Hi All

Ok. Jay got done doing a thorough clean of the machine including adding new LEDs. All seems fine when power switch is turned on. Try to add credits via switch on coin chutes and credits do not appear. Put in test mode and flipper switches do not work. Tried to out in tourement mode and can't get to far there as switches don't seem to work. Other than that, when machine is just sitting powered up all seems fine. Was working ok prior to my cleaning and waxing playfield and changing bulbs to LEDs

Please anyone out there would appreciate some help. Hate like hell when shit like this happens

Oh well. I'll get it eventually with your guys good help. Thanks in advance

Hello Viper

Went down and took a look. The status led's are blinking on the aux sound board, sound board, CPU board and Dot Matrix board. Doesn't seem to be one on the driver board. I will look to find the flipper board but again, when I manually trip the switch in the coin chute to add credits, it will not. I did not advise earlier but I also did the ground mod for the game and was exceeding careful here to insure that the grounds were indeed connected.

Does this assist with your assistance to me?

Thank you Viper,

George...

Viper.

I would assume remove p4 with power off and then power on and try switches

Correct?

Thank you

This did not seem to affect anything as far as switches go. No flipper sense when in test mode and still not able to add credits with the coin chute switches

I am grateful for your help. Anything else I can check? Do'in need to test each individual led that is under the playfield? I'm all ears

Thank you

Hi ALl,

Wanted to maybe clarify a bit where I am at with this beast. Attract mode seems to work just fine, Audio, DMD GI lights. All seems just fine. What I cannot do is to get the game to register a credit when I manually trip the coin chute switches (either) and the machine does not want to see the flipper works either. I understand that even in attract mode the flippers should be able to show the instructions for the game on the DMD but it is as though they are not there. Checked what Viper suggested the the board under the playfield is not disconnected. All the status LED's on the individual boards are blinking as they should. I also did as Viper suggested and disconnected P4 from the driver board and check again and this did not prove any different results.

If there is anyone out there that is well versed in GTB Sys 3 and can assist, I'll buy you a beer! OK, I'll send you the money for a beer unless your in my neck of the woods.

Thanks guys,

G

One additional thing I thought might help. In test mode doing the switch test the machine reports all switches open. Doesn't sound right as the trough seiches should show as closed since the balls are sitting in there.

Just sent a pm. Flipper switches are not working. That is a major part if the problem

Thanks

By just pushing the yellow test button inside the coin door area and stepping through some of the tests. Sorry for the confusion. I could not control any if the tests though. Bob has been a huge help on this project. Machine is now running with P4 disconnected on the driver board. Am planning to remove all the LEDs from the controlled lights and just put in 44's. I hate to do this as I spent some good money on those with Cointaker. Wish I knew then what I know now about system 3, controlled lights as using LEDs. DONT. Oh well line and learn. Also found a bad opto circuit at the top if the ski hill

Going to replace the transmit and receive LEDs and that should fix that. As is it is reporting a closed circuit as if a ball were breaking the beam when indeed no ball is present

Also going to replace the three bridge rectifiers as I think I have one going bad. For the price I'll just do all three and w done with it

That's where I am at now. Thanks to Bob and Jim at Echo Lakefor all their kind assistance

Hi There,

When i just powered the game up, all controlled lights were back in order working correctly along with switches but that opto circuit at the top of the slaom hill was still thinking there was a ball up there. One Red LED is on on the opto board so I think I may have a bad transmit or receive or both LED at that location. I will swap it out and see what happens. Thank you though for your post.
