A/c blower turns slow and makes puffing sound. bryant 80% avac system.little cold air from vents


Hello, replace the capacitor as when there are storms sometimes they can cause a voltage spike and damage the capacitor. The capcitor will be a round or oval metal looking can next to the motor. When the blower motor runs slow the coil can start to freeze due to lack of airflow and this is why little air is coming out of the vents. If the capacitor does solve the problem then the motor will have to be replaced.

LCD TV NO POWER


The most common cause of Failure in this unit is power supply failure caused by failed capacitors. A visual inspection is The easiest way to identify and confirm bad capicitors on the power supply. Such a capacitor will show one or more of these symptoms: 1) Bulging of the vent on the top of the capacitor. (The 'vent' is the impression stamped in the top of the can. The impression forms the seams of the vent. It is designed so that if the capacitor becomes pressurized it will split at the seams relieving the pressure rather than making it explode.) 2) Sitting crooked on the circuit board as the bottom rubber plug is pushed out. 3) Electrolyte (a crusty brown substance) leaked onto the board from the base of the capacitor 4) Venting from the top of the capacitor, visible as rust-like brown deposits, or a visible hole in the vent Once the power supply is repaired or replaced your tv should work normally

TV won't turn on. Just get a clicking noise. How do I fix the problem?


The way to fix this failure is to replace 4 capacitors on the power supply. If your LCD has the power supply BN44-00135A in it, check the picture below to find the location and value of the capacitors.

Television will go blank after a few minutes. if i turn the tv off and turn it back on it will be fine for a few minutes. the tv is 4-5 years old


sounds like you got a bad back light or invertert, Take a flash light to the screen and see if you see a faded or distorted picture if so replace the back light and or
inverter. A local tv repair shop would be ideal if you do not know how to test these things.

Thanks hope this was very helpful to you when you cast your ratings and feedback today.
