Removal of debris from the Pickup in a CD or DVD device: Use of canned air
(Compressed Air in a pressurized container) is preferred. Open the drawer of
the device, direct the air via the supplied plastic nozzle, and just blow
the debris out of the device. Severe cases of sticky debris can be removed
with a "Q-Tip" and rubbing alcohol, with extremely light pressure being
exerted against the actual pickup.<

However the preferred method is the air "blow off". If indeed you are
accumulating a large amount of debris in a very short period of time it
may be a good ides to evaluate the environmental conditions of use of your
product.

trying to make a sale, or just giving an estimate to a customer. Anyone

Just another $.02 of mine.

Have you ever worked in manufacturing? I worked as a production and
engineering test tech. Lets say I needed a 0805 SMD resistor. Our cost
was a little over 1 cent. On the other hand the paperwork and time to
look up the part number, request the part, have it pulled from the
stockroom and get it to my bench was over $5.00. I finally got
permission to get these parts 100 at a time to reduce overhead. I used
a lot of SMD resistors, so I had over 100 different values of 1% & .1%
resistors on my bench, along with common SMD ICs and a few crystals.

In other words, you have to live it to understand it. You are asking
for a very fragile and expensive part that wouldn't be sold every day if
it was five dollars. It needs special handling at all stages and a lot
of administrative costs, not to mention outrageous taxes on spare parts
inventory. Why do you think companies in the US try to use the lousy
J.I.T. system? It looks good in theory, but leads to shortages and no
spare parts.

The additional costs for spare parts doesn't bother the government
because they are just giving back the taxes you paid, along with the
cost of the part.


It isn't worth 2 cents.

I realize that you have to have a certain amount of markup, to conpensate
for such expenses. But I think that mfrs could probably sell replacement
parts at much lower prices, and still make a decent profit. As someone else
implied, they simply want to make their products unprofitable to service -
and I still think that's the primary reason for such costly replacement
parts.

It is like that for everything when you look at the true cost of the part
itself. They manufactures have high administration and operations costs.
If
something is not moving very fast off the shelves, then its effective cost
is higher.

You also have to consider that when you are servicing your own devices,
the
labour is actually very expensive. A very good skilled tech has to be paid
at least $20 US or more per hour. To operate a business, you would have to
charge enough on top to have the operating costs, taxes phones, a vehicle,
utilities, and administration costs also to be paid. This is why many of
the
service centres are charging more than $50 per hour to work on appliances,
and home electronics. If you look at the total operating costs for a
typical
business, there has to be a fair amount of money coming in, or they would
have to close down.

As for the low to medium end CD players and VCR's very few people are
servicing them. The cost for the labour alone, is just too high to make it
worth it. For the low end units, many of the manufactures are no longer
supplying or stocking replacement parts. It just does not pay.

As for legislation to make price control, this will never happen in our
society. If this starts, this will be the downfall of the way we live.
There
is the aspect of price and demand. If a company starts to charge too
high,
they will find that they will not be in business much longer.

These days the way they can pack things by machine and do it all in
China it does not cost that much to stock parts .
The bottom line is they dont sell those high priced DVD lazers on
porpose and dont even have them in stock because after a 200$ quote
anyone would go buy a whole new player for 45$ .
If someone is dumb enough to pay 200$ for one of those can get it .. One
of the workers at the plant in China holds a coffee cup under the lazer
pooping machine & catches one , chucks it in a box & off it goes .

Do not use alcohal on any lazer lens . use windex

There exists legislation that manufacturers must stock spare parts for
out of production equipment for seven years (or some length of time
like that.) This was enacted in the 80s in response to consumer
complaints that manufacturers were gouging consumers by forcing them
to buy new models when a spare part costing a few dollars would have
kept the equipment chugging along fine for a few more years. The
manufacturer's work around to comply with the law was to make
replacement parts prohibitively expensive. Of course original
equipment is so inexpensive these days that repairs are never worth
the time and effort even if one has the inclination to tinker.

If this was ever true, it isn't anymore. The manufacturers are only required
to support their product for the duration of the stated warranty, and this
can include factory-only repair or just exchanging with a like or
"equivalent" product. (How many computer monitors are imported with NO spare
parts?)

Company policy and market forces are all that determine parts cost and
availability. Certainly laser pickups are overpriced as a rule, but this
just means the companies in question aren't interested in selling parts out
of warranty, but still stock them (or previously did) for warranty repairs.
Eventually they'll sell them in bulk to MCM or somebody else.

<9mm4119j5ov60bch2cmrj64mps05tjhqhm@4ax.com>:

Overview: We have roughly 100 of these Via Embedded manufactured boards,
and 60 of them (give or take a few) exhibited a rather odd power up
problem.

Symptoms: after the board is powered off for roughly 10 seconds or more,
*and* +5SB is still applied through the ATX connector, (a very common
condition) the power on button connected to the front panel connector
would power up the board, but there are no POST codes to port 80. No #CS
or #OE occurs to the flash BIOS which would signal a code fetch after
reset. In other words, the board is completely and utterly dead. Removing
power completely from the power supply would allow the board to recover,
*or* a power up, power down and then a quick power up would also recover
the CPU board. Additionally, when the board is dead, pressing the reset
button 10 or 20 times would also recover the CPU.

Using a 'scope, I noticed that the "high" signal levels on the two
14.318MHz Oscillators on U19 pins 10 and 12 were of rather marginal
voltage levels, barely making it above 2 volts. (and even then, only for
about 6ns or so...)

The pullup termination is currently 100 ohms to 3.3VDC. Changing the two
resistors to 75 ohms has improved the signal levels and has fixed the
problem on 3 boards that I've tried so far. I just found the fix today
after struggling for several days. Now to repair the rest... The two
resistors are located right next to U19 (a 14 pin chip marked LVC07 and
very close to the DIMM and J13), and the resistors connect to pins 12 and
10 of the chip. The device is an open collector non-inverting buffer
similar to a 7407. The resistors are right next to the chip pins as well.
Doing a little tracing, I believe that one of the oscillators drives the
southbridge, but I was unable to trace the other. Perhaps the northbridge?

Anyways, get out your magnifying glass! If you don't like the idea of
replacing the parts, you could also solder 300 ohm SMD resistors right on
top of the existing ones for a parallel resistance of 75. Good luck!

[Please remove mybrain to reply by email]

Ugh - the problem has resurfaced when the Northbridge is heated up to 40c
or so. The final solution (hopefully)? Install a 2.7K resistor in location
R20. Currently on our boards, the location is not populated. The resistor
is located about 5mm from the onboard speaker. A difficult install as it's
surrounded by the speaker, the PCI connector and a small electrolytic -
but it can be done.

My question now is: Why no response from VIA on their web based forum
http://forums.viaarena.com/messageview.aspx?catid=32&threadid=64314&highlight_key=y&keyword1=EPIA-V+AND+power

At a regular review period, annually or two-yearly I don't remember,
they would divide
the parts stock in 2 , sell off at auction one half and double the
price of the remainder.

Also there are military prices. I was told that when the army wants mil-spec
