Hello everyone, new here. I just moved across the country to Seattle and took my TV with me. I plugged it in, and the power button glowed blue like it always does when it is plugged in and it makes the sounds of turning on but the screen is completely blank. When I changed the channels I could hear the shows, when I plugged in a game system I could hear the appropriate sounds, but the visuals are totally dead.
The set is about 6 years old, but before I trashed it, I was wondering if anyone had any ideas. Maybe something is just loose inside?
Serial number: 1356000T2778000210
Model: HT-2778P
I also see something white that looks like it leaked and dried on the back of the monitor inside the set. |

| I realized the white stuff actually is just holding the wires together and isn't melted, before I got the back of the TV off I thought it was melted and leaked over the wires. |

Likely hot glue or RTV/silicone sealant.
Dust? You don't recall 60s & 70s receiving tube-type TVs.
Either of above - no concern.

I presume sound of relay click(s) & high voltage static? Is the filament (in the extreme rear) of CRT neck glowing orange? |

Yeah, those sounds. When I changed the channel I could hear the show as well, though obviously not see it.
Yes as well to the orange glow, but very very faintly. I had to turn off the lights to make sure it was actually glowing orange. You can't see it here cause of the flash of the camera and when I turn the flash off the camera can't pick it up very well. You mean the filament inside the little glass tube right?

Yep.
If you place the back of your hand (unless you have hairy palms) approximately 1/4" - 1/2" in front of the screen, you should observe the hairs move as you turn the set on.
After letting it play 30 seconds or so, turn it off and see if you observe any flash on screen. You may have to dim lights. |

| I could feel the static (during and after it was turned on) though I didn't see the TV flash when I turned it off after having it on for a bit. I turned the lights off and I still couldn't see it though I could hear it make the normal noise it does when I turn it off. |
