Kenwood VR-6070 no sound?

you need to replace the amp i have worked on receivers for 8 years now and it is verry common for them to blow a amp but i will worn you the amp is a pricey peice

I sent my unit to the repair shop back in January, in two weeks they diagnosed the problem as cold solder joints and a few bad capacitors. about a month later it started doing the same thing again - so in March of 08 I sent it back and they still have it to this day. I've contacted them and they say their repair guy has invented some new curse words for it.. but has not yet repaired the problem.

He has said that he's replaced the face unit and it did not fix the problem.

After it was repaired the first time, the unit would produce sound immediately after being turned on... a week later, i had to set a pillow over the vent holes to make the unit heat up a bit before it would produce sound.
