Television Locked screen

This fault sounds like failure of the LINE OUTPUT TRANSFORMER.
It can be fixed, but may cost you around $120, possibly more if you have to call out an engineer.
Best NOT to use the TV as it is, because it could possibly damage the system.
If you do use it, this line will become permanent and if you get the TV fixed later, there will always be a burnt section of the screen where the line was - so I suggest you either pay to get it fixed right away, or consider buying a replacement.

Hope this helps!

This is a perfect example of a Television going into the protection mode. By that flashing light on the front panel it's telling you that there is an internal defect. There is no way to bypass that and it would raise safety concerns even if you could. The only solution there is to have the set diagnosed by a professional. If it's more than 10 years old replace the set. If it's less than five years old it might pay you to get a diagnosis. Between 5 and 10 years it's a gamble, you might be better off spending the money on a new TV. Toshiba is a reputable brand and there are many other choices out there.

The screen is the most expensive part of the whole TV, save money for new set.

Use the code 7777 to erase the current code.This will set the code back to the factory default code which is 0000.

There are some capacitors on the power/HV deflection board that usually blow. You can actually see that they have vented on the top. Cp150 is the most common to go.

they are expensive try to buy a used one make sure it is not scratched

It needs to be brought into the repair shop for service. There is nothing that you can do to make it come on. It's just an old set.
