Yup.

or is GG's web interface not capable of x-posting?

It seems you have missed my posts on this: (Got me plonked?)http://groups.google.com/groups/search?q=selfish+inefficient+jeffm_&s...

Google allows up to 5 groups on the To: line.
Note: sci.electronics.repair,alt.engineering.electrical
were removed from the cross-post because of this limit.
(I'm posting from Google.)

I'd look for myself, but I abhor GG and get hives when I go near it.

I find it usable once you get used to its quirks.
The big problem is in Google not requiring newbies
to click thru a checklist of DOs and DON'Ts
before granting them initial access.http://66.102.9.104/search?q=cache:Gnnj10AfkBUJ:bibleocean.com/OmniDe...

My main beef with GG is no killfile or "ignore this user" feature.

No, you need an exact replacement inverter, specific not so much to the
LCD panel as to the monitor or laptop into which the panel is being
installed.

Agreed. I've rarely worked on those but they are made on custom boards to
fit VERY exacting and confined spaces. Trying to bypass going direct to the
maker's supplies will cost more (in time, effort, plus cash) than paying
what they ask. So much so that this might be why they charge so much. They
know damn well they can get that money. And they might not cost that much
anyway, they can't fleece a repair person quite as closely and ruthlessly
as they can fleece a member of the public who doesn't know that a Ł90 PSU
is really worth Ł30 or less.

Look at the firm's product line though. To save money they might use the
same custom board in many machines. You might find a low-end version cheap,
and save money if you don't want a regular supply of bits. Still worth just
paying up front though, unless you've got the time and attention of a
repairer of laptops and such.

The problem here is that there are six dead LCDs on my hand, and they
are all from different manufacturers. If all of them are of the same
make and same model, then it's okay, I can place an order for six
pieces of the exact part. In my case, I may have to place six
different orders for ONE piece each. Troublesome aside, the cost does
add up !

Hi ! Gaetan,

We do have the stock of the NJM4565 !

Are you interested ?

Thanks !

Hi

Is there a direct (but much better) replacement ic, with very much lower
distortion, to replace the NJM4565 (with same pinout) ?

Thank

I need replacement number for those transistors;

pnp TO-5 70V 5W @ Tc = 25C 100MHz
Choose your own substitute.

40409

npn TO-5 with attached heatsink 90V 3W 100MHz

40410

As above but pnp.

There are no direct replacements for the above. A popular substitution back in
the day was the 2N3440 and 2N5415 with a good heatsink.

BFW90

That's a job for google.

and larger version at

and schematic I drew based on it:
http://personalpages.tds.net/~wilykat/schem.png (transformer coil
diagram unknown but it's drawn by the pin number)

Transformer has no marking other than high voltage. I am not able to
figure out the wiring diagram of the transformer without de-soldering
and removing it. 2 transistors are D1616, resistors are aprox 1/16w
SMD. Inductor has no marking either but it appears to have iron core.
Capacitor on the primary side has marking 1J100, and one on secondary
side has marking 22 and 3KV

Any idea what is the supply voltage? I think the typical inverter
voltage of 12v is too much as the board looks like it may be from a
small flash light type device.

TIA

I'd start off with say one cell, or 1.5volts and work my way up until the
lamp is stable and then make sure nothing gets too hot. Then the choice is
up to you.

My meter only goes to 3kv AC and it was off the scale by the time I
got to 4v DC. But I got a nice steady light at 5v to 6v so I guess it
was designed for 4 cell flashlight. After I let it run for about 10
minutes, it was shut off nothing felt warm.

Nothing like a careful bit of testing to come up with an acceptable answer.
If you're happy with the light output, I think you've solved your problem.

In a similar vein. If an amp needs a rare or expensive or unattainable

with
a strip of matrix board on the new block pins then insulated wires
crossing
over one another to the original pad positions.
It is usually possible to work out the DC rails, i/ps,o/p, comp, mute
lines
even if a pinout for the original is not available.

I do miss those Maplin 150 watt mosfet modules, great for resurrecting
old stuff like H-H PA amps and the like. There`s nothing quite like them
now, I must have built over a hundred, and most of them I bet are still
working.

Assuming you put in spring clamps, or such, then cutting off the protruding
tab of the TDA7294 leaves a block only 20x10x4 mm , so 2 easily go in the
space of an STK... etc and those are usually quite a bit less than 2x 100W.
I wonder if they're bridgable, I'll have to dig out the pdf.

0.4W zener but what voltage?

I can't help, but FWIW, the Internet has references to "QSCH" devices
made by HP.

HP also has a lot of diode parts of the type HSCH-xxxx or HSCHxxxx.

The "SCH" in the part number seems to suggest a Schottky diode.
