I have two RCA TVs, for years, with Guide Plus. About two weeks ago,
the Guide Plus on the 25" started to act flaky, not showing program
detail.  I went through the "99999" reset deal, etc.  Then we had a
black out for about 2 hours. Battery backups faded away.

Hi. I have a Zen Micro MP3 player that has developed a cold solder
joint around the headphone jack (and possiblly also the USB jack). I
have read in other forums that this cold solder problem is notorious
for this particular player. The warranty is past due. The only

This Sony KV36FS320 will not power up, just 9 flashes of the standby/timer LED,
unless I press the power button while energizing the power relay manually, ie
Q608 base drive for 1 second. Then the set will run and -everything- works
until I turn it off again. All standby supplies ...

Ran a little experiment on the GE microwave oven that has been vexing me per
my postings here a few days ago.  As you may recall this GE oven will
perform flawlessly with its control panel tilted out at about a 45 degree
angle, but shuts off after only a few seconds with the ...

I have the following items. Please bare with me being I have found very
limited info. on these. I am assuming that if you are looking at this post

acquire such material?

I have an old pro502 monitor it has served me well for several years
now, but recently the picture is too narrow about 50%, sometimes it is
ok but then it wobbles and goes narrow ( horizontal )
I opened it up and blew lots of dust away, one capacitor seems far

Good Day,
I accidently wrecked my amplified speakers by reversing the polarity
from the battery.  It is a fairly inexpensive set from radio shack
with a sub woofer and two small "towers" . I still get a very quiet

Norcent Model # LT2722, has a grey raster, with no video, & on screen
display is off horizontal,
& can't be read. Can't change inputs. I'm in eastern Canada. Anyone

I'm hoping someone can help me identify (and thus hopefully find a
replacement for) a plug used inside an aged hi fi loudspeaker.
Specifically, it is the plug that attaches the signal cable to the
chassis of a Tannoy 15" Monitor Gold "dual concentric" driver

We experienced a brownout last week, during which we hurried around
the house and unplugged everything sensitive.
Afterward, everything came back up fine except for a Panasonic PV-
D4744S DVD/VCR combo.  It refuses to turn on.  I opened up the case to

My oldest son (18 and brain dead) somehow put our TV into demo mode.
All of the features and specifications of it constantly scroll from
the top to the bottom of the screen.  I cannot find how to get it out
of this mode.  I have seen dozens of posts about this problem where

I have a 5 years old RCA tv  that required a new picture tube just
after de warranty had expired and the price for the installation of a
new tube was ridiculous. It was a good lemon but it was a lemon.
