You have standby 5vdc but you need to find out if the processor board is sending out the PS_ON to the power supply to turn on the 12 and 24vdc power supply section.
Heres is the service manual and training manual for your TV.

5v ok. start up relay doesnt activate


Sounds like you may need the power supply or Main PCB. The Main PCB usually has your microprocessor with your communication lines.

No Sound/Intermittent Sound


Check for any loose cable socket or any loose solder points in the audio output board of your TV. Check its speaker too. Connect an other speaker in place, and check to make it confirm that the speaker is good.

My sharp aquos lc 37d62u will not power on; the power light flashes 4 times, pauses and then repeats the 4 flashes. Does anyone know what this error code means? Thanks!


It is detecting shorted circuits or power supply problem, need in-depth troubleshooting. Inspect the power supply module first for any sign of bad caps with domed tops, DC output voltage readings check.

Sound only comes on after about an hour


I had the exact same problem. It was very frustrating to say the least. As it turned out the AV board went out and it cost $600 at total of $800 including labor, which makes this very expensive to replace. I actually had to think about junking the unit before it was even two years old.
