Hi,

PSU has tickling sound problem. I read that changing the regulator IC
will solve the problem. So I change the KA3842B Controller IC with
UC3842B IC (On Semiconductor). Tickling sound disappears but PSU could
not power on the Point of Sales terminal; just managed to flicker on
the terminal display only.

Should I use only the original KA3842B Controller IC?

Thanks for your advise.

PSU (Portland State University) reports they have many tickling sounds.
All the way from grunts, guffaws, and screeches, to high-pitched shrieks and
gasps.
