Figure the manual may be useful for you one day

I would start by checking the fuse (back of radio near AC powerline. 4A fast blow) then check the power supply voltage to radio (13.8VDC). Confirm the power supply is plugged in and sending power to the main board. Based on what you describe this should be the culprit however its always better to confirm the PS is the issue before spending money on a new one.

And, if the problem is the power supply, which as @WRAK968 suggests is a likely, it is then very likely to be caused by bad capacitors. In a well built piece of equipment, which your radio seems to be, the capacitors should be fairly easy to change. At least for someone who is comfortable with a soldering iron inside a radio  :)

Thanks .... yea i have manual , the fuse is good , repeater was up and running for close to 20 years with no problems, i think my zello device got hung up and stayed keyed but i was sure i had time out programmed into repeater , what can tell you is when i turn on no lights come on or anything but i can hear a faint high pitch sound coming from somewhere in the repeater near the power supply

If you do you not have the tools and are not comfortable inside the radio, I would strongly suggest you take it to a local radio shop to be repaired. As noted previously, it is likely a problem with the power supply, but it could be something else as well. A well-equipped shop will be able to quickly diagnose and repair the problem. However, one thing to keep in mind is, unless the radio is simply an OEM repackaging of some standard product made by someone else, it is possible that parts, particularly in the power amplifier section, might be difficult or impossible to source. It will likely not be something terminally serious, but it’s best to be prepared for what

they might find
