On my KISS Pro, regarding the "K", "I", "S","S" targets on the lower left, I noticed recently that the first three letters, "K","I","S", always seemed to be on during game play. The final “S” letter just needed a strike and the bonus was rewarded, but the first three letters remained lit throughout the game.

When I turned off the machine and restarted it, the “KISS” target LEDs behave normally in attract mode, all off, all on, light in sequence, etc. The targets are not lit after pressing start, but as soon as the ball is launched and activates the first roll-over switch out of the shooter lane, the first three letters light and remain lit throughout the game.

I reloaded factory code… wasn’t it. Still acting the same. Any thoughts as to what it might be? Is this a failed node board people reference?

Just did a "Factory Reset"... Whew! Everything works. back to normal.

I reloaded the Factory Code first, thinking that would do it. It didn't. The next day, per suggestion, I found the Factory Reset in the menu and did it. It took a whole of 2 secs and it was back to normal. I wish I had I done that first... The Code reset takes about 30 minutes...

My KISS Pro failed last night. Won't boot up. Could be Node 8 (Flippers) causing problem with Node 0. Could be a problem on main (Node 0) causing problem at flippers. Could be SD card... I'll call Chas in the morning...
Anyone have something similar? Any thoughts?

Genius! Was emailing Stern tech support and thought I better check Pinside. Unplugged the Cat 5 cable... same issues. Unplugged all connectors to Node 8... Game boots up. Scores and settings are there. Looks like I need an new Node 8. Thank you again.

I assume you will play the crap out of it. That's what my family did... well they did because it was new and exciting. I did it to see if something was gonna fail before the official warranty was up (picked up in Mid-Feb 2016). Just checked my audits... says 143 total plays. Don't know if that included games before I loaded new code with Pinball Browser, then reloaded original code when a couple issues started. Good luck! I want the Spike system to succeed. Otherwise GB might have to wait!

Agreed! Should have clarified. Contacted my distributor first... he put me in touch with Stern Tech and asked them to help and get me what I needed. Everyone has been very helpful, polite and easy to deal with... contrary to some others unusual horror stories.

Got a new Node 8 board today from Stern. Installed it and game booted right back up. Played it hard... banged on the flippers. First noticed the lower GI bulbs had a slight flicker with each pulse. This increased as play continued until one of my original problems...

Right flipper-dead, left flipper in spasm-then drops dead, lower GI (2 bulbs under each sling, 2 on each side in front of the apron) all go out for a second. Then game returns to normal. Power loss became more frequent with continued game play and flipper use. Finally, game cut out and won't boot past the Stern logo. Similar to previous video I posted.

For those with Node 8 failures, was is just a Node 8 failure or did you find a different cause forcing Node 8 to fail?

Stern tech thinking its a coil issue causing a Node 8 failure. Proper coil resistance measured on all coils connected to Node 8. Coils test OK in Diagnostics menu. Same thing started happening during game play. After flips, lower GI would flicker then finally turn off and flippers dead. A second later it would everything returns. Unplugged left flipper (CN 5).

Played many games with just right flip and glass off to keep activating auto plunge. Wanted to see if problem would return (rule out trough, auto plunge and right flip... nothing... looked like it isolated to left flipper. Plugged left flip back in and left flipped during game play. Got the lower GI and flips to go out. After this though, the right flipper was now able to cause the issue... maybe the left coil stressed the board?

I think I'll change left flipper coil for sure. Hard to belive with such a new game. Anyone have a flipper coil fail on a new spike game? How did you isolate it to determine that coil?
