SAMSUNG 14" COLOR CRT TV REPAIR #3

IMPORTANT: WHILE WORKING WITH TV OR ANY CIRCUIT WITH HIGH VOLTAGES IT IS WISE TO USE AN  ISOLATION TRANSFORMER FOR YOUR SAFETY! (I need to buy one soon!!)
 
TYPE: KS1A14E4
MODEL: CZ-14E4V

SYMPTOM: PICTURE OK but NO SOUND (contd from repair #2)

FAULT DIAGNOSIS: 
- hurrah! this time it was easy-


- the sound ic, TDA8943SF, 6 W mono Bridge Tied Load (BTL) audio amplifier
- checked for some more shorted components, found none, everything seemed ok
- replaced it with a new one (₹ 70) and turned the tv ON

PICTURE OK, SOUND OK :)
