Hello. I have a burnt component on my mpu board... Are this a normal issue on the IGT S+ 10 mhz mpu board?

The Q5 and Q6 (see picture) on my mpu board have melted on the component's. How can i fix it ? Do i have to order a new mpu board 10 mhz to my s+?

Did your machine have a problem that caused this mpu board failure? Be careful about installing a new mpu, same thing could happen to it if the problem in the machine is not corrected.

Q5 and Q6 may be parts that are connected to some of the player pushbutton lamps. Have you had a problem with the pushbuttons or button lamps, have you done any work in that area, replaced any button lamps or is the wiring to the pushbuttons damaged, pinched? This wiring would run from the machine cabinet to the inside of the door, there is an opportunity for these wires to get damaged and short.

The white test Button have been changed becaus this Button dont works anymore. So this can be the issue of the problem i have on the board? What are you thinking about that?

Would need the drawing/schematic for the mpu board to know what Q5 and Q6 are connected to in the machine. I don't know the history of the machine, if you are aware of any work to it or any defects then you should take a good look into that.

Before I'd install another mpu board I'd check wiring and other things to make nothing is shorting out to the metal chassis. And try to find out what Q5 and Q6 get connected to, that is where you have a possible problem. These parts didn't just burn up on their own, most likely something not on the mpu board caused them to burn up. I don't think the TEST button would connect to Q5 or Q6 so that probably isn't the problem, unless when replacing the TEST button nearby wiring was damaged. If pushbutton lamps were changed I'd make sure they are the right type.

Did these parts burn up AFTER the test button was replaced? What other information do you have?

I dont know. This self test Button part have a 3 solder points. I solder this new part like the old one

You need to give people a chance to answer your questions.. Remember that some people don't log on till evening or just once a day.. Your board looks like it could be repaired since everything seems to be there. No burnt traces or holes burnt thru the board.. Make sure that if your machine has fans that they work..

Cashen87 · « **Reply #10 on:** June 29, 2017, 11:33:35 AM »

I know that. I post this topic some another on the forum can see it... it was a question...

Cashen87 · « **Reply #11 on:** June 30, 2017, 07:10:50 AM »

Its this a normal issue the Q5 or Q6 component get burned/ melted?

rokgpsman · « **Reply #12 on:** June 30, 2017, 07:53:22 AM »

Not a normal routine failure from what I have read, but others here with more experience may have a better insight. When components like Q5 & Q6 burn up like that it is due to excessive electrical current flowing thru them, that would be caused by something they are connected to either being shorted or for some reason drawing too much current. That's why I cautioned about installing another mpu board without first trying to find out what caused this mpu board failure.

What is the history on this machine, have you had it for a while and all was working ok until this happened? Or did you just get the machine and do not know if it has other problems? What work has been done to it, something that could have caused this failure? As I said earlier I think it would be good to know what in the machine is connected to these burned mpu parts, that would be the area to take a close look at.

I have never had a problem on this machine before I change the white test button... I have see on this forum a another person had the same issue on his board to...

rokgpsman · « **Reply #14 on:** June 30, 2017, 08:04:06 AM »

What did that other person determine was the problem that caused it?
Can you post the link to that discussion thread?

Cashen87 · « **Reply #15 on:** June 30, 2017, 08:50:50 AM »

Good question...I don't remember

rokgpsman · « **Reply #16 on:** June 30, 2017, 09:33:54 AM »

How did you find it - some kind of search, or just reading thru the old posts?

Cashen87 · « **Reply #17 on:** June 30, 2017, 09:40:25 AM »

Yes. I'am Reading true the old post...

Here are the link I found about the same issue I have on the burned connector on Q-5 and Q-6. http://newlifegames.com/nlg/index.php?topic=14693.0

Thanks for that link, I and others were involved in that discussion. It involved someone that changed the bulbs in some of the pushbuttons. If you use the wrong style of LED (or other bulb) then you can short out the connection and burn up the parts on the mpu board that control the bulb on and off.

Do you know if the bulbs in your machine pushbuttons are the original and correct type? Might want to remove the bulbs and check the part number written on them.
