SOURCE: My Sharp Aquos 46" LCD

Digital inputs on Aquos TV's are "always on," usually the HDMI inputs and DVI inputs. As opposed to analog inputs 1, 2, or 3, are only activated once something is plugged in.
Try plugging in another HDMI sources into input4 or 5, if its still not working, the TV needs a new Main Board. Try calling Sharp 1-800-237-4277 and locating a local service center in your area.

SOURCE: sharp aquos 46 picture disappears intermittently

it might mean there is an intermittent connection or cold solder joint somewhere inside the set.
But I wouldn't just settle on that.
Here are some other things to check:
1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?
Here is what I suggest:

ONE: Give it a hard reset. Possibly the software codes in the power management are corrupted. Just unplug the tv line cord for 4 hours. That will reset everything internally to factory defaults.

TWO: Give it the old whacking test. Just bang on the cabinet in many places with your hand or fist. That will restart any cold solder joints or loose connections.

THREE: If the above procedure does not help, then you will have to call in an expert tv tech; OR just live with it and put in a line cord switch so that when it is OFF, it is really OFF.

SOURCE: Sharp Aquos LC-46D64U need to replace broken tuner

actually you dont need the tuner you just need the rf connector itself which you can easly pick up at a radio shack for a few bucks. you can DIY it will take a bit of soldering and time. First take the broken connector to radio and look for a close match, longer leads better you can always cut to fit.
remove board from tv and un solder the tuner. if solder does not seam to melt apply some fresh solder and then unsolder. pop the tuner lid of carefully both top and bottom to gain access to the circuit. cearfully remove any remains of the old connector. Now find the hole where the last part was and insert new RF connector adjust and cut the lead if nessary and resolder to circuit. place both caps back on and resolder tuner to board.connect board to ther circuit and test.

SOURCE: power supply bad on Sharp Aquos LC - bad board - schematic to ID?

Buy the green light going on means Standby is ok. Next, would be to locate the plug coming from the main board to the power supply and find the post that says PO which means power on. With your meter on that post, press the power button as see if the reading goes High, if it does then the main board is able to turn on the power supply. Next, find the plug on the power supply that goes to the inverter( the long board on the side) remove it and see if you have 24 volts coming out of the power supply when you press the power. If you do, then the inverter board is bad, if you don't have 24 v, then the power supply is bad. There are NO diagrams available for these set other than a flow chart if you can find one. A regular svc tech does'nt need a manual for these anyway.

Let me know how you do Kathy ?

Sharp aquos 46 in


Check its fuse at the power supply board. If found burned, make sure that there is shorted component/s. Try to repair it. If the repair cost exceed than the cost of a new one, replace it as card basis. It will be more better than try to repair these boards.
Contact the authorised service center for Sharp, to buy a new one.
