Question about Televison & Video
Just started making chirping sound,no picture, no problems before this
Problem most likely on middle board----High voltage deflection board--the chirp is a primitive indicator of shutdown or self defense in these sets.

A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps
