Hi and welcome to FixYa,

To my knowledge, if the unit referred to is an iLO 2600 TV unit, then a temporary workaround may be applied by increasing the distance of the rear of the unit from the wall. The idea is to improve/increase the ventilation. The best would be to add forced ventilation such as the installation of blower/fans similar to those used in desktop computers.

Identified faults are in the air vents of the unit and that basically the unit runs hot.

Good luck and Thank you for using FixYa. Happy Holidays.

If "The right half has a picture the left has coloured lines.", than that is not a setting problem, that means that the TV has a fault.
If the image is also dimmer than normal, then it is for sure the Sus board that has a blown fuse and must be replaced (fuse indicates board is defective).
If you get vertical band on a portion of the screen this can also be because of one of the ribbon cables that connect to the screen.
This cables have a built in chip technology, and when the chip is fried you get vertical bands starting from where the cable hooks up.
To find out the technician must remove the metal bracket and cable from the connector and read impedance on the resistors located on the cable.
On many models there is also a board called lower buffer , when that goes faulty you also get a verical band , or part of the screen black, or covered in lines, depending on the fault.

regards

    Are they spaced evenly?

    If so, an IC responsible for control of the individual pixels has failed.

    If not - well, I can't think of anything that would cause a random appearance of any color.

The color flashes could be cause by a low 5 volts from the power supply to the video circuit. If you are able to measure voltages using a multimeter, I would suggest to check for proper voltages, specially the 5 volts. If they are low then you have a power supply that might fail completely soon.
If your TV is less then a year old, I would suggest to contact the manufacturers to get fix under warranty.
Let me know if you need further assistance.

    Depending which cables you are using, you should check your cables to see if you have them in the right order. The other issue with some ILO's they run really hot.  Keep the TV away from the wall and allow air flow.  If necessary, you may want to buy computer fans and mount them on top of the vents with air flowing outbound. (Using Coarse Thread Drywall Screws to mount-top two holes only) You will need to buy a universal adapter set to 12V. It will take some rigging with wires. (Red for  positive and black for ground) Test the fans before mounting. The fans run independently. Also, you will need a switch to turn off the fans when TV is not in use.  The problem with some models of ILO's , there are not enough vents for the heat build up. and it leads this problems.  so where ever it's hottest on the back panel, place the exhaust fan there. On bigger screens you may want 2-3 exhaust fans.  It is a $25-30.00 investment but your TV will last a lot longer...years

I hooked up my cable box up to my sceptre tv and it had sounds but the picture is black and white I even went and bought the blue and green cords but still only black and white


With the blue/green/red cords (Component) you need to get a very good bright light on the connectors so you get the plugged into the correct COMPONENT connectors on the TV. Note, there are white and red AUDIO plugs right near the COMPONENT input so you need to be VERY careful. If you get it wrong, the colors on screen are often off and even black&white.

How is your cable box connected to the TV? Screw on "COAXIAL", Yellow, Red, White "RCA", single flat connector "HDMI" or 5 colored plugs 2 X Red, 1 X White, 1 X Blue, 1 X Green "COMPONENT"

OK, here is the breakdown on whet you are doing wrong.

Video 1 - Composite -
Video - Yellow
White - Audio In - Right
Red - Audio in - Left

Video 2 - Components - HD - RGB = Red, Green, Blue
Video -
Red - Red Colors
Green - Green Colors
Blue - Blue Colors
White - Audio In - Right
Red - Audio in - Left

Your GameCube will only work on Video 1, unless you buy an HD (Component cable). You will need to buy HD cables for your device connected to Video 1 to work on video 2. I will assume it is a DVD player. This is a high definition cable to produce a better picture. Let me know if you do not completely understand

When you turn on the TV the screen flashes through a sequence of red, green, blue, white & black screens. Unable to access menu & no sound. TV Model LG 27LC2D


Sounds like it's in a service burn-in mode. LGs need a service remote to de-activate. Probably easy for a local LG shop.

No sound on play back using camcorder on technika tv


Looks like you are using Component cables. There are five cables. The first three cables are Green,Blue and Red. These are the ones that are molded next to each other and are the Video signal cables. The other two cables are Red and White and they are the audio cables.
First to correctly hook up these cables you need to Connect (Match) Color for Color. (Green to Green, Blue to Blue, and Red to Red. To tell if you have correctly connected the Video cables is to look at the screen. If the picture looks ok (Normal with no colors missing then you have connected the video cables correctly). If you see a missing color meaning red, then switch the Red cables. The picture should be ok now. The remaining two cables are the Red and White cables. The "Red cable" is for the "Right" audio input and the "White" cable is for the "Left" audio Input". If all is connected correctly then you should have a good picture and Left and Right audio.
