Baywatch

[Blktgr74]

Hi guys can anyone tell me how many rom/ chips are on the DMD board in baywatch? I pick one up today and I'm starting to sort out its issues. Thanks

Swinks just bought a Baywatch a month ago. Send him a PM if someone else doesn't advise tonight.

maybe take a photo of the exact board you are talking about and I can compare tomorrow

some resources here as well

thanks. This is all I have on the dmd then for a second you get the full picture I've got 5.01v at the dmd

I will have a look tomorrow night and take some photos for you to compare against (if I remember).

What are the problems you are having? any information may help with trying to assist.


The large dmd's have a power supply problems so at some stage earlier in the release I learnt that the power issue for the dmd's is solved with a new lead that plugs into a more reliable power source. This part is here:

my machine needs this cable and still need to order, if I move my machine / lift the playfield etc it gets particular and the display drops out

Thanks for the help. The problems I have at the moment are
1 dmd isn't working properly
2 I have some gi lighting but only two inserts light up
3 can't add a credit as I can't read the dmd to put it into free play
4 no sound just a hum
Well that's all the cons, on the plus side the playfield is near mint, the cab is good and I swapped an em for it that owed me $200. The boards look good and I can't see any burnt connectors. It's a good project and I'm looking forward to having a game. Any help would be great.

I haven't had mine for long and haven't had time to service it but just been collecting parts for mine.

I reckon the power lead for the dmd is high chance of being the issue and the part is a cheap item, common with the large dmds so i have red. Once you solve that one, you can do tests and determine some other issues.

It is a fun game and a challenge

don't know if any one has answered this but the bay watch display driver board has 2 roms.
and the ones in the photo are in the correct places

thanks that is good news. Now I will have to start looking elsewhere to see if I can sort this out.

[Blktgr74]

Well I've been poking around and I'm still no closer to any fixes. I've changed the ribbon cable and have no blown fueses. Voltages are all good as well. Can anyone suggest somewhere else that I can look. Thanks

if you haven't checked this out try this to assist you in identifying some issues

mentions the gabbled display line and the sound issue ?????

[beaky]

Is the machine actually booting up?
You mentioned only a couple of play field lamps working, are they insert lamps or just G.I?
And if they are insert lamps are they flashing or staying on peremantly ?

[Blktgr74]

It boots up fine with no errors on the LEDs on the board. I have Gi lights and only 2 insert lights that just stay on. I've checked all fuese and reseated all connectors unsure where to look now

[Blktgr74]

Just went and switched it on and everything worked I could add credits and all lights worked then it "flicked" and I'm back to where I started. So I'm happy that it must be an "easy" fix but I still have no idea where to look any help is really appreciated thanks

[swinks]

I still believe some of the issue is the power supply lead from the dmd to the power board, loose or worn out pins in the plug
