Pioneer Elite CLD-99 Laserdisc Player won't stay powered on
First post, so go easy on me. I have a Pioneer CLD-99 Laserdisc player that won't function. When I plug it into the electricity, the red power light comes on and stays on. As soon as I press most buttons on the front panel, the red light immediately goes off and won't come back on until I plug it back in. It doesn't do anything else. I suspect it may be related to a power supply or fuse issue, but I am unsure where to start looking or whether I need to order parts. Can the power supply or fuse on these be swapped without soldering similar to a PC?
Thanks in advance.
