Hi there,
I'm trying to fix an old electronic game and there's one component I don't recognise on the board, although I suspect it's some sort of step-up converter. It has 10 pins and I can see +6v going into two of them but nothing coming out of any others. I have another game that works and it has a very similar (but not identical) component which is putting out -33v on 5 pins, hence my assumption of its purpose. It has "TX-90 4 5 TDK" written on it and can be seen in-situ at the bottom of this photo:
Can anyone tell me what this is, whether it's likely to be broken if there's +6v going but nothing coming out and if so, where on earth would I find a replacement?
Cheers in advance to all you clever electronics people who know exactly what it is and where to find one!
