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.

TOSHIBA TV NO PICTURE

Sounds like blown invertor board that powers the backlights (if it is LCD or PLASMA). If your lucky and its just the invertor board blown it could cost anywhere between £50-£150 for new board (without labour).. if you are UN-Lucky, then the backlights themselfs may have blown which is *usually* an un-economic repair.

The toshiba 46h83 46in rear projection tv comes

the red flash you are talking about im assuming is the screen going red
that usualy means a red picture tube they break down
one way to tell turn the red screen control counter clockwise and see if you can control the tube gain
and then you can lightly tap on crt neck and i do mean carfuly and see if it flashes it most likely will and you would need to change the crt and reset it up

Picture is Dark on all stations

It sounds like a bulb. I would call toshiba and ask them what the replacement part is for that. I briefly googled for it but couldn't find the matching bulb for the 46H83
