Did you get your set fixed or did you replace it? My same set did the same thing. Turned it off for 2-3hrs after watching it and when I tried to power it up- nothing but the sound it would normally make just before the major power up, sort of a relay click sound. No picture or sound but the red light blinks non-stop.
Pull the back Off Disconnect CRT board connected at End of picture tube then turn set on and see if it comes on with volume, high voltage you can feel front of tv for static elect.... Let me know what happens then i can tell you what is wrong with TV.
Its magnetic effect on picture tube. Power Off TV for 20-30 minutes then turn it On, hope problem will be resolved. Please also check and remove any speaker or some thing have magnet near by TV. If color spots are still there, picture tube need to degaussed / demagnetized.
There are some components that have become thermo sensitive from age and use. After the defective parts come up to their operating temperature they go out of specs.
Most of the time this type of problem comes from the power supply. Sometimes it is from another board that is causing the shut down.
The fix is to start by replacing the power supply for a start. If there are still any faults, the tech will try the boards to zero in on the defective one. Once he locates the defective board, if it is not worth to service, he will leave the new board in the set.
This type of repair can be in the average range between $200 to the $500 range depending on the exact fault. This is providing that the fault is not inside of the screen itself.
