This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem. If you want to repair this concern yourself: Contact:B&D ENTERPRISES, 1-800-458-6053, www.bdent.com and ask for KIT10 for your Hitachi TV. If you want some else to do the repair for you call an Authorized Service Center.

if magic focus will not correct convergence problem look in the customer menu for the word CONVERGENCE---IF BLUE WILL NOT ADJUST IN some direction, one of the two Stk-392-110(or 392-150) convergence Ic chips are bad; you may also find some burnt or discolored resistors behind them----this kind of problem is usually fixable right in your home; if you need direct help;;;
If this was helpful I would appreciate a vote from you here.
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. http://servicemanuals.vstore.ca/
