How to fix my pioneer amp VSX 816 as it won't start up

I really don't recommend this product to anyone, or any newer pioneer products for that matter (except the elite line). This model has the "hybrid" design, which is a very flawed design. At first the speakers will start cutting in and out, and then some of them wont work at all, and then the receiver will flash "overload" and the receiver will go into a permanent protection, all because the receiver cant handle the resistance of the speakers(doesn't matter what speaker it is). Once in protect mode, press ENTER+ ADVANCED SURROUND and it will tell you what the problem is causing it to stay in protect mode. In order to keep this from happening, use external amps. Pioneer wants around 500 dollars to fix it if its out of warranty, it will cost at least 50 to fix it yourself, in most cases it will cost 150 to fix it yourself (most cases all 3 power modules will go out, or as pioneer calls them, power packs). If you have an older vsx model (50s-80s) then it is usually worth fixing. If your having problems with pioneer vsx 3600, 3700s, 3800, or 3900s, send me an email at [email protected] and i will help you the best i can
