Drumulator Help

I bought a Drumulator that’s turning on and giving
me a 8888 message on the screen and then powers off after about a minute. Keeping the switch on it powers back on with the same message and turns Off. This will keep happening unless I flip the switch to the off position.

I was reading the manual under power supply and it talks about c22 the 10uf capacitor associated with Im323 as well as c25 associated with 7915-15 regulator being used for power stability.

Are these what I should be looking at first?

Is it worth it to do any type of reset first or am I not
even getting to that stage yet?

Any help appreciated.
