SOURCE: my sharp tv model 21V-W70M has no sound, the speaker is ok but no soumd coming out.

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Surf the site with patience.

Check the voltage goes to audio amp circuit section.
Check speaker/s [If there is two speakers, both of it should be checked for coil continuity]
Check whether the audio is muted.
If all these are OK, check and replace the audio output IC.

Replace all other capacitors one by one, and check. Never left any one out there. REPLACE ALL. This is the only way to make it right!!!!!

My Sharp TV's Stand-by Mode (Red), Model 14V-K80M, turns ON, turns GREEN when the other button is pressed but turns back to RED after a few seconds.


Hi

Your tv set may have an overload in the supply line. Check its rectifier diode and filter capacitor. Another approach is to check if the DC supply line of the switch mode controller IC (UC4842 for exemple).is present (10/12V). If these are OK, replace the switching MOSFET transistor and check the source resitor for open circuit.
