My son just picked up a Williams Pharaoh. The background sounds work, but he is getting no speech. Do the speech rooms go bad often? What should we look at first? Thanks

Manual is here if you don’t have one.

Learn how to get into test mode, there is a series for sound and voice. Go through the test before you do anything else.

Disconnect and reconnect all the wires and cables between the sound board and the driver and power boards. Make sure you do both ends. Do them one at a time and make sure the connections look ok, not corroded or burnt. Pay close attention to the ribbon cable between the sound and voice boards. Reseat them solidly.

There is also a potentiometer on the Voice board move it around And set it at 1/2 way.

Run your sound test again. Let us know the results.

Thanks for the pdf. BK Just tried everything you mentioned, and during the test I only get sounds and no speech at all. Thanks

Please post a pic of your voice board.

Next step would be to grab a logic probe and start digging into the board itself. I don't think the roms would be a primary suspect, but I'm not a board expert.

Yep, missing those three little roms.

Easy and cheap fix thank goodness. Update us when you get them installed.

The speech board should be fully populated with ROMs - you need four! I would burn a set of four correct ROMs and install them. Then check and see where you are at.

I do have all four speech ROMs, the picture was taken during inspection of the ROMs. If my ROMs are any good, who knows.

also the sound rom must match the speech roms. ie it must be a pharaoh sound rom.

This is one thing I haven't checked. Only one of the four ROMs was labeled Pharaoh. The other three, nothing. Would I get any speech at all with only one rom installed at a time?

Does your black knight work correctly?
You could take some photos so you don’t put them in the wrong spot, but I would try those pharaoh roms in the bk speech board , in the pharaoh. Easy swap.
I would think that help determine if it’s the ph speech board or the roms.. ?

That's what my son was thinking, but I'm a little apprehensive about messing with a machine that works fine. Might open a can of worms, with my luck.
