You need to replace convergence out chips in your Toshiba 57H81 tv by qualified tech because 3-D look picture in rear projection tv shows some thing wrong with convergence output chips. Your tv model number shows it is rear projection tv that use 3 tubes to make color picture on front screen where as dlp tv use one lamp as back light source to present picture at front screen that is generated in light engine.
If you can get the tv to display the blue blackground(usually happens when there is no antenna or cable feed to tv) check to see if the whole screen is a solid blue, if it shows discolored areas around the screen then you might have to "demag" the screen. See if you can rent a demad coil from a tv shop and with tv on turn the coil in circular movements all over the front of screen till blue is solid.good luck!
Check the signal type. It may be set incorrectly.
Change the channel. You may be on a blank channel.
Check to see if the TV is tuned to channel 3 or 4 if you are watching a videotape.
Check the TV/VCR button on the VCR is in the correct mode by pressing the TV/VCR button on your VCR.
your tv has a fault in the matrix board the blue driver volt to the screen is missing or some dried up soldering at a pin
should be seen by qualified , but sereen is ok ,
