Question about JVC Audio & Video Receivers
If what you mean by "doesnt turn on" that there is no display, no light indicators, generally dead, then chances are that a fuse or some components of the power supply section has failed. If on the other hand, you are referring to a constant standby, there is indicator of power coming in but not switching to normal mode, then the possibility is that the built-in protection circuitry is disabling normal poweron to prevent further damage. This could be caused by abnormal current flow/damage of the amplifier section.
Repairs would involve opening the unit for a look & see. A service manual or at the very least a schematic diagram would help isolating defective sections/components. This of course would also require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron. Parts could be purchased from any electronic parts store near you. Probably best would be to desolder the determined defective parts and bring them along when purchasing the parts. This in effect would be "as per sample". Alternately, you can source parts online.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
