.

As Terry said 15months is not an acceptable expected lifetime for such
a product. Sanyo should repair or replace it for you.

Well written, Rudolph!!
Unfortunately the consumers have no idea how many corners were cut so
that they could have this marvellous technology so cheap.

Bob

hear hear. years ago when I was a videogame tech, I made a small fortune
(not really, but it felt that way at the time) fixing smps. They were
very cheap, and the most common fault (80-90%) was the input rectifier -
Ifsm was about 30A, and they had a 1R series inrush limiting resistor. I
fixed several hundred, for a flat fee of $35. All I did was replace the
(usually gone) fuse, and stick in a much bigger bridge. $5 parts,
typically 5 minutes to repair.

On a related note, I bought a 10A plug board while in China last year,
for my lap top etc. The nz/aussie plug kept falling out of the wall
sockets, and I erroneously assumed that the wall sockets there were
****e. When I got back to NZ I had the same problem. The cause? The
prongs were 0.8mm THINNER than a standard plug, thereby saving material
hence cost.

So I chopped the plug off to replace it with a tap-on, and discovered
the 10A mains cables had perhaps 5 strands of fine Cu, and a lot of
insulation. 10A? more like 1A.

So much of this cheap crap is exactly that, but it *looks* like actual
things. Caveat Emptor.

I was talking to some chinese people and theye all were saying that stuff
made in China for China is pretty good quality, comparing to exports. Why?
Apparently, because consumers all over the world demand "cheap stuff", not
"quality stuff".

An interesting experience I had some time back -- I needed a small
philips-head scredriver. I used to do a lot of video cameras and those "made
in china" scredrivers that you can buy everywhere for a few dollars did not
last more than 1-2 cameras. So, I wanted to get a good quality one and was
prepared to pay for it. I COULD NOT FIND one that was not made in China!!!

It tok me about 2 weeks to find a supplier here who had German made ones.
Cost me about $15 for a single scredriver and I still use it.

Whats does it tell me? It is the consumers who drive the quality down.

Yo can buy a TV now for $199. After warranty is gne, it will be thrown away
and then what? You will go and get another one for $199. Why not to spend
$400 in the first place and get a unit that will last for years?

Just my 2.2c, (inc. 10% GST)

You can check the price of electronic gear (including TVs) and get a broad
range of prices for the same product. Most people will choose the cheapest
price.

The reason why consumers don't spend $400 is that they usually have no way
of knowing whether that $400 product is any better than the $199 product.
And, in many cases, the $400 product is just a rip-off.
