What to do if the monitor flickers?

Question

JavaScript

After turning on the monitor screen blinks for about 15 minutes, and then starts to work normally. What could be the problem? Maybe capacitors?
Thanks in advance

Answer 1

1. eval
   
2. recursive descent
   
3. refuse expressions, and imitate a real pocket calculator - when you click on addition / multiplication / ..., the current number is remembered, the selected operation is remembered, the input field is cleared (or, if there is already a previously memorized number and operation, the corresponding calculation is performed and the result is displayed)
   

Answer 2

Yes, with a high degree of probability, electrolytes are swollen.
