Television and Home Theater

I have a Mitsubishi model 65819 rear projection television.  Recently, the picture has ghostin?, red green etc. outlines around the rimary image.  When I go to the convergence adjustment in the menu, the red green , etc. lines are all out of adjustment and I can't reset them.  Once in awhile, the image returns to normal, but not for very long.  Is it the convergence board(s) going out?  If so, what does this normally cost to repair.  The televsion is not 5 years old yet.

Hello, I noticed the blue was really low in the picture and green dominated. There is also a halo affect. So I cleaned the mirror and lenses and no change. I looked through the blue lense and noticed a yellow solidified liquid with a crator like appearance. I assumed that some moisture had gotton between the lens and CRT so I began to take the 4 screws out of the lens and low and behold oil started leaking out and about a 1/4 tsp. fell on the board below. I found out that this liquid is a coolant used to keep the CRT cool.

I have a DVD player i have connected to my TV and i cant find how to get to the channel to view my DVD anyone who can Help I will be Very Happy Thanks :)
