Just moved into a new house and there is this one light switch that was taped over into the "on" position. My son decided he needed to flip it and when he did all the lights on a quarter of the floor turned off and won't turn back on again. I've flipped every breaker in the entire panel and they still won't come back on. I tired one of the bulbs in a lamp and it works so they didn't blow out or anything. The previous owner must have known about this or they'd never have taped over the light switch. Any thoughts on the cause or a fix? Shouldn't someone disclose something like this before selling a house? All the outlets in the area work, just none of the lights in the celling. I'm going to check again when it's light out but I'm pretty sure there is only one electrical panel. Oh and I've cycled all the GFCI outlets that are in the dark area.
