Imoudu: I used a low melt solder and used one soldering iron to de solder the ic. one pin at the time. have a good day.

Babu:
thanks man. usually humming sound is caused by bad capacitors mainly in the power supply area. check these capacitors for bad ESR reading

Albert: they fail very often like you said, there is no cooling in these devices. I have repaired these before but this was the first one that had ticking noise in it, the rest was just so sound output. have a blessed day

Still odd that these small smd 10 Watt D-class amplifier chips do not get any cooling. The thicking noise is likely caused by the amplifier chip that probably gets to hot and fails to amplify within its limits.
