lamp and temp lights are both off.  I've checked it over for obvious

Here is a strange one.  The only similar issue I can find is the
"afterglow" effect mentioned on older RCA televisions.  Anyway, I have
a Panasonic 28" TV.  It is quite a few years old.  Sometimes (50%+),
after turning it off, the video image still appears on the screen (in

I did some research and don't see where this chassis had the tuner
solder problems as others. The set was intermittent on powering up and
now won't power up. A previous post on this particular set was

Hi. Here is a fix for you if you haven't seen it before. I know the pros
have so this might help some of the smaller shops that don't get these big

It hasn't gone kablooie yet, but the fan in my Toshiba Satellite
A15-S129 has started making a buzzing noise.  Before it goes, I'd like
to know, can I buy this part, and how hard is it to replace?

Hello Group,
    I previously posted a question about opening an ES8092 so as
to replace the batteries. The only reply I got stated that this is not
possible without breaking the sideburns trimmer. My question this time

Dual-trace) can't focus the spot any smaller than about a millimetre
in diameter, & that is at the the extreme anti-clockwise setting of
the front panel focus control. Turning the control clockwise can

Where is the defrost timer on a Hotpoint FF08P frost free fridge
freezer? I've looked everywhere but cant find it.
There is a 'Hotpoint Defrost stat & Fuse N1548' with 4 wires, but
presumably that ends the defrost cycle rather than initiates it, since

Can someone help me ?
Thanks in advance, Marco.
