Try to unplug the TV from the wall outlet, and leave it for 3 minutes or so. Push the on off button on. Next connect it again and turn the tv on. I see this is an old topic, But maybe helpfull.

Good day, Bgchzy;
This model is known for the tubes leaking fluid, glucose, on the PCB. Check the front of the chassis for said fluid, it may be only a drop, so look closely.
To fix, after TV has no power, try cleaning the board with cleaner and brush, let dry. I suspect this because of multi unrelated problems.

The power supply is bad and must be replaced.
Depending on the TV and what your local repair shops charge, it might be cheaper to replace the TV. This same thing happened to me. I could replace the TV for just a little more than the cost of fixing it! I'm replacing the TV.
I'm sorry that I couldn't give you better news.

SOURCE: TV was playing, then the screen turned black.
If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.

my first question is have you checked the bulb. the loud pop sound like the bulb blew and the rattling sounds like the lamos trying to fire. remove the bulb cover and unscrew the bulb
