Question about Televison & Video
Hey guys I was hoping someone could help me out. I have a older Sanyo 32" and recently it has started making a tiking/clicking sound when it is on. It immediately stops when I turn it off and immediately starts when I turn it back on. The clicking sound happens about a dozen times then it pauses for a few seconds and repeats this. My audio and video both work fine. I can hardly notice it when playing a game or watching tv but when I do notice it is quite annoying.
That is caused by the insulation on the EHT cable or tripler leaking.

Could also be the sound of some sparking. Before you trash the TV, or call a technician, try this. unplug the set. Open the back cover of the set, and now plug it and switch ON. Stay a little away and observe if you can see some sparking. If yes, try to localise it. Unplug the set and then wait for a few minutes and then see what is causing the sparking. Clean that area, as it could be because of some foriegn object (I have seen small rodents, lizards, etc) entering the set and getting fried. Clean it up and try the set again.

It sounds to me as if possibly ya Main IC Amp Chip & OR the Output Capacitors are failing... Sometimes it is a sign of a power supply on it's way out... Either way it's time for a repair shop quote. Either that or it may be the speakers crossovers... to check this, if you can, try another set of speaker... see if problem is still there. If it IS, then it IS most probably as I said above.. If NOT then it may be one or both of the "Crossover Network" in each speaker...

I have the same problem-still troubleshooting...so far still not find the cause. DM1 power supply output voltages are operates correctly. Signal output of microprocessor up and down (no good) that turn on Q14105 and latch optical isolator U14102 to power the unit but both of ohmed out ok. it hard to troubleshoot the main board with power on.

Its a real good chance that the HOT (horizontal output tranistor) transistor is shorted if so the flyback trasformer may be bad also. the transformer will make a tick tick sound if it is trying to start.
