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: 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

I have a Sharp Aquos LC-C3234U TV. I can turn it on and than the screen goes black but the volume is fine. What can I do to fix it?


Check its back-light inverter board, and the voltage comes to it from the main power regulator board. To get some details, http://electronicshelponline.blogspot.com/ Pull up older posts.

I have a sharp Aquos and the input button will not come on black


If you get sound but no picture (black screen), There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Sharp Aquos LC-32D4OU


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.
