Question about Sharp LC52SB57UN LCD TV
Have a sharp lc52sb57u. While using the set the volume all of a sudden races up to 60 (max) and I have NO use of the remote or side panel controls, except for the power button. Any ideas of the cause or how to fix? I have tried unplugging the set, which works sometimes, yet the problem persists and comes back. I have tried removing the remote from the area, which has no effect.

SOURCE: Sharp Aquos turns itself off
My LC37D6U had this problem, thought that I was going **** at first, came to find out that there was a firmware issue with the system. I got ahold of the updates for my particular system and just applied them. ** issues turning on and off now, just the sound going dead after 18 months.

SOURCE: volume issue
I have the same problem. When I adjusted the volume on the cable box, it was solved. Turn up the volume on the cable box, and when you use your remote, it's super loud, even at midway!

On this unit if you do a fact reset it should fix this problem steps as follows. PS you might need 2 people
1- unplug unit from back of unit
2- on the key pad on the tv hold the input and vol dowm buttons
3- while holding the buttons plug the tv in, keep holding the buttons until the screen comes up.
4- once the screen is up there should be a white K in a blue or green box.
5- next, on the key pad on the tv press the channel and vol down buttons once.
6- a menu should pop up
7- using the sharp remote,locate the directional pad
8- press the down button once should bring you to a 2nd page
9- top should state FACT INIT press the right arrow once to turn on, next a series of back slashes come up.
10- screen goes green and says INIT Successful
11- unplug unit from back of tv wait 10 sec then plug back in. tv should turn on by itself. should be back to as new.
If you get to step 7 and the remote still does not work then you need to replace the ir sensor board (aka) LED unit per Sharp.
if needed here is the orignal part info DUNTKE868FM01 about $12.00+ tax
