Hi,
When LCD TV lost its back light there would be no picture to view but TV does have sound. TV should have back light behind its screen to present picture on its LCD.
Two boards are suspected and any of them is possible cause of problem, Power Supply and Back Light Inverter, both are available in Shop Jimmy and I would recommend qualified TV tech should check TV before to order required board.
Thanks.

First off have you tried unplugging it for a good half hour and seeing if that will reset it? These tv's are actually known for locking up like this. Most likely I am guessing you have had this tv for a few years so the warranty is expired. Repair service gets kind of costly I believe for this problem its around 150-200$. Once you try and reset it let me know if you have any other questions or need further assistance.
Thank you,
Lee

Hi...
Unplugged the TV for 10 minutes, plugged it back in. then check.
Use component cables (red,green, blue) for picture instead of HDMI. Then also use a form of audio cable also, as the component cables will pass HD picture but no sound.
If this doesn't work the tv need new control board connected directly to the panel itself
should cost some what $200.

Thanks
Smith

Sharp Aquos 37" LCD TV sound quit


You could open up the TV and look for signs of burnt components then try to replace the components or try to find a replacement for the entire affected board on ebay or something. If you can find out what the problem is maybe the service person will lower there price. $600 does seem very steap, it should be something closer to $60 an hour with maybe the first $60 as an estimate.

The main power transistor in the power supply appears to have failed. It has also blown the fuse. Not a job for the DIY'er unless you have serious electronics experience.
