Unlink or isolate the TSH from the circuit, if the sound persists also unlink the FBT and place a bulb as a substitute load.
In that way, perform stability test and performance of the + B source
Check + B filter capacitors and source filters in both the primary and secondary stages.

Hi. Your report is about.
Commonly when doing that tictic is the TSH or some component related to it that is short and does not allow the TV to walk and make the source do that.
So you know, control the TSH and environment. yoke, diodes and train.
if it is in good condition, place a 200w bulb between the + by pin and the flyback pin. In ST mode you should not turn on it. Measure the voltage of + b.
If you don't turn on the spotlight. From PW see and commented that it makes the focus. Turn on the maximum or dim or not on. Measure the voltage of + b at both ends of the bulb.
always with good light and magnifying glass, general review of welds. I observed the state of components that are not overheated or inflated, such as electrolytic. Measure source and flyback output diodes.
