    It will shut off again in a few miniutes. It get's worse the longer you keep trying to use it. Thanks

    .Yes picture and the sound are perfect. It started doing this about a week after the warrantee expired. Have you repaired these before? Thanks Rick

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

Sharp Aquos LC-20B6U-S TV NOW HAS NO SOUND OR PICTURE. IT APPEARS TO COME ON BUT WITH NO PICTURE OR SOUND.


This can be caused by many different things. Check power supply fuses. If ok suspect inverter board which drives screen. Check for bulging capacitors and open transformers or just find replacement cost using numbers on board. That may fixya.

SHARP AQUOS LC-26P70E - Clock


Most TV's don't change with daylight savings time, since they do not operate with a date, just time. You will need to change it via the remote.
Good luck

Sharp Aquos power up delay


Have you checked the voltage in your home?
How about the way your outlets are wired?
Do you have too few outlets and many other things on the same circuit?
Sometimes you can have a continual problem with it like a brown out.
My daughter and her husband were living in an apartment that had only one good electric circuit and another iffy one, needless to say, they moved to another better apartment.
Brownouts were occuring all the time, because of insufficient current when so many things are on one circuit.
You may have a situation that has caused a power surge and caused the same problem with both tv's.
The best protection is a GFCI outlet installed where the tv is AND a power strip that protects against lighning.
Let me know what you see.
