Re: Insignia NS-LCD37 - One Second to Black - Another one
I've all ready installed a brand new A/C power board, I figured with all the main fuses and bad capacitors everyoned talks about I went ahead and ordered a new board for $46 shipped? When you say main board do you mean power board?Last edited by Daddyfixit; 06-24-2013, 03:53 PM.Leave a comment:

Re: Insignia NS-LCD37 - One Second to Black - Another one
Okay so I've tried the other pins as you asked from your diagram. There is nothing present 0V, and from the side you asked for me to check there was nothing, but the other side actually powers up on five the pins, these all lead to the main a/c board and they are stamped 24V on the bored, they all get 24.7V once I turn the tv on. The last pin when I follow to my A/C bored reads DIM but like I said its reading 0V. So there is no ON signal obviously, what do I do next?Leave a comment:

Re: Insignia NS-LCD37 - One Second to Black - Another one
Okay so I was looking at the pins you gave me to check for voltage. Looks like they run directly to the main power board, but, when I checked to see where they lead to, it wasn't what I think you were looking to see. I did however manage to see that there are four leads of the power board that go to four leads to this back light inverter board. So I am getting the 24V like it states, So this means we\re good there. Does this mean those darfon things are toast and how do I check?Last edited by Daddyfixit; 06-22-2013, 07:57 AM.Leave a comment:

Re: Insignia NS-LCD37 - One Second to Black - Another one
Well my brother here was saying that it was fine on the 750/200AC side, but I was testing it with 20 DC. which was the scale reading 2000m/200m/20/200/2000
I have a small butane one with tips that I never used before, but something makes me believe I will be using them soon? O should I use a conventional plug in type?Last edited by Daddyfixit; 06-21-2013, 11:42 PM.Leave a comment:

Re: Insignia NS-LCD37 - One Second to Black - Another one
Sorry that was 750/200. By the way the screws that will hold down the board are tiny, the only real way the boards contacts will make proper contact is if I bolt back on the cover, not sure I can take readings after?Leave a comment:

Re: Insignia NS-LCD37 - One Second to Black - Another one
Okay so I just wanna say that the cage that protects that board is off so I don't know if its still grounded correctly. But after I checked it at all the pins you asked while everything else is connected and with either power on and off they all read 0. Now should I be using the meter that reads 75/200 V? Or 1000/200/20/200m/2000m?Leave a comment:

Re: Insignia 37 inch LCD, has sound, but no video. What to do?
Hi all I have to thank you all for sharing what you do, but I'm having a problem with my Insignia NS-LCD37 also. Having said this, everyone talks about the red light on then going to green, but mine goes to blue, and I see nothing but black? I have read as much as I could about similar models but, I'm not sure where I stand in comparison to others with similar models.
The TV worked great for over five years but now no longer powers up, I only have that red light stating that I'm plugged in and when I hit the...Leave a comment:
