ok i have a big screen rca tv. its one that has the three colored bulbs. it now has no sound due to a power outage last night when it was raining. the rca inputs and rca outputs all work. the speakers for the tv does not work and there is also speaker output terminals on the back and they do not work as well. i would greatly apreciate any suggestions on where to start on the repair. i took the back of and the input/output board doesnt have any blown capacitors and does not look burnt any where.
