My old 27"Zenith TV finally gave up.I smelled burnt insulation.
Reading the TV ads put me in a quandry.The technology is in
transition.So I went down to the Goodwill auction and bought
a used 27" RCA TV for $10.
 
  Usually these electronics have some defects that I often can work
around.Opening it up,I found very little dust.Everything looked good
except the color.All white images had a yellow tint no matter how
I adjusted the COLOR,TINT,CONTRAST,GREEN-RED mix.I tried the default
setup.All no help.Using the default setup,the faces of people had a 
bluish tint.In the back,I could see some screwdriver color 
adjustments but these had no effect.I could see controls for 
SCREEN and FOCUS but I didn't have the required  small diameter tool 
with a hex head .So I carefully drilled a lot of 1/8",then 1/4" holes 
around the hole marked SCREEN and cut out the plastic.Then I used a 
9/64 " hex bit to rock the high wattage pot and saw no change.
 
The board on the socket of the TV tube didn't have the red,green and 
blue pots that I was familiar with.
  Now,I beginning to think that the magnet adjustments on the 
neck of the TV tube may need tweaking.There are 3 sets and I was
waondering which one I should start with.I would watch to make white 
images less yellow.    Any suggestions?
