AKAI PT5492S - Makes a ticking noise,black


This usually is indicative of the EXTREMELY HIGH VOLTAGE anode connection somewhere between the flyback transformer and one or more of the crt picture tubes or the splitter. Being that this circuit has a running voltage potential of over 30,000 volts if you are not familiar with these YOU CAN BE KILLED messing with it!!! What happens is that there is a breakdown of insulation over time usually from dirt or other environmental contamination. Usually a good cleaning and replacing the HV anode wire that has failed. (hint) it will be the one that the "ticking noise" is coming from. The ticking noise is actually the high voltage arcing to the chassis/ground.

Be careful!!!!

Input cable piece broke off akai pt5499hd


The coaxial input can be soldered back in. You will need a new one however. Sometimes the internals in the tuner (where coaxial goes) may be damaged when coaxial connection breaks out. If that is the case a tech may charge more money. But just to replace the connection should be relatively inexpensive.
