I dragged home an Acer 19" LCD monitor a few years ago (found on a busy
downtown street, in front of a grocery store, no other garbage there).

I plugged it in, it worked, at least the Acer logo came on. I connected
to a computer (VGA, the only other connector was DVI), and it worked. So
I moved my other monitor out and put this in place. And when I left
things on, the monitor would seem to reset, certainly the Acer logo
appeared, and nothing I did would get the picture from the computer back.

So I opened it up and changed the obvious power supply electrolytics, none
were bulging.

And it worked fine after that.

Since it worked, and then reset, I would have thought some other issue was
the problem. But apparently not, so where the symptom seems to point to a
solution, it's actually misdirection.

Check the FAQ, try a different cable, try a different source, try a nother
monitor if you've got spares. That might give information that helps find
a solution.

Don't bother poking around the power supply, the problem is definitely on the A main board. Take a close look into all the HDMI connectors and see if there isn't a displaced pin on even one of the inputs. One displaced pin shoved up against another can wreak havoc with the whole group of inputs.

I can't get a schematic up because Panasonic's service website has been down for some time, but older A boards used a separate HDMI select chip, which as you would imagine, would do the selection of the wanted HDMI input and funnel it out to the main IC. These are pretty tightly packed surface mount chips, but are replaceable. We see them fail most often in the summer, when lightning activity whacks these chips. It's possible yours was damaged through one port, and the chip has been limping along and finally failed.

Later Panasonics incorporated the HDMI select into the main chip directly. Since these are ball grid ICs, you're better off replacing the A board.

Before doing anything, you could try reflashing the firmware, although I've never seen this solve the problem on a Panasonic as it has for other brands.

So the TV shows the usual menus, etc. from the BD player, but only
throws an error when you try and play a disc?

Some form of weird copy protection? Tried a known working disc?

Could the TV have had an over-the0-eir software update without yo
knowing, which has broken something?

I figured out how to pronounce a Led Zeppelin song from reading Andy
Capp. D'yer Maker? is pronounced Jamaica (more or less). The song is a
loose reggae.

You were not the OP - although you became directly embroiled in the argument
on his side, William. The OP was someone who I had not seen on here before,
and was asking about replacement batteries for said watch, because the
originals were no longer available, and the recommended replacement made it
run fast for a few days, or something like that. That caused a well known
name this side to throw in a comment about it being a "crap design" as I
recall, making a bit of a mockery of the name "Accutron".

The OP took deep offense at this, and no amount of telling him - or you if I
remember correctly - that the comment had been intended as humour that you
both had failed to understand, would recover the situation. Still, over and
done with, and no point in resurrecting it all again, so we'll just leave it
there, shall we ?

I used to be the keyboard player in a band, and we were once playing a
residency on a US Navy base in Spain. A guy came up to me and asked if I
played by ear, to which I replied "no, I usually use my fingers".

He got most upset, thought I was being nasty and taking the mickey.

That bit of British humour just did not cross the Atlantic at all.

Thank you for clarifying, but I can't leave it there.

When written out, /without/ modification (such as verbal inflection or tone of
voice), "crap design" has only one meaning in American or British English -- a
criticism.

Now, if the person had written "crap design :)" -- there would have been no
argument.

I think the slang terms "Taking the piss" and "He's pissed" are pretty
funny when I think about how they are used where I live. And I've
always wondered about "Bloody". How it became a bad word. And what
happens when someone or something is covered with blood? What do you
say? I like steak rare. I will order it bloody. In a nice restaurant
in London I suppose it woule be a faux pas to order a "bloody steak".
I think I need to look up the etymology of bloody.

"He's pissed" can have two meanings, one of which I'm sure we share, and
that is being a bit mad about something. It's abbreviated from "pissed off".
But here, it also means being drunk, and the process of becoming so is
"getting pissed". But getting pissed can of course also mean becoming a bit
angry ... :-)

"Getting hammered" or "He's hammered" are also phrases for drunkenness here.
It can also refer to being under the influence of drugs.

Bloody is a funny one. I've never looked into its origins as a swear word.
It is very mild though, and is often used in conjunction with another word
as an outburst of exasperation or shock as in "Bloody hell!" or "Bloody
Norah" - and no, I've no idea who 'Norah' was ...

Yes, a person covered in blood can be described as bloody, as can a rag or a
handprint or whatever. It's commonly used in that context.

If you asked for a bloody steak in a decent restaurant, they might look at
you a bit sideways, but would understand what you wanted. In anything less
that a decent one, they would probably just not understand you at all, and
would think that you were swearing. Some restaurants won't even serve a
bloody steak, such is the Health and Safety madness here now. All the same
definitions of steak temperature apply here as well as in the U.S. but the
same temperature is normally a little less here, so if you ordered a 'rare'
steak here, it would normally be a bit pinker than you would be used to if
you asked for it rare your side of the pond. If you ask for it very rare, it
will normally be a little bloody in the middle. If you want a piece of meat
that a vet could bring back to life, you can ask for a 'blue' steak. This
has been really quickly flash cooked, and is only about 2 points to the
right of raw through to the core.

I believe there's also a sexual connotation, in some contexts.

One theory is that it comes from "B'r Lady" or "By our Lady" (a
sacrilegious reference to the Virgin Mary). There are lots of
competing theories... it seems as if nobody really knows for sure.

A college friend of mine used to use the instruction "Show it to a

"Bloody" is a corruption of "by our Lord". It is "bad" because it's considered
disrespectful to use it as a derogatory term.

The Gilbert & Sullivan opera "Ruddigore" was originally titled "Ruddygore".
People actually refused to see it because of the resemblance of "ruddy" to
"bloody". So Gilbert changed the name.

When someone asked Gilbert "How's old 'Bloodygore' coming?", he replied "If I
say I like your ruddy complexion -- which I do -- it does not mean I like your
bloody cheek -- which I don't!"

When I was a lad in the UK, many people commonly chose the word "ruddy" as a
somewhat more polite way of swearing than using the very offensive (at the
time) "bloody".

The items I gave you links to say in stock for next day delivery in the
UK, and nothing about extended range, when I look at it. They are also
available from Farnell if you have something against RS.

If you want to know the curie temperature, that is given by the number
stamped on the back end of the tip. It is also the last digit of the
Weller part number, e.g. for a PTDD7 tip, the number is 7, which means
700F, or 370 deg C. Also, 7 is the right temperature for normal uses. 6
is too cold and 8 is too hot.

If you want to know what the shape looks like, type "PTDD7 Weller" into
google image search and you will get a lot of pictures of it. Likewise
for the other tip styles.

Anyway it sounds like you don't want the answer to your problem to be
simple, so feel free to make your own tips and heater, but don't
complain that you have to. I am certainly able to buy them, and have
them delivered tomorrow free of charge.

Got a 1725a here that needs the vertical IC. It's designation is A5U2 and I THINK the part number is 5061-0024. The manual is a shitty scan, but any other numbers I can get out of it are too off the wall, at least that number googles back to SOMETHING.

The Thing about this is that it is missing. Is it a high failure rate part ? Another question I have is if it fits any better scopes. I assume of course they would be HP, but why would someone take it out unless either it was bad, or they wanted it to use in another unit. If they used it in another unit, what would that be that would warrant effectively scrapping this one ? A higher end scope using the same part ?

OK, I could see in a business setting where it owuld not be feasible to replace the thing even with the same model because of anal regulations, but is that a reasonable assumption ? Also, if they fail that much, maybe I should be leary of a used one. I assume there are no new ones.

According to the print, this thing only has four transistors and a half dozen resitors in it. Think there is a possibility of some sort of retrofit ? Like building the equaivalent out of discrete parts ? Might not be absolutely perfect but the thing is useless now.

Either that or part it out. Are the other parts worth much ?

Here you have a retrofit; it makes me remember the "Back to the future
part III" time machine repair with 1955 components.

Thanks. Having the right part number helps no matter what. I notice both of those numbers are lower than 1725, should I assume then that the 1725 is the best of the "family" ? If that's the case, the mystery remains of why this one got the axe. Of course the thing might have just went bad, it does happen.

WOW ! Now that might just save the day. Thanks. I notice a dot RO in the picture there, does that mean Romania ? I've been told by some from across the pond that alot of parts are very hard to get, it's not like the US. They have had to become more resourceful as a result.

So it pretty much boils down to do this unless I can scare up a jubnker with the IC. This looks highly doable. the only thing now is the selection of the MOSFETs. Voltage, current and frequency response are obvious, the only question is gain.

It's obvious that the 1K resistors set the gain to some extent, but the highest gain possible is not always best in tis type of application. Or is it ? a thousand ohms isn't much, maybe the highest gain within reason would be best. If you want to make a suggestion I am highly suggestable. The main thing I know is to get devices that will work in the linear region. That will probably mean looking at some datasheets because most linear applications I've seen are either audio or video amps and neither of them are going to have the frequaency response for this. At least not necessarily. Also, surely the devices exist, it's just that I haven't seen them in the stuff I've worked on.

I actually thought of a retrofit myself, but I was going to stick more to the original, using bipolar. Of course that was not thiknking outside the box in a way - we only need this to do a certain thing, if FETs work, use them and make it easier. I would guess devices like that were not available when they built that unit, but they are now !
