bob_watkins1 Posted July 17, 2008 Share Posted July 17, 2008 We are seeking any information from a current Linhoff 360 owner/repair shop that has either a schematic of the board or is willing to remove the bottom plate from their own to help us identify one of the ICs. We have a blown IC that we need to replace but unfortunately the part number on the IC was destroyed when the IC blew so finding the proper replacement is virtually impossible without a reference point. It is the ONLY 16-pin IC on the board...we can send you a very good image if need be.. Any help would be appreciated! Here are the numbers we CAN read: Part number: CD * * * * UBE (where the stars are the missing numbers) Batch number: RCA 249 Thanks to everyone in advance for your help!

dave_s Posted July 17, 2008 Share Posted July 17, 2008 There's a Linhof salesman who posts on the Large Format forum. He may be able to obtain technical data for you. Link to comment Share on other sites More sharing options...
miles_s. Posted July 17, 2008 Share Posted July 17, 2008 UBE suggests CMOS inverters. Link to comment Share on other sites More sharing options...
marc_bergman1 Posted July 18, 2008 Share Posted July 18, 2008 It is probably in the RCA CD4000 series of CMOS chips. If you do find the correct IC I would would check out the capacitors before replacing the IC. Look for a short. Link to comment Share on other sites More sharing options...
