Re: onkyo ht-r290 - My Next Project
Those amps are not repair-friendly.. when speaking about disassembly.
A good start will be to remove the back plate.. lot's of bolts there.
Then you will have to remove all boards which are above the bottom board ( where the power amps/ICs are ) and finally - the power amp board from the chases ( most likely you will have to remove it with the heatsink ).
And keep in mind that the backplate is used for ground connection between the boards, so there is a very good chance the unit not to want to start at all without it.
