Question about Standard (CRT) Televisions
We have a Toshiba TV (let me know if you need the model # - it's only about 6 yr old). Every once in a while it will not turn on unless you unplug the set, wait about 5 seconds, and then plug it back in. We've had a repairman out to look at it, but he couldn't figure out why this occurs. This has been going on now for about 3 yr. We have resorted to plugging the TV into a power strip which we turn on & off in place of unplugging the TV. Have you heard of something like this before & if so, is it fixable?
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.
