You just hijacking and the TS already leave for over 2 years and 4 months, maybe he can't give you the answer, so move the posted here.

In the start of the problem, the video came for few seconds and then gone.

I replaced the capacitors as shown. But no effect (No video but only sound).

I also tested and replaced the FETs (KF 5N50).

There is dim blue light on the screen. Sound OK Channels are Tuned, But No Video
