I have a Denon Radio/CD player that has been dropped, pushing the power
outlet connector in.  The section of pcb that branches off to the power

A lot of these cute little phones (mine included) seem to suffer from
progressive key failures on the joystick mini-keypad.
Determined to fix the wretched thing, and after acquiring the
necessary Torx t4/t6 screwdrivers and the wonderful detailed

I almost can't believe it, but after 35 years, I still get confused
about positive and negative.  Sorry to bother you, but I just can't
remember.
I'm replacing a bridge rectifier with 4 separate diodes, and I know

Heat element burnt out near the terminal so I rerouted and crimped it back
on and bypassed the blown thermal fuse with a 1/2" length of 18 gauge solid
copper soldered to the remains of the fuse leads. There is a bimetal thermal

I'm trying to repair a Ferguson TX100 chassis T.V.  I have looked a
various T.V repair help sites but cannot determine what the fault is?

I have a RCA PTK169PGA RPTV that I have been working on and it has been a
real dog.  I can finally get the TV to come on, the audio is fine, but I do
not have full deflection in either the vertical or horizontal direction and
the convergence is way off.  I have found that at ...

Of all the brands of LCD computer monitors I have looked
at locally, none of them display equal brightness from top
to bottom without tilting them forward and/or looking down
from several inches above the upper border.

Is S-video the same as regular video and left and right audio (such as
feeds a tv monitor, via RCA plugs), but just combined so it all fits
in one connector?   Or is it electrically different from that?
There are several reasons I would benefit from understanding this.

I have a Sony TC-FX220 stereo cassette deck that has a problem with
distortion of the higher frequencies, "flutter".  Has anyone dealt with this
problem on this machine?  Would it be something mechanical?
Thanks.

I have a Brother HL-2060 Laserjet printer for which I replaced the
fuser.  Does anyone out there know the service code sequence to reset
the fuser error display.  I haven't found much luck out there

I am in Southern NH, zone 5b and am considering giving a fig tree a
