The bad news,your set needs a new inverter board installed.With persistence to sharp,you might be able to get them to pay for the parts.

Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

SOURCE: Sharp aquos lcd screen goes blank

i was having these same problems with the screen going black, and i found that when i hit the back of my tv it would work sometimes. so, i improvised on some of the advice on this page and so far no problems. here is what i did (its very easy):

1. lay the tv on the floor and take off the back panel. (i think 12 screws)

2. on the right side of the tv (as you are looking at the back) you will notice a large metal covering that is held in place by 6 screws. unscrew these and remove the metal cover.

3. you will notice that the three screw holes on the left side of the board have some sort of metal or solder around them, in sort of a star pattern. when i looked closely i noticed that most of the metal (solder) was tarnished, or kind of blackened. (this must mean that the ground screws werent getting a good connection and this would explain why it would work sometimes when i hit it because it would vibrate the screws enough to get a good connection! )

so, take a pencil eraser and erase all the black or tarnish off the metal surrounding the screw holes. thats it! (to be safe i took some sandpaper and cleaned up the screw holes on the back of the metal covering, but i dont know if that was necessary)

at this point i followed another gentleman's advice to do a hard reset. this involved unplugging the 8 connections although i dont know if this was really necessary because i believe my problem was a ground issue. i did it just to be safe. his advice is on this site if you want to do this step.

4. i put everything back together and it worked! i performed a soft reset at this point which puts your tv back to factory settings. just go to menu>setup>reset>return to factory settings? yes
this will turn your tv off and back on. that's it. so far so good for me.

SOURCE: No sound on Sharp Aquos 37' LC-37D4U

I had the same problem on my 37" Aquos. Sound went out about 8 months ago after 4 years. Technician said it was the Sound Power Supply. Total cost to fix was $440. $250 for the power supply and $170 for labor. Has worked fine ever since. When I asked for the old power supply he said he had to give it back as a trade in. I don't believe that so I don't really know if the power supply was the real cause.
Now I've lost sound on 4 channels on my 20" Aquos. Great picture, but wouldn't buy another Sharp product.

HI, MY NAME IS S. A. ANSARI, I HAVE A SHARP AQUOS LC-32A66M LCD TV. ONE DAY SUDDENLY GOES INTO STAND BY MODE. NOW WHENEVER WE TRIED TO TURNED IT ON, IT ON FOR 30 SECOND I.E. WE CAN SEE PICTURE, HEAR SOUND...


Hi Ansari
It sounds like a main board problem. The control voltage that goes to back-light inverter board; from the main board, goes down. Contact any service technician. This is not a user repairable fault. Gopakumar Gopalan Google

Sharp Aquos LC-32D41U pictures problem


I have had exactly the same problem. Sounds daft but by not using the remote, and only using the power on/off switch on the TV itself, it is working perfectly...no idea why
Use the remore for changing programmes etc but not for on/off
Try it anyway because I know how annoying this is
