Quoted from Taxman:You should replace the header pins on the board as well at the connector. Yes it is a PITA but there is a bigger problem. The build up of residue from the burning acts as insulation on both sides. This means increased resistance and therefore more draw of current. The old Ohms law thing where the increased resistance and in Power in the form of heat.
Excellent explanation. I ordered a new header pin and connector from Marco. Thank you.
Quoted from xTheBlackKnightx:If you keep turning on the machine and running it, you risk more problems with the PCB. Replace the pins and connector ASAP. If you burn through the pin insulation plastic you will have burnt traces, more repairs, and more woes.
I agree. I disconnected GI connector from PCB to avoid any other problems.
Quoted from mikat11:Use LEDS in the GI and that will never happen again.
My next step! 101% Led!
May I found the real problem... but I don't know how I gonna fix yet..

I disconnected and connect the plugs ... the yellow cables are "cold" now.. but the another cables continues to get hot.
Quoted from jwilson:Well, a lot of current is running through them - each lamp uses .25A of power. Those connectors are 20 years old at least, they probably could use a good cleaning.
I bought a contact cleaner today. Now, all system is cold again. Thank you.
I've a "never touched" Sega goldeneye... For the very first time I'll replace 2 connectors and 1 transistor (blow today.... Q42 - 19N06L) It's ok for 20 years of use.
Quoted from vid1900:You **could** have a bad LED or lamp socket that is partially shorting out.
You **need** to replace both the male and female connectors of that burnt one.
You **need** to check that the the GI fuses are the correct value, and not larger than specified.
Sockets: Ok !
Fuses: Ok ! 5v
Male and Female connectors: I ordered on Marco... Will take almost 1 month to arrive in Brazil
PS: your playfield restauration guide are amazing ! Thanks.
