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.

White line across screen


If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.

Take it to a repair shop.

Thin blue line


I am a Sharp Servicing Technician. You posted this before. Ive got the same model TV as you do LC46D62U. I think the line you are experiencing is simply the broadcast. I notice it on some HD shows that broadcast the side bars. (Always on the Ellen Degeneres Show). Ive taken some picture.

1) Here's the line on the left that i experience

2) Later on in the broadcast, it goes away.

One way to check if its a TV problem or not. When the line shows up again, hit the MENU button on the remote. If the line appears to be "behind" the menu, then it is simply the broadcast.

If the line appears to be "on top" of the menu or shows right through the menu, then it is a TV problem.

Im thinking the reason it takes hours for hte line to appear is because it only shows up on certain shows or certain HD broadcasts.
