Re: ultrascan hitachi 43" hd tv

What you're describing is convergence and the amps need to be replaced... IK04 and Ik05 are two STK392-110 and Hitachi suggests replacing them with the STK392-150's for greater reliability..
If you're not too capable in electronics this is one to leave for the professionals. But at least you can call around and ask what each shop charges for replacing the convergence amps in this unit...
Hope this helps.

Yes, it is HD TV ready but you must have a set top box from your cable or dish company that provides a Hi Def signal. The inputs must also be connected with the YRB cable. Only certain channels on my box are HD. The screen is so large that HD isn't nearly as impressive as some of the smaller models but it is still HD. I also have the 53FDX10B.

Free TV

It probably has a broken mirror or somethings inside the set blocking part of the pic. Now for ther picture all red. If your not a tech I highly advise you going insidew this . Unless you know about the saftey issues and the HI voltage issues. Your problem could be a shorted Picture tube all the way to na bad distribution block . Good Luck
