Re: Sharp 2DR-S100S Ticking sound, will not turn on
Does it tick all the time are just a few minutes and can you turn it off and back real qiuck and see or hear high voltage come on are see a flash is sounds like you have what is know as startup are shutdown circuit trouble

Even with the tv turned off, the power supply is still active.It's supplying voltages to the microcontroler, that's why each time you press the power button on remote the tv respond by turning on. First check the power cord to be well connected in the power-bar and if it's ok...well the power supply is defective and due to the high risk of electric shock i suggest you to call a technicien.
P.S. I respond here because I don't know why our chat session got disconected.
if your could hear a slight ticking (tick-tick tick) or whining then some electronic component might have been damaged (shorted). if you have no experience repairing electronic equipments then i suggest you to send your TV to a service station!
ticking sound (like a Watch) coming from around the Flyback Transformer but I don't see a spark is called EHT voltage .
if eht voltage is ok
1 check filament is glowing or not if it is ok check voltages on crt.
2 if it is ok check luminance section in chroma section.
if filament is not glowing check for low eht due to hor section
check power supply output also.
I think you have a short somewhere inyour set most likely the horizontal output transistor which may have shorted by the high voltage transformer going bad.
The faint ticking sound that you hear is the power supply trying to start but the shorted load won't let it.
