20 Most Recent Sharp Aquos LC-37G4U 37 in. HD-Ready LCD Television Questions & Answers

Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

The ocean sound is 'noise' which means a bad connection. Best thing is to unplug & plug back in all cinch & scart etc cables, while turned off, of course. do this a few times for each cable, then turn it on. Sometimes it is the headphone jack, have you used it recently? Try plugging & unplugging the headphones quickly a few times, that normally solves the problem. If you still have a problem then it's internal and the TV needs looking at.
