Question LG 55LW5600 3d TV having a startup issue.

This issue started about 3 months ago. The odd thing is, if we turn it off, turn it on a few to couple dozen times, sometimes, it will load up and run fine. Boots up, does all expected things until we turn it off. What we started doing was just using the energy save mode to turn the screen off but keep the TV on. That lasted for a few weeks but I want to get it completely fixed.

I took it apart and found no apparent blown caps. I reseated all ribbon and cable connections and looked for burnt resistors. I just can't figure out what's going on. Any help or suggestions would be awesome. I don't mind replacing an entire board. I just want to make sure I'm getting the RIGHT one.

I have the tools and knowhow to replace caps and such. Just no proper way to test them all or figure out which ones to replace (if that's the problem).

We have had this TV for nearly ten years and it's the best 3d option out there in this price range. Any help is GREATLY appreciated.

Thank you guys.
