Maybe you're expecting too much. Evaporative cooling doesn't work really well. It's function depends on evaporating a lot of water into the air. If the air in your room doesn't have a really low humidity (really dry air), then evaporation can slow way down or even stop regardless of how fast the fan is blowing.
what is the weather like is it humid ?
Humid weather will render any evaporative cooler ineffective !
Have you got the windows and doors open to the building ?
Evaporative cooling relies on putting water in the air and pumping the air out of the building. If it is humid the air already contains water and no extra water is added to the air and no cooling occurs.
Please check other question on this subject, but long story short is that the unit needs to be completly defrosted, your freezer is what cools your fridge and if there is ice build up on the evaporator air cannot flow through to the fridge.
This TV might have been affected by the power outage even if it was not ON at that moment. There is a standby voltage still present even when OFF and connected to the AC line.
There might be different failures on this TV:
1. The power supply might be defective after the power outage.
2. The main board could also be defective since the power supplies for today's TVs are not well regulated and once the voltage getting to the power supply increases, the standby voltage voltage will also increase damaging voltage sensitive components like the microprocessor or memory circuitry.
If your compressor is running and there is no indication of frosting on the evaporator (Cooling coil inside) you may have a problem with the refrigerant charge. Since these are sealed systems you may have to get a technician to tap into the system to check the pressure. If this is an older unit check the name place inside the left door and let the tech know the type of refrigerant the system has in it. such as R-12 prior to 1992 and R134A after 1992.
