Check the remote control for its infrared emission. Check it with fresh batteries. If you wish to get more details about how to check a remote control, please visit this site. One among the posts have details about it. Surf the site in "Mosaic" or "Magazine" view. It will make surf easier.

Just bought tv today. Remote will work for a second then stop. Checked and there is a white light when I use a camera. What's going on?


Sounds like the crystal failure to the remote control's circuit board. There is a crystal that oscillates at a constant frequency, and this frequency is divided by some certain frequencies lower that it, when we press each button on the remote control, and an infrared LED at the front of the remote control will emit infrared rays according to this divided frequency, which in turn will absorb the infrared sensor inside the TV. In fact, if the basic oscillator crystal do not generate the adequate frequency, all the output frequency will differ from what it meant for; and TV set will either process it or not.
Just replace this crystal first. If it do not help you, buy an other remote control.

Lcd tv troubleshooting


Check for power supply trouble. The green LED on the front panel should light if power is getting to your TV. The "no signal" indication may mean no antenna or cable input is detected

Tv wont respond


The infrared signal that emits from the remote control is not with right frequency. Check it with fresh batteries. If it do not help you, replace the crystal inside the remote control's circuit board.

My Sony LCD model no CX52 There r white patches and background images are not visible Screen is full of pathes what to do


The LCD television is a flat-panel television which utilizes a Liquid Crystal Display technology. It has two layers of glass which are polarized and stuck together. The liquid crystals are held in one of the layers. These liquid crystals pass, or block the light, to produce images on the screen when the electric current passes through it.

However, the crystals do not produce their own light. The light comes from the series of fluorescent lamps at the back of the screen. There are millions of shutters arranged in a grid, which open and close to release and trap some of the light that is not needed to create images. Then each shutter is paired with a colored filter which produces a sub-pixel. These are so small, that when they combine, they create a single pixel, which appears to be a single spot of color on the screen. With the help of the fluorescent lamps, the images created by the liquid crystals become visible to the viewer.

LCD television produces high image quality. They can be made very thin, which makes them less space-consuming, and the user can hang them anywhere. This makes them appealing to buyers.

LED TV's are actually very much like LCD TV's. They also have a flat-screen which utilizes Liquid Crystal Display technology. The only difference is their source of light, which is at the back of the screen. The LCD TV uses fluorescent lamps, and the LED TV uses LED (Light Emitting Diodes).

There are two types of LED backlighting. One is referred to as Edge lighting, and the other is called Full-Array lighting. With the Edge lighting, the series of diodes are arranged along the outside edges of the screen. When there is power, the light is distributed across the screen. Alternatively, in Full-Array lighting, there are several rows of diodes behind the entire surface of the screen. They provide more control over brightness and dimming, because the diodes can be turned on and off independently.



LED TV's are LCD TV's with a new backlight system. They are newly developed for LCD's, because Light Emitting Diodes are said to give more balance in color saturation, and use less power than the fluorescent lamps. LED TV's are the newest version, and that's why they are currently more expensive than the standard LCD TV's.

Summary:

LED TV's are still LCD TV's. They are just considered to be the newer LCD TV version because of the new backlight system used. The LED TV uses Light Emitting Diodes, while the standard LCD TV uses fluorescent lamps. Although they both still use Liquid Crystal Display technology. The main difference is the part behind their screen, which is the backlight.

Remote control slow to respond to Bush tv (LT42M1CFA)


Even though your TV s remote control emits infrared light, it might have not sufficiant frequency as it supposed to be. The fault with its resonator crystal inside the circuit board need replacement. It will look like this. Replace it with exact frequency marked on it.8_16_2012_4_53_50_pm.jpg

The remote won't work. Battery's are good.


Hello
You just check if your remote control hanset emits infrared light. There is an infrared light emitting diode, an LED [Light Emitting Diode], in front of your remote control hanset, from which that rays goes to the infrared sensor inside your TV, which in turn receives it and processes it. You can check its emission. You may have a cellphone with camera option. Set it to camera positon and face your remote controls' LED towards its lens, at a distance of say 1 feet or so, just press all keys one by one and see whether there is light comes from it or not. Your cellphone camera will sense it and you can see its image on its screen. If not, your remote handset is not working. Check its battery contacts for any dirt or rust, that prevents proper battery contacts. If it is Ok, just open it, it is snap fitted and you can open it. Check whether there is any loose solderings on the leg soldering of the above said LED, or a crystal used inside it. If all are ok, you have to replace the remote handset. OK.

Remote will not turn off TV The Charter Cable technicain thought the problem was the LED What do I do?


LED? or the IR sensor?

LED is a light bulb in short terms or a light emitting diode witch has nothing to do with your set all togeather.

First clean off the senor with a dap of alchol, try changing the battery if your using a cable box remote call charter for the correct remote codes for your TV.

I think your technition may have been under the influence or just not educated to tell you the remote codes or just did not want to set this up for you!

Ether way do as i suggested call them and ask them for the remote code booklet if your using the remote control from the cable box to control your tv. You be glad you did.

please leave postive feedback and ratings for your free soltuons today.

Neovo x17a monitor


Are the settings on the video output correct? Is there a green or orange light illuminated. There is a difference between the Power LED and the Signal LED which is green. If you have no signal the LED will remain orange or yellow but not green. If the LED is green, then a signal is getting from the PC but not necessarily good. Check the signal with another monitor or TV if you can. Check the cable.

I just can't get it to work, new batteries and all.


First check if the remote control is sending an infrared signal. If the LED is flashing, this does not mean the Remote control is sending the IR signal. There is a separet Infrared LEd that sends the signal. To check the IR, point the remote control in a video camera or any camera with real-time monitor (phone cam, webcam, etc.) and press any button. You will see a white flash coming from the Remote control. thjis works best if the camera is black&white, for color camera, the IR is still visible but quite faint. Another way of checking the IR (if you do not have a camera) is to press the RM in front of another device with remote control and while doing so, press the correct remote control . If that other does not function or functions erratically, then the remote control in question is emitting an IR signal. If there is no IR coming out, the solder conection of the IR LED might be the problem. It is rare that the IR LED will be damage because the remote control is only 3 volts. If the remote control does emit an IR signal, then the TV remote reciever is defective. I had this problem with a CD player that I have fixed. The IR reciever looks like an LED (dark colored) with three pins (V+, signal, ground). Cost less than $3
