I replaced the internal 3 volt F770 battery at the start of October whilst I initially had problems with one of the trace tracks detaching, I got round that problem by using a thin piece on covered wire soldered directly to one of the pads, the unit was reassembled and put back into operation, and has been working perfectly for two months until this morning when starting the vehicle I noticed the F770 did not switch on automatically, I pressed the power switch but the camera remained totally dead, I then checked the Cellink battery B it was fully charged and the output socket on the battery was showing 14+volts, then checked the voltage on the cable inputs to the camera ignition and permanent live were both showing 14+ volts with engine running, I then thought the problem must be within the camera so dismantled the camera carefully to check for any obvious faults especially the replaced 3 volt battery all soldered connections were found good, the battery was showing 2.84 volts which was the same when initially installed, I cannot see any obvious faults internally on the camera so was reassembled and put back into the vehicle, I also tried using the reset button but the camera remained dead, I'm reluctant to purchase a replacement front camera when the dual system is only two and half years old, and it appears not to have very reliable service life to date, it would be appreciated if anyone has any ideas regarding a fix for the dead camera or test I have not carried out thanks.
