hi, i put the resistor R23 which was smd, but i put through hole resistor and it started working and it stopped becoz the solder came out,its too difficult to solder with my big solder point .. when i tried to solder again the whole strip came off teared apart.. ,please help me in identifying connections in this pcb...
i get 16v at one end of the resistor but nothing on other end of it which is connected to junction.. i dont understand what result to get .. what points to join now.. there are some copper heads visible when i scrached to see the line so i can jump ..
