Sharp Aquos turns itself off
How many times per second does the POWER led blink? (dont worry about the OPC).
1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board
You can buy the parts online and fix if yourself!!

The tv menu keeps popping up
The reason your television keeps popping up the menu is simply because, either the remote or the televisions menu button is stuck.
To test if it is the remote, remove the battery from the back of the remote and try to operate the television from the buttons on the television to see if it works, if it pops up, then it means the problem is not from the remote and its from the television.
Either ways you have to open the remote and clean the panel with naphthalene, then adjust the menu button on it. or you can as well get a new remote for your television if you cannot clean it on your own.
Also to fix the television if it is detected as the fault, get the appropriate screwdriver, open up the television, then try to locate the menu button, then you adjust it and try to operate with either the remote of the menu key on the television.
Once it is seen to be working, ensure that the television is properly coupled back.
Always make sure the keys on the coputer and the television are not pressed too hard.

Lcd sharp tv flashing green light
Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.

Thethe tv will not come on and power and theopc is
Ok This is how to troubleshoot the TV, there are lights on the front and you are mainly concerned with two of these lights (the power light and the OPC light). I) If non of the lights come on then this is a AC Power failure (There is a loose connection or you need to check the Power/Inverter unit or the Main unit) II) If the power light is blinking at a rate of one blink per min and the OPC light is off (then there is a CCFL backlight problem) III) If the power light is blinking at a rate of two times per min and the OPC light blinks at a rate of one time per min (13V/UR10V failure you need to check the Power/inverter board or the main board). IV) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of two times per min (3.3V Main Failure check power/inverter board or Main board). V) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of three times per min (UR6V failure check power/inverter board or Main board). VI) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of Five times per min (Panel 5V failure check LCD control unit or control panel).

Sharp aquos lcd screen goes blank
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.

No screen and the power and opc light flash on lc-46e77un tv
Final Up date, The TV is fixed, with my problem it was found that the units Mainboard was defective. If you go to replace your Mainboard MAKE SURE THAT YOU PURCHASE THE CORRECT BOARD AND VERSION NUMBER OR IT WILL NOT WORK...... for example KE833 XE833WJ and the most important part, look for the version on the White lable markings, mine was FM11S it will be some FM number that will be used on your Set. Hope this helps you solve your problem.
