The TV does the same thing with Lamp installed. That arcing/clicking noise.
You can easily hear this noise when TV is fully assembled from the front, or when disassembled and looked at from the rear.
All three red LEDs flash at same time continuously when it finally gives up after a few arcing cycles.
Lamp has been replaced about 2 years ago (not by me)
Lamp was from large TV-focused sales/service shop in SoCal
No appeared attempt of lamp trying to fire
The other thing...The lamp bulb shows a broken part of the filament. It wraps around the glass stem of the bulb (inside outer glass), then goes down the stem towards base, and breaks. You can also see a portion of the wire running down through the stem.
I can check with ohmmeter for continuity?
