There may be several reasons for the appearance of colored spots. All of them are associated with various factors and require different solutions to the problem.

Possible factors:

• the most common reason is the demagnetization of the standard kinescope system;
• interruptions of cyclic switching on and off the unit;
• additional household appliances that create a strong electromagnetic field (in case the equipment is near the TV).
