Question about Sharp LC32SB28UT 32 in. HDTV LCD

SOURCE: Sharp Aquos Won't Power On
I have the same problem with my My LC-42D62U WHen i watch certain DVDs, (so far it happened on SAW III and RUNNING SCARED) during certain parts of those movies my TV will turn off and i cant turn it back on unless i unplug it and plug it back in. It only turns off on specific parts in the movie, i have no idea why...like the same exact parts...so i pretty much have to pause the movie with my remote once my TV turns off then when i power the TV on again just resume the movie and its fine...but if i rewind to that part again it'll power off again SAW III only had one part like that....but RUNNING SCARED had about 3-4

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 you use a digital cable box, it could be that the volume on that isn't turned up all the way. I didn't even realize the box had volume controls until 2 years after I got it...makes a HUGE difference now
