I replaced the bulbs with identical bulbs from wallmart, but they only had 4W lights at the store. That shouldn't matter, the base was the same. Anyway they were burnt out. But the new lights won't come on at all. I opened my Furman and tried wiggling some wires to see if there was a short. Nothing. Funny thing is, there's not much to the inner guts of the unit regarding the light section. Just the switch and the variable spinner for brightness. I didn't notice any discolored electronics, so I know how how to proceed. Do you think I could get this fixed at a reasonable cost rather then buying a new unit and maybe get the MOVs replaced also why they're at it? This unit is about 12 years old. Do you think it would be worth the money to send it back to Furman for a repair?
