This is the camera used to film most of the videos, & recently has suffered from a large piece of debris collecting right in the middle of the pickup area. Micro surgery need. Brushed off the CCD, & re-assembled.
Not a vacuum tube within sight on this stuff! So I assume that battery is for short term retention of the date/time, etc if the main battery is removed or fully discharges? Can you easily pop it out or is it retained on all sides? If you can get it out sure there's a number that would give you a replacement. Is there a silkscreened reference # nearby? Even if not replaced, you might want to get it out as the corrosion from it could damage PCB traces/components. Good Luck and Merry Christmas!!
Thank you. It is soldered in place, & it's so tiny. Yes probably best to take it out completely to avoid corrosive damage. Cleaned the leakage for the moment. Merry Christmas to you as well! Thank you for watching.
