I could have sworn I posted about this before, but I can't seem to find the post..
To whit..
I have a 60LN5400 that came in.. Backlights work fine.. No display..
Traced the problem to the TCON board.. Blown fuse..
Replaced the fuse.. Blows again.. Replaced the fuse again... This time it fries the marked part on the Main Video board...
Got a new Main Video Board.. Replaced the fuse on the TCON..
The fuse is fine and the backlights come on fine if I don't have the cellophane connectors from the TCON to the Panel..
So, I am figuring that ONE of the panel boards are bad.. Try it with the left panel board disconnected, right panel board connected... Blows fuse..
Try it with the left panel board connected and the right panel board disconnected.. Blows fuse.
So far, the component on the Main Video Board is OK. Thank the gods for small favors..
So, I am now guessing that there is a short on BOTH panel boards..
So, my question is, is there any meter diagnostics I can try to track it down and/or is there anything I can do about it even if I CAN track it down??
It's a nice TV... Would hate to trash it because of this if it can be fixed somehow..
Any assistance would be most appreciated...
NOTE: I did find this comment that has a similar issue

But it's technical enough that I don't know if it's the same issue I am facing...
