The fault can be on the convergence board, or in the HV multiplier.

SOURCE: the red projection tube won't focus

Set needs convergence ic's changed and possibly a few small 1/4 watt resistors. Parts have to be desoldered/soldered into circuit board and test equip.(ohm/ volt meter) is required. Most repair shops do this repair for 175.00-375.00 Hope this was helpful. Russmann

Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205

SOURCE: images have red and green outlines on them picture somewhat fuzzy

your convergence ic's are Shorted

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

SOURCE: Hitachi Projection TV 57F500A red looks double.

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.

You need to replace the STK ICs which are Convergence ICs STK392-110 use 120s or 150s
also check the small ohm resistors around ICs . They are Big Black ICs and will have part number on them ,should be located on the Right hand side of Chassis .

Will not show red color in picture, magic focus shows red though


You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.

Out of focus


Rach, if it doesn`t move from green to red to blue in Magic Focus then there is a problem with the convergence IC`s and probably one or more support resisters. These components will have to be replaced, questions? ask away, BMW Rider
