Strange rainbow.reenish type effect

Did you notice any better picture when you play a movie on a DVD player or using a flashdrive on this TV? Is the picture quality better? Or is it the same? Try to check another cable connection or try to play TV channel thru internet. The last option in this case is to show a TV mechanic for he would better understand which part to order.

Accidentally hit screen now it has a rainbow line down the middle would it be possible to fix?

Probably not. It sounds like the panel(screen) may have cracked inside. It happens all the time. Unfortunately, it will cost as much, if not more than the tv is worth to replace the panel.

Tv rainbow in screen

The picture tube has become magnetized, possibly by someone getting a magnet to close to it. You can de-magnetize it using a strong magnet (cow magnet or similar). Place the magnet as close the the screen as possible without touching it to the screen. Starting at the middle of the screen and slowly (not too slow, about one full circle per second should do) move the magnet in a circular motion. With each full circle move the magent twards the outside (making a larger circle) as well as moving it farther away from the screen. Using a magnet will not harm the screen, so play with it and you'll soon get the feel and will see what you need to do.
Tv's have a circuit built in to 'Degauss' (demagnetize) the screen each time you turn it on, but this will only work if the set is 'Cold'. If the set is left off for 2 hours (to cool doen) and does not demagnetize when you turn it on the circuit is faulty.

You Have a convergence problem or Pincussion issue with your set. No quick fix for this one. You need to call in a pro to assist you with this repair. Good Luck
