EMERSON-MODEL#VT911OA-W VERSION-C

If the set will not turn on with the power button on the front of the set, you must then try turning it on with the remote. You must be sure that the remote is working correctly. If the set turns on with the remote, then your power button itself is bad or has cracked loose. This is easily fixed without having to replace the board. If the set does not turn on with a working remote, then something inside the set has failed and it should be serviced by a qualified tech.
