if your serial number starts with ha then it's probably a bad capacitor C72 . 6.8uf 100v np electrolytic. replace it with a higher voltage capacitor of the same value.

I had the same problem...replaced the C42 capacitor with one that I got from RS...fixed everything and all is well again. I only have moderate soldering skills, too, so if I can do it, so can you

More likely to be the Class D power amp module, but you should look through the service manual to make sure all the parts are installed correctly. My PB10 AMP module went out and you cannot get one anymore.
