Title: Game of Thrones LE Flippers intermittently quit
Post by: randyman on October 17, 2020, 02:43:16 PM
I've got a GOT LE that just started acting up.  Basically when multiball is in play (sometimes just a single ball), the left and right flippers (upper and lower) just lose power to them.  I've replaced the front flashers (LED only) and checked the connections on the opto trough board.  Other flashers check good on bulb test.
Any other ideas?

A strange one & not sure why you refer to your flashers, are they in the same line as the flippers?  Do you only lose power when flashers are on? 

Possibly a loose connector in the backbox?

it sounds like a loose connector.  if u think it is the flasher the n remove the flasher and see if it works.  btw did u use  12volt flasher?

Sounds like a loose connector.  My Avengers drop targets acted up in a similar manor and unplugged the connector and reconnected, it works great now. Same issue on ACDC this past weekend, right sling shot worked on and off, loose connector. 
Good luck and keep us posted.

This is impacting the flippers only and typically when there is high action.

- Adjusted power supply to 48V, no change
- Disconnected aftermarket sub, no change
- Disconnected aftermarket Shaker, no change

I'm down to Node 8 or the power supply itself and will report back when I figure it out.

Provided you don't find a loose connector sounds to me like note 8 is in overcurrent especially if it's high coil action when it happens, and if that's true and the power supply was adjusted UP towards 48 volts the problem is probably worse as with an increase in voltage you will increase the amperage as the resistance of the coil remains unchanged, I'm willing to bet there's an LED light on the node board for an overcurrent situation I'm wondering if you can stick your phone in the bottom of the cabinet on video pointed towards the node board and vigorously hit the flippers until they stop maybe you can capture an led light coming on the node board. I think node 8 and node 9 are the same, you can check in the manual if they have the same part number, so you can readress them on the dip switches and switch the boards but I would try that last. Furthermore if you switch the note boards and it's still happening my gases you have most likely an intermittent short to ground on the upper flippers that would be the first place I looked

i have had a lot of strange issues with games when the wrong voltage of bulb is installed. i dont think the spike systems use 12 volt flashers.  if you have a 12 volt flasher installed i would remove them and see if  you have flipper issues.

aren't the "flashers" actually 6v on the slings? Been a while since one of mine fell out.

Node 8 and 11 have the same part number according to the manual and may be swappable. Plus it's says flashers and regular lighting is all the same voltage, I know comet supplies them gi therefore I'd assume the flasher need tobe 6v, I'm with busa, removing whatever flashers you swapped out as you may have inadvertently used the wrong voltage ones in those socket crating an overcurrent situation.

EDIT: I didn't realize schematics were actually posted for spike to sterns site, they are by node board. I just looked at node 8 and Led voltage for ALL bulbs is 6v. Check your flashers as busa suggested

yes 6v flashers.

Not a lot of flashers in this game.

235  Sword Lock
236  Right Ramp
237  Pop Bumpers
242  Left Loop
243  Battering Ram
244  Left/Right Sling
245  Throne

yes 6v flashers.

Actually, 5V

Schematic says 6! Lol

Yep.. part number lookups show 5V so it's nice and confusing.

Blackwater multiball flashes those slingshot flashers like crazy he also said it happens in single ball play sometimes, I would assume this is during a winter is coming if this little flasher theory pans out, randy man start up a winter is coming hurry up by shooting the white blueish shots until it activates and report back about your flippers during that mode, just a thought

I tested this previously and it eventually happened, but not as quickly as the other multi ball.

This sounds eerily like when the late SAM era games started having this issue due to the  connector on the trough jam opto and Stern switched to the Molex style connector to remedy the problem.

OP, please clarify if, when the flippers go dead, the ball in play ends?

I thought this was the case and had OP replace the trough opto receiver board before I went to take a look. I was able to confirm while on site that the turn does not end.

at this point i would remove the new flashers. It was the last thing the OP said was done before the flipper issue.  No one has mentioned if they have or have not done this step.

I spoke with him and he did not replace the flashers, but the first post does, just removed the existing to test and the issue persisted. I'm going to stop by in the morning and run through some additional tests.

Both slingshot flashers are plugged into the same node board that runs the flippers, so that's my first stop.

Swapped Node 8 with Node 11 and the game is happy. It looks like Node 8 can't handle the demand of all the large coils and is doing alright as the new Node 11. It will probably need to be replaced at some point, but we beat on the game pretty good today and it helped up nicely.
