SOURCE: 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.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

I called up Sharp, and if you are a part of Sharp AQUOS Advantage Program you get free in home service.

They were very nice about it, and I already have a technician coming to my house on Saturday and I called on Wednesday.

I doubt Sharp's policy alot less now!

60" sharp aquos power indicator is flashing one short flash and one long flash and keeps repeating the sequence


POWER LIGHT FLASHES ONE SHORT AND ONE LONG FLASH.
What is the problem? THE PROBLEM IS THAT ONE OF THE LED's STRIPS IS BAD!

SHARP AQUOS LC60LE810UN RESET INSTRUCTIONS

1)Plug in TV to electric current First then wait until LED start flashing.
2)Press Volume DOWN [ - ] HOLD BUTTON.
3)Press Channel UP [ ^ ] HOLD BUTTON.
4)Press Power [ (') ] HOLD ALL three buttons until LED stops flashing and then release.

    ┬ĚThis will reset the TV in order to fix the problem.
    ┬ĚTHE FIX IS TO REPLACE ONE OF THE LED's. You need to open the back of the TV and you will also need to remove the front cover and panel to get to the LEDs. The TV will need to be placed facedown and on the backside. This is a 2 person job to turn the TV on its sides. Be careful with the white computer connectors (wide white strip) at the base of the TV where the TV stand sits. You will need to disconnect this in order to get to the LED's.
    Once you have the LED's exposed, you will need to unplug one by one by placing the new strip next to it until the unit turns on. You will have to use the RESET procedure above if the Power lite flashes. The Power lite MUST BE ON SOLID - no blinking in order to test the strips. The LED's will flash, but still one of them will be burned. Even if you stare and all the strip light-up, you will still need to check one-by-one!
    Once the TV lights up, your face will also light up with joy! Put everything back together and you are set. If you need the complete instructions which come from Sharp as to how to disassemble the unit, please send me an e-mail to LGTR61@YAHOO.ES. Please note I don't check this address daily, so a few days wait may take for you to receive the instructions.

    Where can you buy the LED's - try searching Yahoo.com or Google.com for resellers.

Sharp Blue Ray and Sharp Aquos TV were working just fine, now blue ray not recognized by tv; screen stays dark but the blue ray appears to be operating. Have tested the blue ray independently and worked...


A refurbished set? If blue ray is not built into set the issue is with the set--maybe the reason set was refurbished.....If have not tried it unplug set for a while and reconnect with set turned off.

Sharp 52" Aquos LCD Will Not Turn ON-Blinking LEDs


I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.

Just 18 month old TV and out of warranty.
