The experts at Cello Electronics have a vast amount of knowledge and experience that is concentrated on continuing to produce the best quality products for its customers.

This is why it offers a comprehensive technical support facility to all its customers, which guarantees, in the unlikely event of a problem with their Cello LCD TV, that they will benefit from a professional repair service.
Why does Cello only sell LCD TVs?

This is so that it can ensure the LCD TVs that it sells are the best you can buy and by focusing all its efforts on continually developing and growing the levels of technology used within the LCD TVs it manufactures, Cello products are of a higher standard and quality than those produced by its rivals.
Can my LCD TV wall mounted?
The majority of Cello TV’s are wall mountable. On the rear of the TV there will be holes where the wall mounting bracket can be fitted. If you require advice how to remove the stand it is advised to speak with our service department or simply send them an email:
service@contrast-uk.net.
Can the TV be used as a computer monitor?
The majority of Cello LCD TV’s have the facility of connecting as a monitor via the VGA socket, however it is best to check the specifications of each model. Connecting to a laptop is a different matter though due to laptops being configured to use their own screen. As every laptop is different it is recommended that the consumer seeks advice from a Computer Specialist before connection.
Can the TV work on 12 volt supply?
All Cello televisions are designed to use the power cables that are supplied with them. Even though a selected few models are supplied with an external power adaptor which do convert 240 – 12 volts it is always advised to use this adaptor in its appropriate manner. If a TV were to be connected directly to a 12 volt source incorrectly (Battery source) it is possible to damage the television which will inevitably void the warranty.
How do I get the best TV signal?
To view channels correctly, a signal must be received by the set from one of the following sources:
- An outdoor aerial (May need to check the digital service in your region.)
- A cable television network.
Cello Electronics recommend the use of an outdoor Aerial suitable for receiving digital television transmissions. The use of an indoor or portable aerial is most likely to result in loss of full digital service as the quality of the digital signal may be impaired. It is advisable to consult a professional aerial installer if in doubt.
I have lost sound on a small number of channels on Freeview
If you imagine the signal on digital to be as computer data which the TV needs to read and produce the pictures and sound. Like any computer if this information is not complete or distorted then the outcome will not be correct, a good example of this is where one or two channels have no sound but all others working fine. It is advised to ensure your aerial installation is of an outdoor type and whether full digital reception is available in your location before attempting to re-tune the digital channels. If assistance is required please contact our service helpline: 0845 519 2367
I’ve got black bars on the sides of my screen
Your widescreen TV produce picture in a 16:9 format by default but your TV may have been set to the 4:3 format in error. On most models there may be an Aspect button on the remote control that will change the picture size. However, on others it may be required to go in to the menu to change this, if you require assistance please contact our service department and they will be happy to help.
Important 1: If your TV is attached to external devices such as set-top box, you may be able to eliminate the bars by changing the output resolution of the external device.
Important 2: In many cases, the cable or over-the-air TV Company is broadcasting the program or movie you are watching in the format that includes the bars. If this is the case, you cannot eliminate them.
Important 3: If the video or DVD you are watching is being broadcast in standard 4:3 format, changing the picture size may distort the image or cut off part of the image. If this is the case you may want to leave the picture size at 4:3.
Is my TV HD ready?
The majority of the TV’s are HD ready via a HDMI socket on the rear of the TV which enables connection of external HD devices. It is advised to check the specifications before purchasing.
My TV is slow at changing channels
One of the noticeable differences from analogue signal to digital is the way that the channels and on screen display (menu features) appear with a slight delay. This is quite normal due to way that this digital signal is being transmitted and received by the TV. The easiest way to explain this is to think of the digital signal as computer data and your TV has to read this data before converting this back to pictures and sound.
Should I choose an LCD TV or Plasma TV?
This is a much debated topic and a fun one. When choosing between plasma and LCD TVs, you're actually selecting between two competing technologies, both of which achieve similar features (i.e. bright crystal-clear images, super colour-filled pictures) and come in similar packages (i.e. 3.5 inch depth flat screen casing). To complicate the decision-making process further, price and size are two previous considerations that are rapidly becoming non-issues as LCD TVs are now being made in larger sizes and at competing prices with plasma.
The Picture is Pixelating
Pixelation of the picture often is caused by poor signal quality. To ensure your digital signal quality is of the best you need to ensure you are using an outdoor aerial suitable to receive digital television signals. You may require an aerial upgrade but we advise that you consult with a professional aerial contractor who will know reception levels in your location.
The TV stays on standby when I turn it off. How do I turn the TV off completely?
Some of the earlier TV’s (model list 1) use an external power adaptor in this case the TV does not come equipped with a power off function, the only way to turn the TV off is by the switch at the mains socket.
Green button feature: Some models (model list 2) have this facility where there is 2 buttons on the
remote control:
- Standby button which simply turns the TV in & out of standby.
- Green power saving button which turns the TV power off completely. On
the TV there is a special switch that brings the TV back in to standby
after it has been turned off using the Green power saving button.
What are the pros and cons of an LCD TV?
PROS
Direct-view models are only a few inches deep.
Desktop space-saver
Good picture quality
Environmentally friendly
15" flat panel gives you the same viewable screen as a 17" CRT monitor
CONS
Of all the fixed-pixel technologies, LCD has the biggest problem producing true blacks. Some light always passes through when the liquid crystals untwist, so the best black on most LCD panels is a very dark gray.
Because of the way light passes through an LCD cell, direct-view LCDs usually have a narrower viewing angle than plasma TVs.
Low-resolution LCDs exhibit distinct pixilation and screen-door effects when blown up to big screen sizes. For front projection, using a model with XGA (1,024 x 768) or higher resolution will reduce screen-door effects.
What is Cello’s policy on TV dead pixels?
All Cello TV’s adhere to a stringent standard regarding picture quality.
LCD screens are made up of over nine million pixels and in very rare cases it may be possible to notice pixels which do not perform perfectly. Due to this common phenomena Cello use the following criteria to establish warranty replacement.
