I have the same model about 3 yrs. old. No picture but has sound.The problem is a loose contact in the circuit board. First unplug the tv and remove back cover. The circuit board opposite side of the input plugs. Remove this circuit board and clean the mating surface between the board and the mount. Reinstall board and tighten the mount screws. Reinstall back cover. Thats it. This is where your lost contact is occuring. Good luck

Modification of the inverter unit usually takes care of this problem.

What's the reason to cause the TV shows up only sounds but not pictures?


I may have a work around for you. I also have this model and the same problem. after trying many many sequences of turning on and off with setting changes I came across something that works for me 100% of the time. Turn off the tv. Place your left and right hand on the top corners of the tv. flex gently back and forth. turn tv on. this works for me. I can only say that this tv has some quality control issue(s). it will be my last Sharp product. this was a lowest bidder produced by a company other than Sharp with a Sharp label on it. good luck.

Sharp aquos model LC-32D40U screen goes black


The Sharp TV model LC32D40U / 41U "Black Screen problem" is a very well known issue. The inverter is losing ground contact which will prevent the back-light from staying on. The solution is to re-tighten six screws on the inverter board. You also would want to clean the copper contacts on then bottom of the inverter where the screws go through. Access to the inverter board will require some disassembly. Plan on taking at least three hours to repair. See the photo for the location of the screws. Use some "blue" locktight" on these six screws. There is actually a Sharp Technical Service Bulletin that describes these screws. Sharp wants you to replace these screws with a newer version. They cost at least $2.50 each! I think my method will work just as good using the "Locktight"_548.jpg_547.jpg
