This is more of a design question, but there are some pretty sharp people on
this board so I'll post it here.  I am designing a closed loop thermal
control unit that would like to be very accurate (+/- .2 degrees C).  I plan
to use a PID controller with an RTD sensor and a small ...

I had to replace my Ultra VGA 1280 with a TFT the other day when it
didn't start as usual.
I have read some paragraphs on the repair-faq and I can identify that

I had posted earlier about this unit and didn't add that the model is an
SLP-300 which is simply a player and won't record and was used mostly in
schools and institutions (not home use).
Any help getting it to work is appreciated.

Model SD-K700.  I normally push the power (or any other button) to boot this
thing.  Today nothing at all happened.  I finally unplugged it for a few
seconds and everything is now back to normal.  I believe I had a brief power
outage a few days ago...hadn't used it since then.

Before starting, I should mention that I don't have the repair experience of
the other posters on this board.  I've no hope of repairing this problem
myself, but I'd like to get a rough diagnosis and a handle on how expensive
it would be to have fixed.  Please bear with me if I ...

I sometimes record radio shows onto video cassette with my VHS VCR, enjoying
the benefits of being able to record at a pre-programmed time and the long,
continuous recording time that that brings.  I record onto the audio tracks
from a SCART patch cable hooked into the headphones ...

My Epson projector developed a vertical roll. Cannot locate any
vertical hold adjustment and my service manual does not provide any
help. Projector is too old to be worth repair shop costs, but I just
replaced lamp ($200) and would like to get a little more use from it.

Does anyone know of somewhere online where I can learn about repairing

I'm trying to remove the E1 board (y/c jungle)
from the main chassis of Sony kv-27xbr35.
It's a vertical board, soldered to connector,
and the connector soldered to the main A board.

I actually asked about this set quite some time back, but unfortunately have
lost me notes on the thread........
The set is a Mitsubishi CS-3515R (manufactured Oct 1992).  When first turned
on, the picture is collapsed into a horizontal line midway between the top

I have a Fujitsu Ten modular radio (Model AE-3050TY1A, S/N 9102692) in my
1985 Mazda 626 and the tuner has developed a problem.  It would occasionally
lose its presets, as in clearing its memory.  My first thought was that the
constant +12 supply line was dropping, but I caught the ...

Hi;
The old company I work for has the (I believe) non-paying portion of
mitsubishi's website. This is of course limited, and non-ASC, but has a useful
feature or two, one of which is a part search.

I am attempting to find a replacement UHP bulb for a friend's Projectavision
DLP projector Model # 97000 DHT 1.  The part number on the bulb is TI
