If you input an AV signal have you at least sound?

Sorry it took a while to respond. The past few days have been hectic.

Yes I have sound. I hooked my laptop up to it via hdmi and played a video clip and the sound played through the TV.

Does that mean the problem is likely the panel is completely dead? or possibly the t-con? When I first put the tv back together the ribbon cables going to the t-con were off a little..maybe this shorted something out?
although the fuse is not blown so that is probably unlikely?

thanks

I noticed the tcon cables being offset as well. In fact I thought I killed my panel when I first fired it up.

How much is a replacement tcon ?

It's possible!
Note: my keyboard is not working, used onscreen one..
I see in the tcon photo there are on the right 3 testpoints, Avdd, Vgl, Vgh, test them in volt and report here, the others 2 tensions must be around 1v and 3,3v, you have to search them testing all the coils both ends.

Those t-con test points measured AVDD 1v, VGH .9v, and VGL .1v

A replacement t-con is fairly cheap for this TV at around $5 shipped without ribbon cables and $9 with.
Does it seem like the t-con is the problem?

thanks

I received my t-con today. I installed it and the TV now works.
I was hoping that small crack would only affect the corner where it was, but nope it causes vertical lines top to bottom on the left side of the screen.
I temporarily put some painters tape over the lines and it helped a little.

So while far from ideal it works. I think I'll hang it out in the garage and watch youtube vids while I wrench.

thanks everyone

In the past to keep air from getting into the panel in spreading the crack I have used super glue along the perimeters of for the crack where it starts and ends including the crack along the screen if it's surfaced.
