Hello friends!

I would like to ask if someone had this problem with POLY800.

It turns on. Eferything works good. After 2 minutes of play it starts to play random keys very fast for some time and stops. when i start to play again it again generates random keys. After several tries all sounds resets to noise. I can upload factory sounds from tape and again everything goes the same as before.

thanks

D

It could be a dirty signal path, due to dried electrolytic capacitors, or dirty DC voltage. As first you can try with another power supply (it should be extern, if I remember correctly). If it doesn't help, it could be some bad capacitor inside. In aged electronic boards, the first things to check/replace are the electrolytic capacitors.

Check the memory storage battery.
Good luck for opening that plastic horror.

Yes right, it can be more likely the battery in this case, if all the sounds ghe reset to noise.
