SUBJECT: Blocked Sound Problem on MB6x (MB60, MB62)
< Objective >
This service bulletin is being published to inform about a solution to the issue at subject.
< Information >
• TVs rarely would block the sound, after it worked for 2-3 hours.
• Root cause of the problem is due to the sensitivity of the audio input level of Audio IC, U168.
Therefore, component change will solve this problem, which are exist on below positions 1uF instead
of 470 nF
• Relevant problematic material positions are; C1075, C1076, C1077, C1078
• Vestel change references are;
# 2012001110 Change date: 13-September-2012
# 2012001092 Change date: 12-September-2012
• Problematic part code: 30050557 CAP SMD 470NF 6.3V K X5R (0402) RoHS
• New part code: 30050554 CAP SMD 1UF 6.3V M X5R (0402) RoHS
< Instructions >
• Dismount the capacitors –470nF– at the C1075, C1076, C1077, C1078 positions on the MB6x chassis
