I've had several LED bulbs start to smoke and burn out. They don't burn out in test mode. They are burning out in game play. I used all non ghosting led's under the playfield and reg led's for all the gi lighting. I know on one of the non ghosting bulbs that keeps getting to hot that if I put a ghosting led in it it will not burn up. I'm using some of Pinball Life's & Comet led's. I'm wondering if JP you can't use the non ghosting bulbs? Also I checked if all the bulbs that are burning out are in the same column or row and they aren't they are all over the Matrix. A lot of the led's I'm using are Pinball Life's older flat top non ghosting led's but I'm also mixing in some of the newer ones Terry sells the non ghosting with the dome top and some of the comet non ghosting with the dome top which look just like the Pinball Life bulbs. Do you have any ideas for me to check? By the way the game had just old iridescent bulbs in it before I started working on it. They weren't burning out like this. Any info would be greatly appreciated.
