Re: Sharp LC-37SB24U will not turn on
From the information you have provided failed capacitors in the power
supply is likely causing the problem. The safety circuitry shuts the TV
set down when it detects a problem. This model of TV has over 2,000
parts which include millions of transistors inside the integrated
circuits. The capacitors will change value, leak and become defective.
Resistors will change value and burn. Integrated circuits and
transistors can go bad. This can cause other components to become
defective, which can have a domino effect and cause other parts to fail.
Replacing one defective part may make the TV operate for a short time
but the part will fail again since if the parts that caused the failure
to begin with are not replaced. The only way to know for sure what is
causing the problem, which parts that are no longer within factory specs
and for proper repair all the electronics must be diagnosed by someone
with the correct electronic test equipment and the skills to use the
test equipment. The repair should cost about $250 if carried into a TV
repair shop. A small TV repair shop will often charge less than a large

I can tell you 100% that the problem that you are having will be a service issue. I can also tell you that your limited warranty covers in home service from sharp. Give them a call 1-87-SEE AQUOS(the advantage line that will get you through much quicker). or the 1-800-BE-SHARP and let them set you up for service, sharp will take care of that as long as the purchase date of your tv was within 1 year. If you dont want to go through that, I suggest taking the tv back to where you got it from if they will accept it because unfortunately, this problem can ONLY be resolved through service. good luck & keep me posted
This same thing happened to me, but not until I fiddled with all of my remotes, trying to see if it was an input issue, battery issue, etc. I finally unplugged the tv from the wall and plugged it back in. Nothing. Then I went to take 5 minute ****. When I finished, the Power & OPC lights were blinking, and out of sync. I pressed the power button at the top of my TV and got a picture.
