SOURCE: Power on but no picture or sound
Your problem is from the power regulator IC . Its an str type and has to be an original from tosiba or its parts distributors. Now you may have caused more problems as alot of peeps do trying the set over and over again thinking Oh the set will rest its self.. Nope sorry sir if a set goes bad and you try it once , and it dosent come back on . Its time to seek a repair person to repair and troubleshoot the set for you UNless your a technician? If your not Dont try to repair a tv as these have non serviceable parts for the consumer to replace! And can bite ya in the butt, if your not carefull. We techs cannot teach ya overnight how to fix something. Only assit and to point ya in the right direction. Good Luck

To force the reset, try this:

If the relay clicks you most likely have a leaky diode or bad transistor in the stand by or start up circuit. There is a manual available for that model called. Toshiba Power Supply and Shutdown circuit Troubleshooter. Its available at the following link. It gives step by step instructions so you can figure out exactly whats wrong with your set. The site emails it too you after you place your order and they also provide free unlimited tech support so you will have a resource for help if you need it. I am one of their on line support techs. I highly reccomend that Manual to any one with a toshiba that will not power up. Here is the link.
