Hello: my problem is that I have audio but not video is not seen at all. Abri the part of behind of the screen and I see that two pipe estan subdued(switched off) does not have light.
My e-mail is email@example.com If the agradesco can help me Thank you

Frist Kyle count the number of blinks on the set when it shuts down, this is an error code related to the problem area., The most common failure in this model is the deflection power supply board. This board provides high voltage to the picture tubes and related large signal circuits. You may want to check the horizontal output transistor for shorted condition, if it is found to be shorted replace it an the flyback transformer as these two work to gether to produce the horizontal frequency to produce the high voltage.
CK your hori output Transistor and small blue capacitor round it feed the hori output 2k high voltage cap if they are OK then Replace both of your STK ICs they will have part number on them. For Parts Call Mats 1-800-628-1118
The problem you described is caused by poor voltage regulation in the High Voltage power supply. This can be caused by a defective fylback transformer, a defective focus block, a defective HV trippler, of the horizontal output transistor/damper diode assembly. I would first check the high voltage from the flyback to see if it was fluctuating, you can do this with a high voltage probe. The I would check the horzontal output transistor out of circuit with a transistor checker to see if it passes.
If you do not have equipment what you can do is remove the deflection/HV board and order a replacement from panasonic.
Look up Panasonic's web site and contact their technical support number and call them to find out the part number and have them order the part for you. If this fails try PTS at http://www.ptscorp.com
from what you descirbe this is an idication of a faulty flyback. the flyback is a special high voltage transformer that generates high voltage for the picture tubes. when you replace this you ussally replace horizontal output transistor. THis repair usally run 125 to 300 at our shop.
You have a shutdown circuit. The shutdown circuit is working as it should by not allowing the TV to come on if it has a HV (high voltage) problem. This could be caused by a shorted HV Transistor in the Horizontal section or a defective IHVT (Integrated High Voltage Transformer). In any case you will have to get a qualified TV repair person to troubleshoot and repair this problem.
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. http://servicemanuals.vstore.ca/
dont know about warranties but horizontal lines means your horizontal frequency which runs about everything has drifted off sync and if too high or low it will activate shut down circuits in high voltage and power suppy, even causing HOT transistor to short.
good luck and call a tech.
