No picture but has sound


The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up.
The TV must be taken apart and tested before eventually replacing sustain boards.

Delay to see the picture


Your power supply is going south, I have an old sony with the same problem. The voltage level drops and does not have enough 'kick' to start. It will work better when it is warm. The module will need to be replaced.
