Removing a CRT television from its case?
Blanka:
Why not remove the 6 inch malformed colouring? Just find a TV repairman who can degauss and clear up the magnetic field of the TV.
BTW, what is illegal about decasing your TV? If that is ilegal in the US, the law is really sick.
AndyWarne:
There really is so much scaremongering nonsense talked about TVs and monitors.
There is no danger at all actually removing the case, provided it has been completely disconnected from the mains for 30 mins or more, if it was a working TV.
Once the case has been removed, and the TV is powered up thats a different matter altogether of course.
I have posted many times about this but again:
All modern TVs discharge the CRT by themselves but putting that aside for a minute... even if it were not discharged, this is like saying a car mechanic must drain the fuel tank before he opens the hood.
On a non-discharging CRT (such as older arcade monitors) the charge is completely enclosed in the CRT and touching no part of the monitor will expose you to the CRT charge except digging under the final anode cap (the rubber cap) which is like a fuel cap on a car.
Having said that, there are other charges on the power supply caps in monitors which can retain charge especially if the monitor has a fault, and these are not discharged even if you do (incorrectly) discharge the CRT. These drain quickly on a working monitor though, when powered off.

It is a pretty old set, so I assumed it would cost more to repair than it is worth. Perhaps that is something worth looking into. I really know nothing about the process.

I was wondering the same thing.
G1zm0:
i decased a flatscreen 22" philips to fit in a standard woody cab where the old 21" monitor used to be,
i took all casing off but kept the bottom part where the pcb sits.
mounted it on to the "modified" board that used to hold the old monitor, i used 4 bolts with nuts to affix this to the board after cutting it to fit.
then mounted the plastic part to the back of board so pcb could sit on, and it went in like a dream.
the tv had been unpowerd though for 2 weeks.

1st. lets try a simple fix.
do you have a large drill? or a blender?
( the bigger the electrick motor the better)
have TV on. (powered up) lets say blender form now on. (any high speed motor will do) (hair dryer is not that good)
start in upper left corner. in a circular motion ( I mean as close to screen as you can get) go clock wise corkscrewing to center of screen,
once you get to the center , pull electrick motor away.( hold motor and take 3 steps back)
this should fix it.
If this don't I will answer your question
open TV box from the back. ( TV UNPLUGED!!!)
do you see a red suction cup?
get a large screw driver. some thick wire. strip wire to tape copper wire to screw driver.
strip other end and attach to metal frame of TV Tube.
lift up red suction cup. (see 2 wires under it?) touch screwdriver to the 2 wires under suction cup.
There should be a loud "POP"
now it is safe to handel.
