lock for picture on the lcd but thi picture have to be very dark open it check for blown capacitators or blown fuses :D

It's a corrupted firmware, dude. As you may have "automatic firmware update" activated, your tv auto-updated itself at night and, when you tried to turn on next day, you realised the screen is blank and the menu is inaccessible. The only thing you could do now is go to a Toshiba technician and ask for a firmware update. It will solve your problem, as far as it solved mine too. If you don't have guarantee, they'll probably charge you for the update... but don't worry: it mustn't be very expensive.

Good luck.

Go to menu on your remote control and select picture setting and try selecting "default" setting to seeif you like the color, if not adjust contrast to about two thirds of the way and brightness to your liking and color to about the middle.

TV was on, screen went black... Stanley cup playoffs double OT continued sound only. TV now just clicks on and off. 

i had the same problem! i just changed my scart leads to some quality gold ones, this made the picture a lot crisper . hope this helps :0)

IThe back;light is not working corectley if it is under warranty it should be returned, if it is a 32/42 C3030 it is an old model in the UK other countries may use different model numbers
