Sharp LC70LE640U - No Picture

[Audioplus]

LED just flashes continuously, no picture, you can power off with remote. I was thinking main board, an associate commented LED Strip, or an associated smd (sensor mounted device?), but can't find an led strip associated with that model.
Any ideas out there?

As always, thanks for suggestions!

Anyone familiar with LED Address Board ? RUNTKA842WJZZ

Thank you, I hope so? Shop Jimmy says a Main Board, Sharp says a lamp, in this service manual, it says a ROM data failure.
I can't get a straight answer from Sharp, so I am hoping if it's a ROM issue, a Main Board will do it, I picked up a T-Con for $20 just in case?

Second case scenario may be a service menu lamp reset, that would be nice?

I appreciate the assistance!

Most common from memory is open circuit LED inside panel - a pain in the behind to fix.

Nothing at all shows up on the screen, not even for a second?
Actually my LC65D64U it was the easiest to take apart.
Metal frame with the LCD panel, came off as one unit. I have never seen that one before.
Mine, it's an older LCD model and the LED flashes continuously, after showing a blue screen and channel# for two seconds, but only on one side.
I have ordered the inverter for it.
