    Hi Joe, guess the rare event is finally here! This is exactly what I don't wish to happened.

    The only other occassion that works is when I tape a small magnifying glass right up against the receiving lens on the tv set, but only works on a straight line , and I'm sitting on a 80 degree angle...

    Thanks anyway

Hi,
1) Try resetting the code search / programming
2) Try quickly tapping the OFF command key (opposed to holding it down for 2+ seconds)
3) Be sure there are fresh batteries in remote
The remote could possibly transmit a lower frequency setting for the 'OFF' state than it does for the 'ON' state. See if there's a setting for ON/OFF commands on the remotes 'Settings Menu'. You can also check the owners manua for your universal remote,l under 'POWER options ON/OFF. Make sure nothings blocking the IR sensor on the TV. Also bare in mind it may not be the remote but rather the TV's IR sensor.
However,
If still no results then send it back and obtain the original remote for the TV, which is always the best option.

Hello henrylee. In a perfect world infrared remote controls have a range of about 10 meters. That said, the batteries must be fresh and new, their must be a clear path to insure direct line of sight for the signal to travel straight to the infrared receiver eye on the front of the tv.

For instance, if the tv is in a cabinet and the cabinet door is partially blocking the line of sight you will have a problem.

Do this. First of all locate the infrared receiver on the front of your television set. Clean it with a wee bit of window cleaner and a tissue in case it is dusty. Next Sit where you normally do and insure that there is nothing in the way of the traveling signal such as the cabinet door, a knickknack, a plant leaf, etc.

IF you have fresh, new batteries in your remote it should work fine. If it still doesn't respond as it should, you may have to replace the infrared receiver unit in the television, but that is a rare event. Joe

4 thumbs up please. ty.

Since the control is recognized at a distance for one function but NOT the other, we can believe that the sensors are capable of the longer range. This is a guess, but something is de-sensitizing the receiver at a pulse rate near the code used for the shutoff. Look for ANY infared source that MIGHT be hitting the sensor, especially those that might have a pulse code being emitted. Such things MIGHT be a wireless headphone or speaker system. Try turning off ALL electronics and any non-incandescent lamps or dimmers in the room and retest the situation. The new LED lamps for instance might generate strong pulses that are confuse the decoder in your receiver.

    Since you addressed Joe, I am not sure if you investigated my suggestions or not. Can you think of anything that was done or changed around the time when this failed. Changing light bulbs to CFL's or to LED types in the room would be a possibility. The pulsing of these lights MIGHT be saturating the sensor at just the right pulse width to confuse the decoder. Also evaluate my previous suggestions. The key here is to look for a change that was made around the time of the failure... EVEN a street light that illuminates the sensor could cause this. Try this: Since the lense focused and allows the longer range, take the cardboard tube from a roll of paper towels and hold that as a collimator... If that will work at the distance, then the problem is truly interference and it will be EASY to isolate the source... Try turning off ALL other electrical devices one at a time INCLUDING any gass appliances the sensor might see....

How do I turn key lock off without the remote on a LG 47LH30-UA LCD TV.


Without a remote control, you can't. If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability? Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the site http://electrohelponline.blogspot.com/ Check this site too. http://remotesearch.blogspot.com/ Universal remote controls are available at most of the electronic spare part selling shops.

It's like the volume button is stuck


all tv sets with keyboards (controls) on the front or side use micro switches which the buttons engage--these are momentary switches=only supposed to work when pressed--they go bad in exactly the way you have described--cheap and after being pressed too hard will not disengage.

The way to prove this (by the way the switches have priority over the remote so it will not work if one is bad) is either access the vol up control and disable (unsolder the two pins) or test the switches with a ohm meter----

If the remote receiver is on same board as buttons/switches you are going to have to unsolder the offending vol button--if it is not you can usually disconnect the control board and set will again work with the remote.

either test/unsolder or have a shop do it.

If set works fine with vol disconnected just use the remote as you would likely have to replace the keyboard to correct it.

If you have the meter and are familiar with reading resistance let me know and I will tell you what to look for.

My unit requires remote control to operate remote control is lost what 2 do


Whether you have a thru the window model or a potable AC, the same controls that are on the remote are on the face of the unit. To operate it without the remote, turn the unit OFF and unplug it. Wait 5 minutes, then plug it back in. Wait 3 minutes & turn the unit ON using the controls on the front of the unit.. The controls will have reverted back to the original factory settings and you can now use the front control panel to operate & set the controls as you like.

If you want to purchase a new hand held remote, contact Haier Product Support 1-877-337-3639.

Hope this helped you and thanks for choosing FixYa.

Had the same problem ourselves.

Press set up on remote control.

Press the down button on remote control 5 times then press select.

Press the down button 2 times and press select.

Press select again.After 5 to 10 seconds the machine will switch itself off.

Turn off at the mains and then turn back on again and the dvd goes into preparing mode.

Go to AV channel and go through initial set up as you have just reset to factory conditions.Don't worry about any programmes on the hard drive they will still be there.Worked for us.
