Re: converter problem

Have you been connected to the same power source for all three? Might there be some problem that is coning from that power? With three of them, I tend to think that the power is the problem, not the converters.Â
 I have worked with electronic equipment form more than 40 years. A modern surge protector uses a device that shorts any voltage above it's set point to the return, but it does not connect the leads together. If it did that, the device could never work since it takes a voltage difference across the appliance to move the current through it that makes it work. Most devices that are sold by the RV supply stores are actually power line monitors. (Surge Guard, Progressive, etc.) The not only provide suppression for a power surge but they also protect the RV from either over or under voltages, from improper wiring of the outlet or failure of some part of the power supply circuit. The cable to your TV that comes from the antenna has no power to it so unless the antenna is struck by lightning or something, there will be no surge from it. If the TV is connected to cable TV, there is an arc arrester in the connection box, as required by electrical codes. It could pass a lightning strike, if that were to happen I suppose. Since the voltage on a cable signal is in the micro-volt range that's about the only way to get a surge from it. A surge suppressor does the same thing for any item, whether all parts are plugged to the same one, or not.
