I've been wondering the same thing myself. But then again, if it were just the PC-TV's problem then it would be ok on the Sony Trinitron, but it isn't. I did get it working on the Trinitron by switching several pins around, but since it isn't true RGB21 (it uses an adapter) it's a bit more forgiving. I wonder if it has something to do with the Sync or something. I'd plug it in to my Framemeister, but I don't want to risk damaging it if signals are going to the wrong pins.

What are the pins that you have switched?
1-2, 5-6 and 9-10 or what else?

Like an idiot, I forgot to write down my pin configuration that I had going on the Trinitron. I wrote the original pin numbers on the pins so I wouldn't lose the original pin configuration, but totally forgot to write down my changes before returning to work on the NEC PC-TV. My goal was to make the NEC PC-TV and Hit-Bit into a gaming workstation setup, as opposed to a portable console kind of setup...

I can try changing those suggested pins and see what happens, though. I just keep wondering if something is wrong with the Hit-Bit or if its RGB output is somehow slightly different (maybe with its sync or something.)

Oh my god, thanks! Switching pins 1-2, 5-6, and 9-10 fixed it! I can't understand why, but I'll take it! Any idea if this setup is safe for use on my Framemeister?

It's simple: Scart (or RGB21) cables should NOT be straight wired. The outputs from the player (computer) should go into the inputs of the monitor and vice-versa, so switching audio (1,2 & 5,6) and Video (9,10) wires did the trick.

Hi michellybells, 2 questions:

  1. What is the serial number of your HB-F500?
  2. Would you consider creating a dump of the ROMs and RAM of the computer with SAVEROM.COM? If so please dump slots 0, 3-1 and 3-2 (you can use start address 0 and end address ffff).

Thanks in advance!

Unless you know the machine by its serial number there's not a lot you can do with Sony's serial numbers. They're scattered allover their products.

Well surely they are incremental. My F500 has serial 205158 michellybells’ should be higher, if I want a V2 F500 I can look for higher than that...

Check Sony's entries here. They make it seem that every product that came from the assembly line got the next free number in the house.

@Meits but this still does mean that the one produced later gets the higher number, right? I see no problem here to assume that if you got higher number then you have a product which was produced later... even if they use one serial for all the products
