I had the same problem that numerous people on this forum have complained about with my JVC-36-980. Would not power up. I followed the advice that was suggested in the forum to swap out the 1000uF 35V capacitor. Set now works great. It is a very simple fix and is worth trying before calling a service repair man. I am far from an electronics wiz and I had no problem replacing this capacitor on the circuit board The capacitor is located at C926. I am not saying that this will fix all power up problems but there appears to be a problem that is occuring with the xx980 series after about a 5 year period with this capacitor. JVC should have a recall on this and fix the part. I wonder how much money has been charged by repairmen over the years to make this simple fix ? I think I have bought my last JVC. Thanks to the internet I have saved a couple hundred dollars.
