Toshiba model 35D10 randomly turns itself off. requires unplugging/replugging at wall ooutlet to reset. problem has become more and more frequent.


replace flyback transformer (same type - equivalent will not work ) - this part's work is to supply voltage to TV TUBE - after 4 years ( 4 to 10 years - depending on usage ) this part becomes weak then in top brand TVs automatically TV senses this deffect & well in advance it shuts off TV to protect other components from getting damaged due to this flyback transformer ........... as on now in your case only flyback transformer is deffective - so replace it as early as possible ....... click below link for more details on how to replace it ......

Television will not turn on consistently


Hi,

There are far better experts from this site who would know more if you can post back specific model no or preferably the Chassis no. of your Toshiba.

Just to start the ball rolling, to my knowledge, most models of CTVs since a few years back uses an internal mini computer. Like any computer it does need to be reset and in your case, unplugging (actually for a few hours) performs a hard reset . For a few minutes is a soft reset.

At times, the standby led or power led would also flash a certain sequence to indicate if there is an internal fault detected by the protection circuitry. By unplugging, you did a reset on the protection circuitry and if your problem is intermittent or develops over a period of viewing time (chances are heat related problem), then the protect will auto activate and will not allow power on the next time (if the unit is plug).

Hope that this be of some initial help/idea. Please post back and I'm sure others would be offering detailed assistance thereafter.

Good luck and kind regards.
