Hello, I came across a hunting camera HC500M with a number on the board - HC500M-3G-UC15-V2.6 20170808
The problem is that didn't turn on. Attachment 1 and 2 are the board.
First I want to ask if anyone has a schematic on this circuit board since I couldn't find it anywhere.
When turning on the camera, there is no power on the two phases that I see on the board. There is power on the battery. On the board, there is two line key for turning on the camera, on one of the lines there is power on the other one NO. I manage to trace NO power line - she goes to BIOS chip and then to PIN 1,2,3 on this chip : VUNI TI 758 A683 /Attachment 3/.
But I can't find information about it. Please if anyone can provide a schematic about this chip to post her here.
There is power on this chip on PIN 10,11,12 - but no power out. I try to measure resistors and capacitors around the chip, everything seems to be OK.
Or the signal that controls the chip is missing, or the chip is dead.
Please help me with the chip circuit or schematic of the board or if there are any other suggestions I'm ready to try them.
