回答“Why is my TV not powered on”Surge protectors clearly do not "prevent the sudden discharge of energy into the TV when the power goes out preventing the fuses from being blown". Nothing in specifications even discuss most of that. A 120 volt protector has a let-through voltage of 330 volts. That means AC voltage must well exceed 330 volts before it will do anything. Power loss (120 volts dropping to zero) and power restoration (voltage slowly rising up to 120 volts) never approaches 330 volts. Protector does nothing. Fuses blow when a 1 or 2 amp TV demands 20 amps (a 15 amp circuit) or 25 amps (a 20 amp circuit) for a very long time - seconds. Protector does nothing to protect or blow that fuse. Worse, if that near zero joules protector (ie hundreds of joules) tries to absorb a potentially destructive surge, then a thermal fuse (a completely different fuse) may disconnect protector parts. And leave that surge still connected to attached appliances. One should learn numbers (specifications) that say what these things really do. These...
回答“Will not boot. No fan noise, screen does not light up.”In each case when emergency services were called for, "Light bulbs reported a serious human safety issue months ago. Damage because a consumer ignored obvious. " In one case, an electric company borrowed Infrared goggles from the fire department. A TV cable inside the walls was glowing red. They had also ignored dimming lights that could have been solved without any 911 services had they ignored the naive who said, "Dimming is normal". If a laser printer causes lights to dim, that is a defect often traceable to workmanship. Lights do not change intensity when wiring is done properly. A fact - not an emotion. Your symptoms imply a power controller inside the Mac sees its power button pressed and orders a PSU to power on. It sees a defective voltage. And immediately powers off that PSU. Thing such a RAM, SSD, and UPS are obviously irrelevant. That is also not insulting. That is also fact based upon what was posted.
回答“Will not boot. No fan noise, screen does not light up.”If you find anything insulting in a 100% technical discussion, then you are part of the problem. Again, if lights flicker, then a defect exists. Just because other houses also have that defect does not mean it is acceptable. When lights flicker, find and fix what is a defect. Most light flickering is traceable to bad workmanship; not a serious human safety problem. But it is still a defect that should not exist and should not be ignored. That is not condescending (an emotional response). That is you now learning from your mistake (a logical response). Lights changing intensity, in most cases, is not a human safety issue. In one case it was the obvious warning before a house exploded. In your case, flickering would have been severe, obvious, and completely unacceptable. Lesser intensity changes in other houses is also unacceptable. Others can also learn from your mistake. Did you inspect and fix that earth ground? If not, do you know what to look for? Changing light intensity was the symptom that reported a...
