If you unplug the tv from ac. Let it sit for 10 minutes. Plug it back in and check if its on.or
ONE: Do a hard reset. Merely unplug the power cord for 4 hours or
more. This will clear any software corruptions that might have
TWO: When you turn the set on listen very carefully for a sizzle or
crackling sound down in the lower back side of the set. This is the
high voltage coming up. If you donot hear it the high voltage generator
is faulty. If you do hear it and still a blank picture you have video
processing troubles. Either way it is not a home remedy and you will
need a service tech to diagnose the set with instrumentation.
The problem could be in the convergence amps. stk's., common failure on Toshiba TVs.
The power board which has the power transformer has a set of wires that go to the convergence circuit. If you disconnect this cable the unit will power up. Of course the convergence is all messed up because its missing its voltages, 30 18 18 give or take.
