Re: 42" LCD Insignia - Sound but no picture repair.
No problem. I hate seeing tech issues online and then the OP goes off to try something or just replies back "fixed it thanks!" without telling how they got to that point. I just ordered the part and installed it and boom, power button on and everything is perfect.

Re: 42" LCD Insignia - Sound but no picture repair.
Hey Guys,
I received the replacement T-CON board in the mail on the 14th and installed it. I plugged it all back in and checked the voltages and they're all looking good. The replacement was the thing that fixed it. the picture on HDMI popped right on after I powered it on! 30$ spent on a free TV to make it back in working order. Thanks everyone for your help and assistance!Leave a comment:

Re: 42" LCD Insignia - Sound but no picture repair.
So would you postulate that it's the TCON board itself is bad/damaged, or lack of power from the mainboard?
Regardless I bought the replacement for 20$. Should be here within 3-4 days and I'll report back after installing it and we'll go from there.Leave a comment:

Re: 42" LCD Insignia - Sound but no picture repair.
Here's a photo of the voltages I got on the two pink circled areas. For the Shiggles. The one in the upper center doesn't have the 12V~ that the one on the left did. Would that mean that something is failed in that particular "chip"?
Is this TCON board something that, if replaced, would fix this issue hypothetically? Or I assume we're still in the troubleshooting/diagnosis stage? Sorry, haha, had a couple beers for a liquid lunch....Leave a comment:

Re: 42" LCD Insignia - Sound but no picture repair.
Budm, since there isn't any voltage going to those areas what does that mean? Does it show the TCON board is needing replacement, or perhaps lending to an issue with the mainboard and the power not going to the tcon? I'm sorry I"m kind of slow with all of this stuff guys. Kind of learning as I go. What should I be looking for from here on?
Bamm, I've checked the voltage in the areas you highlighted on the bottom and I was able to see 12v on a few, but I don't know what to do with that information or what...Leave a comment:

Bamm, could you be a bit more specific please? could you possibly use that voltagechecks1.jpg and highlight or circle the area/pins that I should check?Leave a comment:

I tested the 3A fuse and both sides came back as 12.1-3Volts....Last edited by Mershwer; 06-10-2014, 10:14 PM.Leave a comment:

Philips LJ94-23325B (PNF10180) T-Con Board for 46PFL5706/F7 is what I found on the website you supplied. It's a perfect match for what's in the TV. Now that I've located it, where would I utilize the voltmeter....Leave a comment:

Re: 42" LCD Insignia - Sound but no picture repair.
Roger that. I'll check the TCON board when I get off work. I have a voltage meter, but forgive me as I don't know how to check the voltage per se. I know to put black to ground and red on the solder/connection, but I'm not entirely sure which setting on my Meter to use.
What would a SMD fuse look like? I'm pretty certain i know where the TCON board is. I'll just need to take a metal panel off to get to it I think. What should the voltage be reading as for a normal working connection?
Thanks for the...Leave a comment:

42" LCD Insignia - Sound but no picture repair.
Hello Badcaps fellows.
This is my first post here on this forum. I chose it as it seems to be the best put together and I see a lot of solid advice and information here. I'm looking for assistance in repairing my TV. it's an Insignia LCD NS-46L780A12, 120V~ 60Hz 250W.
The issue is that the TV comes on, (LED goes from red to blinking blue three times and then a solid blue) and then I can see the backlight come on, and have heard sound coming through speakers when I had the cable still hooked in. However, there is no image on screen, even if I use a flashlight in the... -
