Check the model number. If it is 56038518, they have a 100 percent failure rate of the microprocessor built by North American Philips (NAP), the same people who make the really miserable Magnavox and Sylvania tvs. There is a list of many problems they can develop, and they can be intermittent. It is very common for the problems to show up after disconnecting the battery or radio connector. There are "reset" circuits that place the microprocessor circuits to their starting points when power is reapplied.
A lot of people blame the mechanic when this happens during other service work. Welcome to their world.
There is a different model made by Mitsubishi that looks the same, mounts and plugs in the same, and runs the same cd changer. It has the same three lighted tone controls but has one extra button in the lower right corner for "Scan". As near as I can tell, these were only used in the Neons.
If this doesn't sound like your radio, or if it is not the model number I mentioned, be sure BOTH fuses are good. One turns it on with the ignition switch, and one is for station preset / clock memory.
