BABY MONITOR OVER VOLTAGE APPLIED
Not sure if anyone can help me here.
applied incorrect voltage to this circuit. i think around 9/10 volts were applied instead of the 4-5 indicated. of course it stopped working. not sure if it can be fixed. i've been testing at certain points to see what has blown. 1st transistor looks ok. but the 1st processor/opamp? i'm not sure. it has 5 connections. only 2 are showing voltage (inputs?). the other 3 0volts. any help would be apppreciated. thxs. |
