Question about Hitachi 53FDX20B 53" Rear Projection Television
Convergence output Ic's and check associated low ohm resisters, replace any that are open.

It's a hardware malfunction. It can't finish the magic focus cuz one of the IC is burned. Need to be replaced and to check the resistors.

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.
