Good Day! I have a Hitachi Digtial Ultravision, Model 430WX10B. Its color convergence is bad and there does not seem to be a way to adjust it. Is there someway to manually adjust this ourselves or do we have to have someone come out and replace it? If so, what is the charge for this repair, please? Cheers, Trish ~ Trish@CorvelliRealty.com or 703-815-6250 THANK YOU!!
