Question about Sharp LC-37D6U 37 in. LCD Television
Same problem as Sept. 7, 07 description...no audio and no apparent reason for the problem. Will work if the TV is turned off and on (and we also hear a "clicK" after the set is turned off. Thought maybe we reset some features inadvertantly but cannot find anything within the menu that seems to make a difference. Very unpredictable.
That click sound when the tv turns off is normal, that is
just the relay from the power supply shutting off.
When you turn the tv on, do you hear a faint “pop” noise from the speaker? If so, the problem is with the heat sink under the audio IC. Over time, the heat sink will lose its consistency and start to melt, thus shorting out the audio circuit. To fix, you’d need to clean off the melted residue on both sides of the audio IC as well as replacing the heat sink with a newly redesigned Sharp Heat Insulation Pad. It’s a pretty complicated fix, I suggest calling your local authorized sharp service center to fix this problem. The part is inexpensive, so you’re most likely looking at a labor charge (maybe around $200ish) for the repair if they are not marking up the price too much.
