Is my H-K home theatre amp worth repairing?

Due to Covid and the deaths in the family this cheap AVR 171S stayed in the box for a couple of years.
I started to set it up just before Christmas and I can't get it to work.
It's a warranty problem I am sure but due to my slackness it was purchased 3 years ago and the warranty is only for 2 years.
I hate to toss $900- in the bin but I also don't want to throw good money after bad and I'd appreciate an opinion.
H/T is for fun and movies with the grandkids, analogue stereo is what I normally listen to
