Just picked up this family guy and when I turn it on it seems to be stuck in the boot mode. The speakers click and it sounds like it's trying to boot but won't kick over. Any ideas

It looks like when the speakers "pop" the 5v led goes on and off at the same time on the circuit board in the picture

On second glance it is the L18 LED

Reseed all the ribbon cables.

I reseated everything and it seems to be an issue with the upper playfield I got into test and all the upper playfield switches where throwing errors so I disabled it and was able to play a game. Any thoughts on how to fix the upper playfield issue?

Mine did the exact same thing. I went into test and didn't have any errors. Exited the test and game booted and has played fine since. I hadn't played mine in quite awhile and don't know if that had something to do with it not booting properly. If you find the problem I would like to know as well.

Will do. I will take then upper playfield off tomorrow. Fuse F6 seems to also not be working probably related.

I had the same problem along with many others when I got a family guy a few months ago.. Does it give you the check 12v error fuses 12 + 13 when the speaker popping stops?

When I spoke with Chaz from stern tech support he mentioned removing resister 86 from the cpu(it's a very small mounted component so be careful). My family guy has been trouble free since.

Yes it eventually blows the fuses and says check 12V and fuses 12 and 13. how the heck do i remove resister 86?
thanks for the response

Well mine was blowing fuse 9(controlled lamps) but that was because of a bad bridge rectifier. I still had the issue with it not booting after..

Give stern a call first they should be able to help you out.

Yes Chaz told me to remove resistor 86 from cpu. It's quite simple l, I used tweezers and a soldering iron with a very fine tip.

I spoke with tech support at stern and they told me to tighten up the "Heat Shrink" in the upper Left corner of the I/O board. I am not sure what that means. Can anyone clarify?

#12 3 years ago

I had a similar issue on POTC recently. Mine was with the 5v. I had to tighten the heat sink on the 5v rectifier. Check that all of the heat sinks are touching what they should be cooling and snugged down.

Make sure all these highlighted screws and nuts are very tight. These are your heat sinks.
