Question about Sharp Aquos LC-46D62U 46 in. LCD HDTV
Posted by Anonymous on
Did any of this suggestions work? I'm having exactly the same issue over here, I did the "remove the batteries and touch all the buttons" thing and nothing, I guess I'll have to carry out the more technical procedures

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.

If the red light stays on and the tv does not react to any input from buttons or remote... the problem is one 7 pins integrated circuit on the upper side of the power board .the ic is situated on the right side of the power socket .It costs about 2$ and can be replaced by someone with mimimal electronics skills and a 30w solder iron .

I had the same issue with my Sharp Aquos 52 inch LCD TV. I called Sharp. The tech had me unplug my TV, take the batteries out of the remote (TV remote not cable) and press all buttons on the remote (including the buttons under the flip top at the bottom of the remote). I did this, put the batteries back in and plugged in the tv and everything worked. I had gone 4 months having to use the surround sound for volume and turning the TV on and off by hand. This took 2 minutes to fix.
