CTS4200 Shuts Down

Recommended Posts

sheridan    0

A sports bar installation I am the tech support for has a pair of CTS amps. A 4200 and an 8200. Both on the same power in a rack. The 4200 has decided it wants to shut down several times a day. The mgrs reset the power and it comes back up for however long it wants to. The installation is about 4 years old.We will be pulling the amp and replacing it. It would be nice to be able to repair it for a backup. When I get this on my bench, what should I be looking for to determine the problem? I'm thinking that it's a PSU issue and not channel related.

Still looking for some ideas on this.

What do the front panel LEDs do?

Do they all turn off with the loss of audio?

Are the thermal or fault LEDs on?

Is the fan running when this happens?

Has this behavior been recreated on your bench or is it exclusive to being in the rack (with expected higher temperatures)?

Without the answers above, I would suggest looking into the low voltage power supply first.

This is mounted above the high voltage supply in the metal shield.

I suggest this, as it is the easiest item to evaluate.
