I don't understand this one.
the video implies that the power supply "pushes"
the current rather than allowing the device to draw it.

I agree with you - this is a wierd suggestion by PC World.
But, I can tell you watched the video because that's exactly what it says.

PC World seems to imply that a larger capacity power supply INITIAL
current/voltage (they call it wattage) surge into the reluctant disk drive
could JOLT the dead disk drive into cooperating - sort of like a Taser for
reticent hard disks.

Wattage, as everybody here seems to agree, is the actual power consumed
by a device; the wattage rating on a power supply is the highest power
it's capable of or designed to supply. Amperage is only drawn to the
level required by a device; if a device is not defective it will only
draw up to its rated amperage and the supply has to be able to meet that
demand. Voltage higher than the designed operating voltage of a device
may damage or ruin the device. ISTM PC World must be outsourcing its
technical writers these days.
Yes. To people that do not have a clue.

Just a clumsy description.

I think I get what Rod Speed is saying.
When I start my blender, the lights dim for a second in my California
kitchen. Then everything is fine.

I think what Rod Speed is saying is, if the hard disk drive motor is
drawing too much current for the original power supply to handle, then
adding a larger capacity (more current) power supply, will allow it to draw
more current than the original power supply could handle.

That, in an emergency situation such as mine, might be the way to free a
"stuck" drive.
No. While the idea is sound, the numbers and other facts are not.
One problem is that PSUs (unless dying ones) supply far, far more
power than a HDD needs to start.

As noted, my drive isn't stuck - it's just clicking and spinning until the
clicking gives up ... so I think I'll give up on the larger power supply.
Plus, I'm using the Vantec IDE-to-USB adapter which comes with its own
power supply.
Thet is the next problem. Historically HDDs used to have heads stick
to surfaces. With better coating this has not been an issue for a
decade or two.

Funny thing, the hard drives I tested STILL WORK on the Vantec IDE-to-USB
adapter even without plugging in the external power supply. I guess they
get power from the USB - but I'll use the external power supply also to
power the naked laptop hard disk drive.
Standard, although it overloads the USB port on drive startup.
Typically not a problem.

The good thing is we're learning - the bad thing is that we probably
can't use any freeware on earth to resurrect this drive ... or can
we?
I don't think you can. From a certain point one, hardware defects
cannot be corrected or worked around with software anymore.

I was wondering why BOTH the hot water outlet and the cold-water inlet had

If you are talking about the galvanized nipples with blue plastic flaps that go
between the heater at the cold/hot ports, those are thermal breaks - not check
valves. They reduce the heat loss from the tank into the pipes when the water is
not being used.

A check valve is significantly larger than a nipple and would typically only be
be found after the main valve and before the heater.

The CRT is failing. The AKB circuit blanks the screen if the
emission is below a certain point. You may be able to get a
little more life out of it by increasing the G2 voltage a
bit.

----------------------------------

SOCIAL SECURITY:

(This is worth reading. It is short and to the point.)
Perhaps we are asking the wrong questions during election years.

Our Senators and Congresswomen do not pay into Social Security and, of
course, they do not collect from it.

You see, Social Security benefits were not suitable for persons of their
rare elevation in society. They felt they should have a special plan for
themselves.

So, many years ago they voted in their own benefit plan.

In more recent years, no congressperson has felt the need to change it.
After all, it is a great plan.

For all practical purposes their plan works like this:

When they retire, they continue to draw the same pay until they die.
Except it may increase from time to time for cost of living
adjustments..

For exa mple, Senator Byrd and Congressman White and their wives may
expect to draw $7,800,000.00 (that's Seven Million, Eight-Hundred
Thousand Dollars),
with their wives drawing $275, 000.00 during the last years of their
lives.

This is calculated on an average life span for each of those two
Dignitaries.

Younger Dignitaries who retire at an early age, will receive much more
during the rest of their lives.

Their cost for this excellent plan is $0.00. N ADA..! ZILCH...

This little perk they voted for themselves is free to them. You and I
pick up the tab for this plan. The funds for this fine retirement plan
come
directly from the General Funds;

"OUR TAX DOLLARS AT WORK "!

From our own Social Security Plan, which you and I pay (or have paid)
into, every payday until we retire (which amount is matched by our
employer). We
can expect to get an average of $1,000 per month after retirement.

Or, in other words, we would have to collect our average of $1,000
monthly benefits for 68 years and one (1) month to equal Senator Bill
Brad ley's
benefits!

Social Security could be very good if only one small change were made.

That change would be to:

Jerk the Golden Fleece Retirement Plan from under the Senators and
Congressmen. Put them into the Social Security plan with the rest of us

Then sit back.....

And see how fast they would fix it.

If enough people receive this, maybe a seed of awareness will be planted
and maybe good changes will evolve.

That's certainly possible, but before condemning the CRT it's worth making
sure that's the problem. When I've seen this happen, the picture will flash
for a while and then finally come on, if it didn't do the flashing thing,
suspect something else.
 
It does flash on and off before it finally comes on. What have you

Just what the other guy said, weak CRT causing the AKB circuit to blank the
picture.
 
I found the G2 on the board attached to the CRT. When I dial it up the
flickering begins sooner than before. It certainly isn't acceptable. I
saw a post from 1999 from a David which may have been you.

"Here is a bit of information regarding the video blanking at turn on
in Sony tv
sets that use the IK detect line.

With the tv set in a full cold start, look at the cathodes of all
three of the
guns with the oscilloscope. It will take some work with the scope
settings to see
the blanking pulses during the vertical retrace time.

Take a good look at the pulses, they all 3 should be fairly close to
the same P-P
value, usually between 50 and 150 volts. If one of them is much
smaller or much
larger than the other 2 the crt guns are getting very weak and way out
of balance
causing the blanking problem at turn on. At this point the only
proper fix is to
replace the picture tube.

In about 50% of the cases a newer low current crt rejuve only on the
bad gun can
sometimes rebalance the guns for better AKB performance.
In some other cases a slight increase in the g2 voltage will allow a
better turn
on and gray scale.

We have seen a lot of older Sony tv sets coming in with the same
symptom as he
described it with the above troubleshooting and failure result.

Some older sets also had bad solder connections to all of the voltage
regulators
in the center of the main circuit board.

The ones with the stand up power supply on the side of the chassis
have a special
capacitor 1000uf16v that goes bad and can cause poor power supply
regulation.

David".

I hate to toss out what was a very nice set. Do you have any thought
that the power supply board could be at fault? I could certainly
replace the capacitor mentioned above if it would do any good. I
apologize, I'm still in denial.

Barry

You could measure the output of the power supply, but the tube is almost
certainly shot. Perhaps you could find a lightning damaged or otherwise
defective set with a good tube? If you're in the Seattle area I have a dead
27" Sony console with a good tube you can have but shipping is not
practical.

how old it this tv?
-B
 
From our experience, most of the time this is caused by the CRT going
weak. It is possible to have a power supply fault that can cause this
type of symptom, but that is very rare. When the CRT is very week, the
AKG circuits keep it biased off. In the case that the CRT is taking
very long to warm up to have enough emission, the AKG circuits will
keep it biased off until the emission is high enough.

At this point, I would be looking for a new TV set.

times in the past. Would like to revive it one more time. Your help is
appreciated!!!

Thanks!

How can it be that replacing a drain valve in a full tank leaks not water?

I still feel badly that I didn't replace the plastic drain valve with the
brass ball valve because I was afraid the plastic was not removable (that's
what Sears salespeople said anyway, instilling FUD in my mind).

I was subsequently reading how to replace the plastic drain valve after the
fact and they all seem to say it won't leak if I do so with a full tank.

Huh?

How can removing the drain valve at the bottom of a full water heater not
leak 50 gallons of water?

I already saw, first hand, what happens when that drain valve

Maintenance Tip #21 Drain valves
Drain valves usually come when you buy them from a manufacturer. �They used
to be brass. �You should install a 3/4 ball valve on your water heater.
The plastic ones are prone to leaking. �To install a brass ball valve, turn
the gas or electricity off and open a hot tap inside the house. �If you
have a cone-shaped valve, unscrew it counterclockwise six turns or so and
pull it out at the same time. �Now turn it clockwise while continuing to
pull and it will come out. �Wrap Teflon on the nipple that is exposed on
the water heater. �Attach the ball valve now. �If you have a plastic drain
valve that looks like a hose bib, unscrew it by turning the entire valve
itself.
A little water may come out while you're installing a new valve, but not
much at all. �Wear gloves to avoid getting scalded.

Their idea of "a little" water is "about 5-10 gallons." �I would drain
the tank prior to replacing. �I did just this on two heaters in my
basement last year and I was unable to completely drain them (the WH
drains are lower than any drain in the house) I had a mess to clean up
after each one, and lots of sediment came spewing out too. �It was
especially fun as both were so close to the floor (wh's not on stands)
that I had to leave the new valves open while starting the threads.
Assembling the whole mess on the bench and installing the garden hose
cap is highly recommended.

There will be less water coming out than you experienced with your old
tank because of the vacuum of having all the valves in the house shut,
but it'll still come out eventually.

leave all the faucets OFF while changing valves.

the plastic valves are fine if they get just ONE use, to drain the
tank at end of use.......

Also, before draining the tank to remove sediment or to work on it,
it's a good idea to shut the gas off a long time before you're going
to do the work. That way, you can use up most of the hot water in
the tank through normal use, instead of wasting it.

I found the G2 on the board attached to the CRT. When I
dial it up the
flickering begins sooner than before. It certainly isn't
acceptable. I
saw a post from 1999 from a David which may have been you.

I hate to toss out what was a very nice set. Do you have
any thought
that the power supply board could be at fault? I could
certainly
replace the capacitor mentioned above if it would do any
good. I
apologize, I'm still in denial.

Thanks David! Is that an adjustment on the flyback?

The CRT is failing. The AKB circuit blanks the screen if
the
emission is below a certain point. You may be able to
get
a
little more life out of it by increasing the G2 voltage
a
bit.

David

Usually, yes (the lower one). Some Sony sets had the G2
adjustment on the CRT socket board. I do not recall which
one was on this model.

David
Hello Berry,

I did not write the archived post, but it appears largely
accurate.

I assume you do not have a schematic of this set, but there
is one more thing you can try. You may have low heater
voltage on the CRT, but first you have to determine how the
CRT filament voltage is supplied. A simple voltmeter can not
be used to measure the filament voltage. These sets get that
voltage from a winding on the horizontal output transformer.
There are two cases: 1) the winding directly feeds the high
frequency AC to the filament [usually through a low
resistance voltage dropping resistor of 2 - 5 ohms], or 2)
the voltage is rectified and filtered with a capacitor and
DC is fed to the filament [again possibly through a dropping
resistor]. If yours is AC fed, Bridge the dropping resistor
with one of equal value and see if that helps. If so, you
can leave the resistor bridged and coax a bit more life out
of the set. If it is DC fed, check the filter capacitor for
high ESR or just replace it. If that helps your are done, if
not, try bridging the dropping resistor as above.

David
 
Thanks all!!!! I'm convinced.

From our experience, most of the time this is caused by the CRT going
weak. It is possible to have a power supply fault that can cause this
type of symptom, but that is very rare. When the CRT is very week, the
AKG circuits keep it biased off. In the case that the CRT is taking
very long to warm up to have enough emission, the AKG circuits will
keep it biased off until the emission is high enough.

At this point, I would be looking for a new TV set.
