Changhong plasma TV PT32600 light does not turn on the fault, because the machine uses LG's 32-inch PDP screen, according to the previous maintenance experience, first measured the power supply of each screen power board such as VS.VA, and found that the VA voltage is not a boot Yes, but slowly rise, so the machine's power board is repaired separately, disconnect all connections, turn on the AC22V voltage, at this time the power board works alone, VS, VA voltage is not normal, wipe When C210 and C211 were found, it was found that the capacitor had a low burst, and the same type of capacitor was used. Later, this machine encountered several other units, all of which were faulty. The fault phenomenon is that sometimes there is no sound when the power is turned on. Some screens flash brightly on the black screen, and some lights do not turn on. If some people encounter this type of fault, first See if this capacitor is intact.
Temperature And Humidity Sensor
The temperature and humidity sensors mostly use the temperature and humidity integrated probe as the temperature measuring element to collect the temperature and humidity signals, which are converted into current signals or voltage signals that have a linear relationship with temperature and humidity after being processed by circuits such as voltage stabilizing filter, operation amplification, nonlinear correction, V / I conversion, constant current and reverse protection, It can also output 485 or 232 interfaces directly through the main control chip.
