My sharp aquos lc-42d65u is not responding to my remote control . another word my t.v does not read my remote control at all. can someone help me to fix my remote ?

From page 8 of the manual:

The POWER indicator on the AQUOS television should light GREEN indicating you have power to the AQUOS television.

If the POWER indicator on the AQUOS television still does not light up, press TV POWER on the remote control to turn the power on.

IMPORTANT:
IF THE UNIT DOES NOT POWER ON - UNPLUG THE AQUOS TELEVISION FROM THE OUTLET AND REPEAT THE INSTALLATION STEPS.

IF YOU STILL ENCOUNTER NO POWER, PLEASE CONTACT US AT 1-800-BE-SHARP

First of all... forgive me me if its a dumb question. But... How long has it been since you changed the batteries in the remote?

Check the cable box for the manufacturers name and see if that isn't listed in your owners manual.

if it response to tv controls ,, remote bad

try unplugging tv.

it is clearly a case of "you got ripped off" just like me

Sounds like your powerboard, take it back or call tech for replacement, dont settle for this, you paid good money for a working tv

I got a a sharp LC-32D43U and for my motorola cable box i use hte code 31 from jerrold, i take it from the manual and i got it tryin every single code unti i get one that works.

Hope it works for you

Unplugging my TV for 15 seconds (longer actually - at least a minute) made the remote and the satellite TV remote both work again with the TV.  Thanks for the tip!
