makes a repeated clicking sound as if the mechanism can't move & then gives
up. I opened it up (past the point of no return even though I don't know what
the hell I'm doing; I usually could just ...

The problem is a constant pincushion effect that is concave at left and
right sides of the screen. I have the schematics for this model. Any ideas
on what might be causing this? A bad cap? I'll try some freeze spray on  a
few areas.

My college aged son's 16-month old 20GB IPod (2nd generation I believe) died
a few days ago.  The LCD display  is still working and the battery seems
fine as well.  When the USB cable is plugged into to computer, it ...

a stepper motor is microstepped. when pulsed, the shaft moves by a
small step and then returns to its original position, ultimately

I'm quite new to arcades but not to electronics.  I had some problems with
two monitors and now I want to understand what's going on !

Out of curiosity, who among you own and/or use both a Sencore Z-meter
(pre-LC103) and one of the portable, dedicated ESR testers?  How does the

We have a Hitachi Ultravision Model 50UX26B projection TV that was
made in July 1996.  Lately it has been shutting itself off at random
times.  Hitting the power button on the remote usually turns it back
on again (you actually need to hit the power button twice; the first

I have a 9/16" threaded shaft which screws into a socket.  The threaded
shaft seems to be plated with chrome or nickel.  The socket seems to be a
stainless or aluminum alloy of some sort.  The threaded shaft has "set" in
the socket, and doesn't want to unscrew.  As of yet, I ...

I have a Sanyo 31" TV that is dead with a blown fuse.  I replaced the
fuse and now it turns on, I hear the whine of the flyback, and then it
turns itself back off.  There is no schematic inside the case either.  I
think it may be the flyback and the HOT along with a power resistor ...
