usually capacitors are the problem on the TDA03211c power supply. 450v (volts) @ 10uf. change both. beside inverter filters.

First, check the power supply module to make sure it does not have any bad caps with bulging/leaking tops whcih is very common problem for 2~3years old TV.
You will also have to mkae sure all the DC outputs are good. Bad DC can cause a lot of starnge problems.

Possible that the main power supply unit which is the SMPS- switch mode power supply- has a faulty capacitor or in the INVERTOR board which has changed the value and so the frequency being changed can cause higher huming level- reduced to lower frequency.
so check the board for leaks , if so replace. Also check if the threshold voltages are below level in these circuits. if so the capacitor can be identified. If there is change after the component heats then simulate the circuit board and confirm using a hair dryer.
