Same problem - turn it on and it automatically shuts off. It would appear that this is a problem with this product and Toshiba should compensate the purchasers. I did not see any solutions and it is hard to even find anyone to check out/repair TVs anymore because they seem to be disposable and everyone buys a new one. I have never had a TV that was so short lived. I will never buy another Toshiba. I should have stuck with Sony or Panasonic. Was there ever an answer for this problem. Mine was definitely not storm related. It worked one day fine and the next it was completely gone. This should not happen with a TV less than 3 years old especially since this TV was in a bedroom and not used all that often.
Check thje following
the power reaching your switch via a fuse and power out of the switch, when switched on.
if the power is leaving the switch okay then check the power supply components
semi conductors, for leaks and shoots, zener diodes, and capacitors for variations and change of values especially electrolitic capaciturs. if you get a high voltage of 85 and above going to the transistor near the transformer, then check your line trasistor.
