I have a Samsung TXN 2020 and it seems to be not degausing.  All the
colors are mixed up.  Is this something that requires a circuit board
replacement?
 Ckt board is 2020M4A    --- TXN 2020 X/XAA

My old SONY Video 8 CCD-TR75E seems to be at the end of its life, after all, it gave me 15 years of wonderful movies and colors!
However, if possible, I'd like to repair it, purely because I am nostalgic!
The problem
If I switch the camcorder on, I see the monitor this way:

I have a Canon Palm Printer P1-D printing calculator.  It works fine
using just the LCD, but when I switch on the printing function, it

Hi, I have a Sanyo POA-SP-SU31 smoke housing for my video projector that i

So I bought the replacement motherboard from eBay, and all seemed well with
the machine running for around 10 minutes.
I closed the machine and left it to recharge its battery. When I came to

I'm attempting to fix an old Zenith model SG2795BG. This has an intermittent
teletext type problem. Almost looks like the teletext pops up or flashes on
the screen about anytime. (and yes the teletext feature is turned off)
It's been several years since I've worked on any of these ...

Like the subject says plug it in and push the power button and i
tries to start about 4 times and then quits
I have replaced the following

   I have been told that a data cd (also audio cd) is
first "read" from the middle track. Another person told me

it was first read from the outside (near the edge) track.

I have a battery tester meter (Mallory) that came from a retail store. The
meter is magnetized and now sits center scale, instead of over to the left.
Any solutions to return it to it's normal state.  I tried reverse polarity-
it goes to the left, but then returns to center.

Need some help on a Panasonic sa-pm19 shelf system.  I don't have a
schematic and a google search came back empty.  
What it is doing is when power button is pushed the power board relay
clicks,  waits about 2 seconds then clicks again.  No display or any

When turning it on the set just clicks and the red power indicator light
starts blinking twice every 1 or 2 seconds.  No picture or just a flash of a
black and white one.  I found that if I unplug the power and wait a few
hours, the set will come on normally.  Before I take it ...

I have a Sansui R-7 receiver which works fine except that when the power is
turned off there is usually a fairly loud click from the speakers.  Does not
seem to be loud enough to harm the speakers, but certainly annoying, and not
at all what I would consider normal.

Last night by accident I unplugged the Sony Vega KV36FV15 which wa
turned off, when I plugged the TV back in, the TV came on, without th
power button being pushed!!  Once the TV was on there was no picture!!
After trying everything to get a picture,  I discovered that the PI

This set is a 4:3 HDTV set 27".
It has been working perfectly for about a year though the HDTV picture
