Check the fan connections at the back. The connections (just two flimsy metal prongs) came apart (I believe), so I have had to re-enforce them with electrical tape so the connections stay together until I investigate a further replacement fan. For now the connections are extremely sensitive to motion/viberation/impact/etc... but it does work now.

Turn it off...remove all the speakers and turn it on....If it goes into the protect mode. you have a bad power amp. That's the big black flat things attached to the cooling fins.. one or both is shutting the system down. If it doesn't trip out, plug a head set into the phono jack and see if you can hear the music there. Can you turn it up without tripping.... if it's still ok...hang one speaker on the system, if it trips thats the bad leg...check the speaker/wire

Hi mate, had the same problem with my amp.. Take the top off and there is a fan at the back, there are 2 piece's of copper flat wire that touch together and these do not touch anymore so when its turned up or the bass gets stronger it cuts off as the fan should kick in at this point. If you can get these to touch again (bend them) then the problem will be gone!! I have had to do this a few times now though so this is not a long term fix.. I may try soldering!

Check the power relay RL703, I have seen these with burned contacts cause this problem a few times on this unit. Replace relay or bypass the two normally closed contacts.
