There is no kit and if you don't know how to test and repair this type of electronics then you need to take it to a repair shop. Polk charges around $250 for the repair.

sq nearest expert radioinstaller I'm sure he will know the answer and have the replacement part you need

Power transformers are safety parts and should only be replaced by the same type or one specified by Eltax the maker. You should contact them for the spare parts department or the place that stocks them.

Could be the power supply but the transformer may
have opened up due to a "surge". Might have to contact Polk to see whats up and/or dealer as the
amp may need sent in for repair!

1st check your PC if audio is fine with headphones or some other speakers , then check your control panel and test sounds compatibility might that you are using wrong speaker setting in the PC.
The below is the company web link to your speaker set , try this too

Hiya sounds alot like there is a power supply issue with the unit that will require repair for it to be doing off or on. Probably wont be to expensive, request a quote first to make sure viable.

Best of luck

Hi, Just call the parts line at Polk Audio. They should have the fuse. You can also ask for technical if you're not sure of the problem. Here's the number for Polk: 800-377-7655 Good luck to you.

Polk in the US are sending me a replacement pin. What great guys they are.
