Question about Hitachi 57F500 57" Rear Projection HDTV-Ready Television
When you turn the tv on we have blue and red double vision
the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck

You may be able to correct this problem with the convergence controls in the user menu. Hitachi also has on some projection sets a button called "magic focus" which is an automatic convergence control. If you can't seem to bring things back the way they should be you may have to get your convergence ICs replaced as well as some resistors in the convergence circuit. Unless you have above average soldering skills I'd suggest leaving that up to a technician.

You need to replace both of the convergence IC's and any bad resistors around them that protect them from damaging the power supply.
This repair can usually be done in the home and takes about an hour; I have done hundreds of them and now is a slow time of year for TV shops; look around if you are not able to do this repair; you can buy the chips on Ebay for less than 15 dollars for a pair plus shipping.
This is a very common problem in projection sets.
