Alltek Board - Elektra

[TonySchwager]

Hi all,

I have limited knowledge and have started to expand working on Elektra,
Dissembled and polished up the rust coin door and various other easy on and off metal work
Touched up the middle play field at the weekend - blues, blacks and reds, having trouble matching the face colour
I ventured into the top box and cleaned up the back glass which came up nicely
Working my way towards a re-stencilling


But have discovered a bit of frying on this board - nothing obviously wrong with LED's etc.
Should I be concerned try to get this repaired?




Thanks all

A transistor has gone up spectacularly in the past. It doesn’t look pretty but I guess as long as it was replaced correctly and everything works then leave it be

Coin door looks amazing - nice job.

Loos like youv'e had a short on one of the lamp circuits. I'd we surprised if all the lamps are working correctly? Unless the board was damaged whilst in another machine, and Elektra doesn't use that particular SCR transistor to control any lamps, but again I think that's unlikely.

Looks like Q25 and or Q29 are blown they control "Left Spinner arrow" and "2K Bonus" - so see if those 2 lamps are working or not?

Thanks for the replies
Test flashes the 2k bonus and the left spinner - all good.
Only fail is the 2 Elektra units will try a new bulb in there
