Computer And LCD TV Repairing

This Panasonic CRT TV came to repair with the complaint of no sound. normally no sound fault are often because of bad speaker, broken speaker wire connection, Mute, corrupted EEprom data, missing dc supply to sound output IC, bad sound output IC and etc.
Once the TV cover was removed, I checked on the speakers first and located both of the speakers were good (have Ohms reading).

then, I checked on the DC supply to the sound output IC
On the DC supply side to the sound output IC, I measured and got 21.2 VDC but on the opposite side of the fusible resistor, I got almost zero volt. This usually indicate the resistor already opened circuit.
Since this can be a fusible resistor with low ohm (2.2 to 4.7 ohm), there is something had shorted that caused the resistor to open. Chances is extremely high the sound output IC was shorted.
When I set my meter to Ohms range and checked on the sound output IC vcc pin to ground, I’d got .001 Ohm that means it had a dead short . this can be it why the fusible resistor was open circuited.
I replaced both the resistor and also the sound output IC and powered it on, i used to be very happy to hear the sound came back again.

Assuming if there's no short and therefore the VCC pin to the sound output IC measured 21 Vdc, then my next step would be to direct replace the sound out out IC and retest. If still no sound then i will be able to reprogram the EEpr
