(New member, old carver user.) I know, this an old post but.... I have a Cinema Grand 200 5. My lamp burned out (surprise...) I thought I'd do this LED mod. I opened of the box and there was the lamp on the pcb but there was also a fairly hefty resistor (160ohm x 2w) in series with the lamp. One of the incoming leads was connected at E1 and the other was connected in common with one resistor lead (rather than at E2), the lamp was then connected to the 'normal' points. I removed the lamp and resistor. Put my fluke to the incoming leads and got .985vdc. Huh. Not anywhere close to what others have posted. Switched the fluke to AC and got 18v! At this point, I stopped to do some head scratching. Decided to button it back up and seek assistance.
Anyone seen this arrangement before?
