Mega CD Repair

Recommended Posts

Hi

 

I am currently repairing a Sega Mega CD, but am having trouble locating a chip - BA6393FP. I can find plenty of 8-pin chips with the same designation, but can't find a supplier of the correct CD driver chip. Does anyone know a source for these?

 

Thank you

Thanks Yurkie - I have the spec. Just struggling to find the chip. It seems it shares its part number with an 8-pin chip! I've found a possible supplier in China - just waiting now to see what arrives...

Unfortunately they sent a through hole part. Is anyone aware of an equivalent? I've seen BA6392FP for sale - it seems to have a similar spec., but a lower rating, so may not be any good.

 

Thanks

I don't generally approve of sacrificing systems to get parts for other systems, but if you find another one that's broken for whatever reason and is for sale for parts, you could try taking what you need from it.

Even non-working drives seem to sell for nearly as much as working ones, and I don't want to buy in another non-worker only to find the same part is faulty!

You should be able to drop in a BA6396, which is still available from shops on eBay. If pins 5 + 6 on the PCB aren't isolated from the rest, as grounding N/C pins is common, you'll have to lift or clip those leads on the BA6396, as they added external connections to the internal 5v regulator on this IC, and grounding those pins will short out the internal regulator.
