Re: tv color messed up
There is the chance that the yoke has sliped and a purity adjustment is in order, since you would be dealing with voltages that could kill you if you don't know haw to do this the safest bet would be to take it to the shop

U have all the tools and can u also do basic soldering?Tv might have cold sodering joints on the CRT video board socket that connected video board and the CRT tube together.Must take tv aparts and resolders all the CRT holes sockets of the video board.Also resolders the Yoke wires R,G,B connections to the main board too.Should solved this problems.U can't do this,than u must hire a tv Tech to do the repair,sorry.
all colored tv has built in demagnetizer and activates everytime the tv is power on.but there are instances that discoloration of screen due to magnettic effect cannot be remove by built in demagnitizer.you can buy a separate demagnitizer for tv....to use it you need to switch on the tv .plug in the demagnitizer to ac outlet point the demagnitizer in center of the screen/front press the butoon of the demagnitizer ad move it sideways and circles as if your wiping the colors repeat it untill the color is clear.
Good luck hope this could help you..
your rate is important to me..tnx...
If you can get the tv to display the blue blackground(usually happens when there is no antenna or cable feed to tv) check to see if the whole screen is a solid blue, if it shows discolored areas around the screen then you might have to "demag" the screen. See if you can rent a demad coil from a tv shop and with tv on turn the coil in circular movements all over the front of screen till blue is solid.good luck!
The problem with your unit is that when your tube was replaced, it was not degaussed or demagnitized. The purpose of such is to distribute the color evenly unto the entire television matrix.
You can try to demagnetized it by rotating a magnet around the surface( but not so near) of the picture tube while it is operating.
Also, please check for the degaussing coil around the rear portion of the tube was returned and also check for loose contacts.
Most likely your visitor turned one of the controls located on the back of the TV. There are only two controls they are the right side of the set in the back. The top one is the focus and the bottom one is the SCREEN control. You can carefully rotate clockwise the screen control until the brightness is back to normal. If you go to high with it you will see faint diagonal lines going accross the picture.
I believe what you have is a convergence problem and it is usually caused by two Integrated Circuits going bad which also opens up one or two resistors associated with them. Replacing the Convergence Ic'S - (Ik04 & Ik05) and Resistor Rk62 a 1.8 Ohm .5w. Metal Film type should take care of the problem. As far as costs involved, I would guess about $350-$425 to get repaired. With it only being about 4 years old, it should have that many more years left of good use for you.
