Clark's right. What you're looking for is a PAV board (power/analog/video) that mounts underneath the CRT on top of the perforated aluminum divider panel. Most PAVs I've seen for sale on eBay come with the big silver video board thingie attached via cables. The PAV is not the upconverter board, which is directly attached to the logic board (on the bottom side of the aluminum divider panel). Note that there are two PAV boards for the G3 slotload iMacs. There were providers of CRTs, LG and CPT. The LG name is embossed into the black plastic molding on the CRT neck. The CPT molding on the CRT neck has no identifying name at all. Here's what the service manual says about identifying the boards: There are two power/ analog/video boards in service stock. The part numbers are 661-2465 and 661-2466. These boards must be exchanged like-for like. The 661-2465 board can be identified by the presence of a switch at location SW901, located near the flyback transformer. Here are the switch instructions: If the computer has the analog board with the switch, the switch must be set for the type of the CRT (LG or CPT) tube in the computer. If the power/analog/video board or the CRT are replaced, make sure to set the switch to the appropriate position. So, if you've got an LG CRT, either PAV assembly will work. Just slide the switch on the 661-2465 to the end marked LG. If you've got a CPT CRT, you must have the 661-2465 board; the 661-246 board will not work. You can easily determine which CRT and PAV board you've got by shining a bright light through the case in the area underneath the handle. Good luck ... and check back with us for proper CRT discharge procedures since I'm sure you don't want to get zapped.
