Well without the schematic, knowing Toshiba they have alot of convergence problems, so see if the fuse blown in the convergence area, if you you may have to replace convergence amps. These are the big STK's. Most of the time there was a color problem with set before going out. If no problem with this on your set then look in the HV area Hor. and Ver. area. Hope this helps!

Toshiba 50H81 Has Power but No picture or Audio

ok i'm goin to need more info about your problem. you stated fuses and didn't say the location numbers of the fuses. Also, have you rechecked your fuses to see if they are all still good? 3 fuses sounds like more then one problem. once you tell us your loc#'s of your fuses, we can look into your problems.

Service manual (schematics)

I just bought a service manual on Ebay. I'm not at home so I don't remember the vendors name, however it was $8.50 and the documentation seems complete. I also just found this site: which contains a block diagram but not the full set of schematics. If you really need the schematics let me know and try and get them to you.
