Onida tv no sound problem.

ONIDA TV ULTRA SLIM PCB.
SMD IC TDA11105H/N3/3/MD3.
FBT BSC23-N0151.
VERTICAL IC LA78141.
SOUND IC TDA7297SA.
STR G8656.
PICTURE OK BUT NO SOUND.
SOUND IC(TDA7297SA) PIN CONNECTIONS.
1.OUT 1+.
2.OUT 1-.
3.VCC.
4.IN 1.
5.NC.
6.MUTE.
7.ST-BY.
8.GND.
9.GND.
10.NC.
11.NC.
12.IN 2.
13.VCC.
14.OUT 2-.
15.OUT 2+.
SOLUTION:
1.Power on/Measure sound ic pin voltage(all pin)-----voltage missing mute pin No.6.
2.Tracing the voltage track line from mute pin No.6-----registor R608(47K) input voltage ok,but output voltage missing.
3.Open the registor R608(47K).----------registor defective.
4. Set new registor 47K.
5.Power on/Then--------

অডিও ic র ভোল্টেজটা ঠিক ঠিক জানা গেল,সঙ্গে অনবদ্য ট্রেসিং তো থাকলই।খুব ভালো লাগলো মাস্টার মশাই।নমস্কার।

Mute পিনের voltage circuit ডিজাইন অনুযায়ী পরিবর্তন হয়। 4.5V to 8.5V
