If you are a DIY then once you pull back off you will see power supply board and there are caps that goes bad in these sets. They bulge out and sometimes explode. You tube has video on how to fix some sets, this is the same procedure

Sharp Aquous will not turn on.


I would check the System Cable that is linking the box to the TV. Then, press the small button called CLEAR in the front of the box. The button should be behind the flip cover on the front right below the PC input ports.
Let me know if this solution works.

Sharp LC-37HV4U not turning on


hold down the input button and volume - while the MAIN POWER BUTTON IS OFF. Then turn on the main power button while those are held down, the light on the tv & avc box will turn green, then immediately let off the 2 buttons and press volume +. Next step is to repeat the process about 20-40 times & the TV WILL WORK!. I have read that this may have something to do with the energy star compliant commads that can changed through the serial port.
