Remote control won,t work


This is how to complete a remote reset for a Sharp television:

Turn off the television if it is on. Unplug the television. Please leave it unplugged. Take the batteries out of the remote control. Leave the batteries out of the remote control. Is the television still unplugged? Yes? Good leave it that way. Are the batteries still out of the remote? Yes? Good leave them that way. Point the remote at the television's remote sensor. Hold the power button down for 30 seconds. Release it. Press and release each button on the remote control. Plug the television back in. Turn it on with the power button on the television itself. Replace the batteries. Try adjusting the volume. Hopefully the remote works. If it still doesn't work the remote sensor on the television could have gone out or you may need a new remote. http://www.sharpusa.com may have a remote you can order or http://www.replacementremotes.com but if that isn't the problem you may or may not be able to return the remote.

The remote control sensor on my new television does not work. I have tried several remote controls and none of them work. Is there a way I can fix this myself or do I need to wait for a technician to come...


Unfortunately, only remote can do.

If you have a philip screw driver, soldering iron and soldering lead at your home and have the guts to make the DiY, then, here is what you need to do.

Turn off the TV
On your tv, locate where the ir sensor (infrared sensor). Open the back cover of your television using the Philip Screw driver. Manage to access the small pc board where the ir sensor was attached. Examine closely the ir sensor board. Using your soldering iron and lead, try to resolder all the terminals in the ir sensor board.

After you resolder, then, return it back. And Turn on your televison.

Hope this helps!

The remote stopped working


Hello,

If your remote stops working all of a sudden, first thing you need to check on is the remotes battery, replace the batteries and try to test it again, if it works, it means that simply solved the problem and if it does not, then it means the problem is from another source.

Try to change channels from the television by pushing the channel buttons that mostly used to be by the side of the television, to see if it changes channels, if that does, then you need to find out if the remote sensor on the television is not rusty, for that you will have to unscrew the television open and access the remote sensor.

You will have to try out another similar remote on the television to see if it works, if that works, then it means the remote is bad and need to be replaced with a new one. And if it does not work, then it means loosening the television is the next thing to do to check if the remote sensor in the television is bad.

Unplug the television, then unscrew it apart, be sure to allow television rest for some time to allow the high voltage dissipate, after that you start the work on the television, then you disassemble it to see if the pins holding the remote sensor are not rusted, once you find them rusty and broken off the board, you can either replace the remote sensor or resolder it properly back on the television.

After doing that, reverse the process to reassemble the television back and plug it, then test the remote and it will work once again.

Take care and good luck

Not able to turn tv on with remote


First try changing the batteries.
Next make sure when you press function on the remote control the red light on the remote displays under tv

Next try a remote reset:

You have to unplug the television after turning it off. Take the batteries out of the remote control. Point the remote toward the remote sensor (bottom right hand corner of the television set). Press the power button on the remote control and hold it down for 30 full seconds. Next press and release every button on the remote control. Next plug the tv back in and power it on from the power button on the television itself. Replace the batteries. Adjust the volume using the remote control. If that works the problem is solved. If it doesn't work you may need a software update, a new remote control, or repair to the sensor on your television.

To see if your remote control is working look at it through the viewscreen of a digital camera. The digital camera must be turned on and ready to take a picture. Next press a channel button on the remote control. Do you see a bluish white light? If so the remote control is ok.

My Mitsubishi projection TV will not produce audio or video


Hi,
Two things are involved to cause that problem, tv remote control and remote sensor in tv.
Upon verification of remote working, it would be confirm that remote sensor in tv is defective and need to be replaced.
Remote control sends infra red light signal to tv and we can not see that light with naked-eye, so need digital camera or cell phone camera to see it by watching remote front through camera, press any keys on remote, if you see infra red light is blinking in remote front that means remote is working and remote sensor in tv will be replaced.
If no light blinking on pressing remote buttons confirm that this remote is defective and buy new remote.
Let me know if you have additional question.
Thanks.
