Hello.
Blue screen usally means no signal.
This sounds like a cable/cord cennection problem.
If you are using a scart cable between the tv and the cable box
make sure the contacts are firmly inserted all the way,
Sometimes scart contacts are hard to get all the way in.
Howerver if you are receiving the CATV channels the sdame way as the rest of the channels, through an RF cord (antenna cable)
there could be a problem with your supplier of these channels
Best of Luck

Im sorry to hear that the problem is beyond the "easy fix" stage.
I gather you are using a 3 split AV cable (red, white and yellow) which only works in "Composite mode" however if you are using a scart cable you should have 2 catv modes in which it should work..Compisite mode and also RGB mode,,, have you tried both ?
If you cant switch over to these modes on the remote aswell as on the TV direct then im afraid next step would be to have a repair man have a look at some service shop since you are right that it would be probably be the channel or input circuitry inside the TV that is broken.
Also you can leave the question open here..someone might have a better answer for you.
Thank you.

I get what your saying, but when I put a different tv on the same cable and plug it in, it works just fine. could it be a problem inside the tv? Or is there a possible simple solution that I could try before I have to go spend money to have it looked at?
