I am working on a friend's Time Fantasy. He said while playing the displays went out. So when I pulled the backglass I found this. 20220925_112452 (resized).jpg20220925_112452 (resized).jpg

It is a sk3202 transistor with the cover broken. 20220925_115358 (resized).jpg20220925_115358 (resized).jpg

Would this be the cause of the display not functioning, and if so is there a better transistor to replace it with? Thanks for any info I can get.

Quoted from Rikoshay:

yes that looks like the culprit but those transistors aren't made any more.
the substitute is MJE15030 but can't be put in as per the original.
please see here for example: https://www.actionpinball.com/parts.php?item=MJE15030
IMO you should upgrade the power supply, maybe as per: https://pinside.com/pinball/forum/topic/vids-guide-to-bulletproofing-williams-system-6

Thank you for the information. Not knowing the specs of the transistors in question, i am assuming that these I found on the internet are not the same, drop in replacements?
