How to fix my sharp aquos LC42D69U lcd tc

Hi. I have a sharp aquos Lc42D69U, TV will turned on, the sound works, but there is no picture. This problem affects all inputs. Sometimes I can watch Tv few minutes before the screen go black. So I will turn it off and back again, the image will be back for few minutes until go black.... and sometimes no display at all,just black. Also the image display will flash. After browsing some sites, I find out it may be the backlight. So I order a new backlight inverter board and installed it but still not working.. could it be the main board or T-con... thanks

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.

What are the 4 screw sizes on the back of my LC42D69U tv that are used to mount the tv onto the wall or the tv stand?


They are metric and you can most likely go to a hardware store and see if they will let you borrow a series of them to see which ones fit. The only issue is to make sure they are not too long.

Hi,
Maybe the cords have the problem.
You might have to pull and reconnect the cords and do the same basic turning on/off of the Tv.
Or you might also check the positioning of your Tv, example : are there stereos or speakers near or beside the Tv? it causes magnetic reaction and causes the screen to not work properly.

Sharp aquos 46d62u has sound, but no picture


We have the same problem with our 32" Aquos. Turn on the TV and after a couple seconds the picture goes out but still have audio. So this solution doesn't permanently fix the problem, but it works instantly to get the picture back. With the TV turned off, tap the side of the set twice with the palm of your hand. Turn the TV back on, and VOILA, you have a picture. I know the last thing you think to do is to hit your TV to fix it, but that is often how my husband tries to fix things...this time it worked!!
