Sir, the supply power of yours is the newest.
Did you test the voltage after the line go up?
Please turn on the device and wait for a few minitues, when the line go up, please test the voltages again. Author: Yleon Time: 2017-4-27 20:49
The voltage does not practically change with the shift of the line up. Now the line is shifted immediately upwards and goes higher in 30 seconds. Can any capacitors have dried up? Author: amy Time: 2017-5-2 16:59
Please measure the voltages in the pictures.
