I wonder what the cat thinks? I guess it's VERY careful where IT pees now!

I recollect hearing of a gang of boys whose initiation ceremony consisted of

Connect the Red and Black to the cylinder at the lower end of the Picture.
There are 2 solder pads towards the top of it, and 2 solder pads towards the
bottom.
Solder the red and black to the bottom 2 pads (Polarity doesn't matter
unless you use 2 or more mics)

Thanks you two... I'll be carefull and se if i can find the

To be perfectly honest, sitting overnight is ample time to discharge 99.999% of
caps or CRTs. I'd say 4 years you're relatively safe.

Ryan:
Which P810 do you have ? There are about 4 or 5 different ones.
I have a schematic on the one using the HV8SA main board.
I think there is a "1M" after the full model number (starts with a VC).
You did not put any of the capacitors in backward, did you ?
John
 
Did you ever try to remove the anode cap from a CRT on a set that has been
sitting for a week, and you didn't discharge it? There are some models that
are designed to slowly discharge on their own, but not all of them. If not,
try it, and let me know how you feel after!

Interesting, I can say I've been in the business for 27 yrs and have never once
been shocked off a tube that has sat overnight, regardless of whether it has a
bleeder resistor in the design or not. I've been mighty lucky all these years I
guess :)

Wouldn't a rubber seal exacerbate leakage issues? I mean, wouldn't it
effectively *create* a gap through which microwaves could leak?

yes typically these are standard incandescent lamps, what a bummer, if they
had been leds you would not probably be changing them, they are 12volt
mini lamps avail at radio shack, get some, desolder the dead one, solder
the new one in its place, and get the color cap off the old bulb and put
it on the new one. good as new or at least for a few more years! id change
the good one also chances are you will put it all back together and 2 days
later it will be dead
 
if the transformer is open its likely that somewhere in the winding of it
the wire is just burned out. to check a diode u need a multimeter that
will do resistance checks, check resistance over the diode, one way (the
right way) should be close to 0 ohms, the opposite way, should be very
high (kiloohms,megaohms) if they are close to the same or both really
high, it is bad. i dont know how well he checked it, transformers usually
last a good while, to check it, just make sure its putting out the correct
current right at the transformer. typically i usually find if the trans
is burned out you can see it and may be able to smell it also. if trans
good, look to the voltage regulator ic or transistor (assumeing it has
one) one leg should have an input voltage from the transformer, another
leg will have a much lower voltage that controls the load. the last leg
should have the output voltage (for a 3 leg transistor). measure all of
these to the ground and determin where you are loosing current
 
you may have done something that is triggering xray protection, other than
that i wouldnt know why it would not turn on only when the neck is
connected. im not sure but i think if the guns in the tube are over
energized or a spark is arcing somewhere the xray circut will power some
or all of the functions down to prevent excessive radiaton.

It should be easy to find a suitable transformer, just make sure it's also
class 2, which means if something shorts it will fail gracefully rather than
catch fire, most these days are.
 
It seems the black spikes happen only when there are areas of the
screen which contrast - if it's one uniform colour, or range of
colours, no problem. Contrasty scenes cause issues. I'm actually using
the display to post now, but it's painful on the eyes!

Maybe "metalized" silicon rubber is a good shield for microwaves?

They should not be affected but equally I see no reason they wouldn't pass

From Plessey (try and see if it's on a obselete chip archive at Zarlink).
1982 IC Master describes it as "Latch, Quad with non-volatile Memory".

Some sort of logic combined with EEPROM, judging from the mention
of a "Nonvolatile Logic Applications" handbook, in the 1986 IC Master.

Sony Beta format was immune to Macrovision,IIRC.
