Re: Voltage level on LCD power supply board.

Success! I replaced N6 and put the board back in and if fired right up! Now lets see how long it lasts.

Thanks for your help budm.

Thanks BUDM. I'll give it a try and report back.

Re: Voltage level on LCD power supply board.

Measured the voltages on the regulators.

N1
pin 1 - 2.09
pin 2 - 3.33
pin 3 - 5.26

N7
pin 1 - 1.37
pin 2 - 2.63 - stub
pin 3 - 5.25

N10
pin 1 - 9.38
pin 2 - 0 - stub
pin 3 - 5.03

N5
pin 1 - 2.09
pin 2 - 3.34
pin 3 - 4.96

N3
pin 1 - 2.11
pin 2 - 3.37
pin 3 - 5.25

N6
pin 1 - 0.71
pin 2 - 1.42 - should be 2.6
pin 3 - 5.25...

Re: Voltage level on LCD power supply board.

Hello,

I've been reading this thread to repair a Dynex DX-L40-10A tv. Had the same power supply problems described, ordered new caps from Mouser and replaced all the electrolytic caps and the film cap on the board. Put it back together and it powered right up. Unplugged it to move it to a cable outlet and back to the red LED and no picture. After opening up and testing the voltages on the main board I'm getting the following:

Main - DC Volts
+5V - 5.27
+5V - 5.27
GND - 0
GND -...
