Fault in TV
 

I have 5 year old 29" ONIDA colour TV. Few day before, it goes
suddenly off. Now when I switch on the TV, the 'Chu Chu' sound is
comming but TV is not starting.

I had check all most all components of power supply. I am not getting
any defactive component.

I want a help. I hope I will get it.

Thanks a lot in advance.
