hitachiserviceusa.com I believe.
You'll need a user and pass to get in. Just apply, they send you an email. If this is a newer set they got a cursor based adjustment procedure. There is a hidden button in front that activates the adjustment mode, when you hit it it displays a nice fine crosshatch. Bear in mind the set must be displaying a "kosher" NTSC interlaced signal, such as what you get from a TV station. A VCR output is not acceptable due to time base errors. This stuff is usually frequency sensitive. There may be a twop pronged plug on the PCB to your left as you look into the front of the set. If uand only if/u there is no hidden button, this will be the point to short. Be careful, wait a bit, someone may post how to save your changes, I don't recall right now. It might be automatic, but there is a recalculate function you are supposed to do. JURB |

Sorry, I'd have caught that if I was more familiar with Hitachi model numbers.
I'm not sure exactly which model the EX is, but if it is old enough to have pots it is old enough to need a bunch of electrolytics on the waveshaping board. __________________________________________________ _________NOW, it comes back to me ! You will find that most or all of certain values of caps will be bad or marginal. Once you get a few of the same, replacem all, do the same with the rest of the caps. If it's the set I think it is, there's only two plugs to that front convergenge board. Take it out and get up on the bench. You need an ESR tester of some type, or something. If nobody has cranked the adjustments, they will be pretty close after replacing all the caps. Exceptions might be V height & linearity, side pin, bow and skew. I'll see if I can find the layout. JURB (it might be on a sticker in the cabinet also ) |

Thanks JURB..
Yes its got a few years on it. The pots are just behind the front panel BUT they are not marked as to there functions its a guessing game . I remember the older Mits had a procedure like adjust Number 1 pot then Number 6 pot etc etc. Thanks again kip -- "Watch the return E-Mail addy its false" "JURB6006" wrote in message ... hitachiserviceusa.com I believe.
