Hi!
I posted a followup question the BN44-00428A thread but this seems like a better idea.
On applying power, the back light comes on for less than a second then shuts off for 2-3 secs then it all repeats until I pull the plug.
Disconnect CNM801 to main, no change. Disconnect CNL801A,B. No LED flashes but relay cycles.
With reference to the schematic, Vdrv reaches just over 100V when the relay opens.

I Checked for bad solder. If I remove DM851,852, the B5V and B13V come up fine, but no light, of course.
Thanks for any tips!
I'm wondering if it's an OCP or OVP from the LED drive
