    Hello Everyone.

    I have just installed a customers Hitachi 7500 and have encountered the following unusual problems.

    1. The unit sometimes forgets its FREEVIEW set-up data, and asks to be retuned. This is only on FREEVIEW and does not affect Analog TV? I happened once durring set up, and other people have repoted this on the forum.

    2. The component input produces a split in half (vertical) rolling picture. I checked cables and DVD player( Denon2800II) settings. But nothing could sort this problem.

    3 Using a JS Technology (scart) RGB > VGA converter into AV3 PC RGB displayed a distorted and frozen picture. The Hitachi claims to accept every input signal under the sun. But the JS Tech does not work. Again, all leads double checked and swoped.

    Any help and advice woul be helpful.

    Best regards

    No Hitachi works with any sync separator I'm afraid. They need a minimum horizontal sync frequency of 32Khz from memory, where scart, even via JS, is 15.625. I have heard of previous denons not being too hot with Hitachis too. I'm well known round here for being anti Hitachi. They may be fine for a TV, connect a all in one from dixons on scart, but it ain't a custom install product. You've just found out why.

    Thanks for the info MAW.

    This is the first 7500 I have installed, I thought it was me!

    I will let the customer know.

    Guess I will see if he can change it for a Pioneer 436!
