Question about Toshiba Televison & Video
When the power button is pressed the power light blinks once as if the tv is on,but its not.there is no picture or audio
The real deal here is the protection circuit has activated. This is
caused whenever an excessive amount of current is being drawn from the
main power supply. Upon detection of same, it immediately takes over
the power management of the set and shuts it down. The clicking sound
you hear is the ON relay turning on the set, but immediately the power
mangement system shuts it OFF. You should hear two clicks, but they
may be so close together that it sounds like one click.
This set is getting rather ancient and I would not recommend you spend much money on it for this reason: It is highly likely that once the set if repaired that another failure would occur. This is because of the law of averages; the first failure is often followed by another failure from anywhere within the set.
