Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

It sounds to me like one of your color tubes went. If I had to guess I would say the red tube is shot. Its cheaper to buy a new tv almost. You can get a quote over the phone and compare the cost of repair to the cost of the tv.

Most likely a unit this age with start showing signs of weak crts. These crt's hava a life of 7 to 10 years and your discription is failing crts. I am afraid it is time to move to a new unit.

IS the screen white retrace lines ? Have you looked into the CRT lenses while they are on with a signal applied through the input to see if an image is displayed in the lens lens of the crt? Let me know what the answer is to these two questions and we will go to the next level.
