Re: Toshibia 40rv525u Green Blinking light and questions about Caps!!
Okay, 5V is good. This might be your standby voltage. Normally, the legend is marked as 5VSB or something like that.
Pin 13 is probably your power on signal from the main board. Normally it is > 3V, and if it is pulsing, then something isn't quite right.
I circled 3 voltage regulators on the main board.
1) List each part number.
2) Measure each pin (except the tab) with respect to ground.
3) Report all readings like the following.
U101 - AS1117-33
pin 1 - 0.0 V
pin 2 - 3.3 V
pin 3 - 5.0 V
If the voltage regulators check out, we need to check other things on the power board.
