Pioneer Elite Pro-510 input problems

[mzo0163]

the component inputs on this tv seem to have gone bad. One of the component colors keeps going out on the tv so the images are red or green mostly. When I put pressure on the individual cables at the base of the connection the picture is fixed but then will go back shortly after. This only happens with the component inputs and not the others. Ive swapped the cables/DVD player and still the same problem so it has to be the TV. Does anyone know how serious of a problem this might be and how costly it may be to fix? Any info would be great, thanks.
