I've had my Sharp Aquos LC20E1U for a number of years. A couple of times recently it just shut off on its own. It started OK again the following day. However, last time this happened, it wouldn't even...
service menu procedure text changed by midge to work with Sharp LC-32P70E & probably the same for similar models.
There are probably ways of really messing up your set if you do the wrong thing from the service menus, so do this at your own risk:
To enter service menu, make sure the set is plugged in but turned off at the power button on the top of the tv,
then while holding both input button and volume down button, push the power button. Within about 5 seconds, the set will power up keep holding the input and volume down buttons until a small "K" appears in a box on the left side of the screen. Then press and hold the channel down and vol down buttons at the same time to enter the service menu.
Once the service menu is displayed on the screen, you can get the screen to display different levels of solid grey by pressing the number keys on your remote. i.e. press "1" to get a relatively dark grey, 2 for a lighter grey, and so on up to 6 which is a bright white screen; 7, 8, and 9 don't appear to do anything. (this was for adjusting grey levels, other settings are available too) Press any number a second time to return to the service menu...
Not sure wether the grey background settings apply, but for entering the service menu it does.
I think to get out of service mode you have to disconnect the TV from the mains and wait about 30 seconds.
it's some time since I used the service menu on the Sharp Aquos but I do remember you can do a full reset to factory settings as well as turn on, off and reset certain system settings too you will just have to experiment with the remote keys, I think the colour fastext key access different menu levels etc but as I said I am unsure, at least this procedure will get you there so you can try for yourself.
Hope this helps
Please come back to let me know if the service menu procedure works for you.
