sounds like you lost a power supply . were you running a fan kit from rci? If not that is probably the problem . This is the number one issue with the piggy back large radios . got to keep them cool

The radio had a fan kit but it was removed was wondering what i need to check? All voltage on regulators check good.
Thanks for your help.

they were notorious for power supplies...

Check the voltages around Q50 and Q51, and let us know what you find.

Also try disconnecting the Red feed cable to the power amp and see if the radio now power up.
