White Water - Lamp issues - PLENTY of em !!

[Wotto]

Hey again,

Ok I have a heap of lamp issues on my White Water.

Before reading this , be aware I have replaced all the globes in these area's and it isnt a globe issue.
I appear to have a 'ROW' issue and some other dodgy things going on.

I have scanned a copy of my Lamp Matrix and marked in different colours what the issues are.

Basically I have  a number of lamps out , most are in Row 1, but I also have a couple of other spots that are out that are NOT in Row 1  ( Raft 3, Boulder5X and Start Button ).These problems are marked with Orange and Green dots in my attached image.

Another issue I have ( marked in pink dots on my attached image ) is that Lamp 82 ( Advance Raft ) comes on WITH each of the lamps also dotted in pink ( they dont ALL come on together , they each come on WITH Lamp 82- in pairs )

I hope this makes some sense.



The other issue is that ALL of my GI appears to be out apart from 1 single globe near the whirlpool and the GI lamps under the Lost Mine Mountain Boulder - I have NO GI at all other than those - makes for very dark gameplay.

Thanks in advance.

Start with your favorite part of the machine - the connectors !

IDC connectors are crap and this will most likely be your problem. Push in the Red/Brown wire J133 Pin1 -

Then grab the old MM and set to "Continuity" - and buzz out J133 Pin1 to the Red/Brown wire on each of the lamps.. There could be a broken wire.

Q90 could be an issue here, but it was all working fine before you stripped the playfield

Also look for any shorts from other parts under the playfield to any of the lamps or their holders.

Do the same for the j133 Pin 2 Red / Black.. Follow the wires to the respective lamps in that row..

Following on from Nino's comments above, grab hold of the lamp matrix connector(s) during gameplay/gameover mode, and give them a wiggle, you'll even see the arc'ing sparks within the connector to tell you exactly which column/row has a dodgy contact. (assuming it's not a driver transistor issue).

I've seen this a LOT in many old pins, it's now become one of the 1st things i do when i find a pin with a dodgy lamp/switch matrix....

Hope this helps too.
MM.

Update.............

OK thanks all - it was mainly the wires on connector J133.
Nearly all the non-working globes are good now apart from Start button and Raft 6 - I am sure I can sort those now.


Now- all I need is to sort the GI issue as that is pretty much all still out.
Any ideas for that?
I cant see any broken wires.

GI - Could be as simple as a fuse - There will be a informational card in the backbox denoting the GI fuses. Check them all.

So – tell me.

These games use 5 fuses for the GI ???
It appears that 5 x 5A Slo Blo’s are required for the GI ??

So – if ONE of the 5 is out , then 95% of the GI could be out ??

Each GI string is seperately fused ie lower playfield,left playfield etc. Check for 6 volts at header pins J120, J121 and isolate fault to wiring or PCB. Check connectors as most are burnt out. PM me if you need further help.

They may look "good" but they could still be fried. Remove one end of the fuse and check with a MM set to "continuity"..Now lets see how many fuses are good !

The other thing to check which Dave mentioned - connectors - Do they look healthy ? Refit them.

Also check under the playfield for loose wires on the GI lines. You can tell that they are GI pretty easy as they are all connected via braid.

Thanks guys - will check all that tonight

Yep, definately pull the fuse OUT of it's clip (or at least 1 end of it), otherwise you're measuring the transformer winding and the lamp filament which will appear to look like a 'good' fuse.

That catches everyone sooner or later

GI - Sorted !!

Thanks all for your help and also the private emailers.

I have no idea how I missed this the first few times around 
It was one tab on one globe holder shorting against the other side.
( basic stuff I know - but I aint too savvy with the electronics )

Pushed it back, replaced the fuse that kept blowing and here is the result

Nice looking pin, Wotto - Glad to see it working... 

now it can sit next to the Fishtales and you can ENJOY the pinballs while waiting for your next machine !!
