Did any of this suggestions work? I'm having exactly the same issue over here, I did the "remove the batteries and touch all the buttons" thing and nothing, I guess I'll have to carry out the more technical procedures

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.

SOURCE: I have a Sharp LC-32D44E LCD TV. Purchased Oct

If the red light stays on and the tv does not react to any input from buttons or remote... the problem is one 7 pins integrated circuit on the upper side of the power board .the ic is situated on the right side of the power socket .It costs about 2$ and can be replaced by someone with mimimal electronics skills and a 30w solder iron .

I had the same issue with my Sharp Aquos 52 inch LCD TV. I called Sharp. The tech had me unplug my TV, take the batteries out of the remote (TV remote not cable) and press all buttons on the remote (including the buttons under the flip top at the bottom of the remote). I did this, put the batteries back in and plugged in the tv and everything worked. I had gone 4 months having to use the surround sound for volume and turning the TV on and off by hand. This took 2 minutes to fix.

Hi Ansari
It sounds like a main board problem. The control voltage that goes to back-light inverter board; from the main board, goes down. Contact any service technician. This is not a user repairable fault. Gopakumar Gopalan Google

Need a Code for Dish Network Remote

You can power scan for the code.
Turn ON the electronic device you want to program the remote to control.
Press the TV Mode button on the remote until the appropriate mode light is flashing.

Press the Power button. The mode light will stop flashing and stay lit.
Press the Up or Down arrow button to set the remote to the next code. The Down arrow button scans backward and the Up arrow button scans forward.
When the correct code is reached, the device (whether a TV, VCR, or other) will turn off.

Press the pound key button to store the code in the remote control memory. If the code is valid for your remote, the mode light will blink 3 times.
Turn the device back ON by pressing the Power button.
Press sat mode key once you power back on the tv to be able to operate the receiver box.
Try some other functions to make sure you have the correct code. Occasionally the Power button may work when others do not.
If the other buttons work you are finished.

.
If the other buttons do not work, repeat the previous steps. The scan will resume from the last code stored.
The mode light will flash rapidly when the scan has returned to the starting point and all codes have been tested for that mode. The remote control may not control some device models.

Sharp 32" aquos LCD tv, will not power up with remote or switch on set, has power (120v) to end of cord where plugs into back of tv

This is usually some sort of power supply shut down problem the TV has detected a major fault, and has shut down the power supply to avoid a fire or explosion.. you need to get this unit serviced by a reputable repairer also always ask for a 'Quote: so you know weather to repair or replace.

My Thomson 40kw611s will not work when I try my remote. The light flashes on the switch and it stays in standby mode. It is not the batterys,fuse or anything. Can you help?

If it starts flashing when you press the power button on the remote, the tv is getting the right signal from the remote. You have a problem inside the set.

T.V. won't allow me to adjust color and sound...

Chepe_77,

You are absolutely correct. The reason why you cannot change your audio and video settings are due to the fact that you are in "Dynamic Fixed". Which is one of your many av modes. Av modes are different preset color settings and dynamic fixed is the only one that will lock your settings. Best Buy set it that way so that people could not just come by and alter the settings on the unit. AV modes are on all sharp lcd products and even though you have the wrong remote you should have an av mode button on the remote that came with it. Try pressing the av mode button and see what happens. When you press the av mode button, you will see your av modes change at the bottom of the screen. However, the issue still remains that you have the wrong remote. So there is a chance that you may press the av mode button on the remote that you have, but it still will may not work ONLY because you have the wrong remote. If the remote you have does not work, I GUARANTEE that pressing the av mode button on the proper remote will take care of that. If you dont want to purchase the remote from sharp, www.partstore.com is a good place. Good luck to you
