I have a sceptre x405bv TV with bad LED strips. The screen displays dimly over the good LED's, and on disassembling it looks like over half of them are dead tested by multimeter diode test on test points. Plugging it in with the panel disconnected (this TV has a combined power and main board), the backlights immediately receive power when the set is plugged in. When the power button is pressed, it flashes brightly then dims, but additional LED's turn or flicker. When it's turned off again some back lights stay on.
Before I order replacement strips I wanted to ask if it is typical...
