You can order a replacement STK393-110 for this model (62HM95) from a major parts distributor at the link below:
Mitsubishi WS-65511 Replacement Part Convergence IC STK393-110
You would probably have to recalibrate the convergence after you install the IC. There may be a convergence kit available as well.

If it is WS-55859 and you go into the customer menu and find red or blue are skewed and will not adjust---you have a convergence problem.
This model uses a single STK-393-110 convergence chip--it and any of the protect resistors around it that are bad will need to be replaced and the set adjusted.
The chip can be purchased on Ebay for about 12 dollars plus shipping--total parts cost should be under 30 dollars!
I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS MODEL.
They tell you everything you will need and how to do the repair---If you or someone you know can do it I can post or get the instructions to you.
If you cannot do it shop around your area--most shops are going to get 300 or MORE for this kind of repair and many will not do in in your home--Any good tech can do it in your home in about 1 hour--I know as I have done hundreds of them.
If you have questions or need help let me know--I am here to help people.

2,2 is short protection.
98% chance the fuse or fuses (there are two 5 amp pico fuses) that protect the convergence circuit are blown. If you find F9AO4 OR F9AO5 on that board check them--if either is open the STK-393-110 DID IT.
Fairly short life for this chip if it was installed correctly and had heat sink compound applied to it--once in a while you get a bad one.
