Hitachi 57'' rear projection tv has double images on both sides.

You have bad convergence. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the problem, how to fix it and where to get the parts. Let me know if you need more help.

Thanks for using FixYa and for the generous rating.

your convergence circuits have failed

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.

Just to clarify, it sounds like what you are saying is that the image appears to duplicate in either red or blue along the edges of the image (especially white lettering and probably increasing along the boarder of the TV). This is resolved by converging your TV. Convergence will drift normally on large screen projection TV's over time or through moving them. The Hitachi 57f500a has a feature called "Magic Focus" (pg 36 in your manual) which will auto converge the image. If the auto converge feature doesn't work, on page 37 in your manual, it explains how to converge manually. If you do not have the manual, I have the image of the pages below. If for some reason this doesn't work, please provide additional info and detailed prior to rating the help.

Your convergence chips are bad. You can set a repair kit from www.TvRepairKits.com for your model. Their kits come with all the parts and a complete photo instruction guide.

First try going into the customer menu of the TV. Look for the convergence alignment parameter and see if you can move the images back into place.

If you can't move the images back together, this is a failure of the convergence circuit in the TV. The convergence output ICs will need replacement and the TV should then be re-aligned. Look for a service center that is factory authorized. Expect to spend $350-$500 to have this issue resolved.

Does the magic focus work on your set ?

If it doesn't you must replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

Problem seems in convergence out section.

TV needs Convergence Out ICs replacement.

If you have TV repair experience and know good soldering work then you can give it try OR get help of qualified TV tech to fix it.

If you need further help, let me know.

You have 2 IC's in the convergence circuit and possibly a micro fuse that needs to be replaced. Consult a local TV repair shop.
