TV screen is black but power button lights up. No

you need to open the tv up and take out the internal fuse or fuses...go and get the right type of fuses...(the fuses will be made of glass and the same size of a plug fuse) DO NOT USE PLUG FUSES....if that fails then you need to take it to the tv repair man

It powers up but no picture? In my experience with Hitachi TV's this has been an issue with the convergence IC's failing. You will need to have a technician replace those if needed.

Power is on but no picture or sound

Check the solder connections on capacitors C809 and C810 they are located on the left side of the chassis looking in from behind also check fuse FL860 as the solder joints could open that fuse. usually when the power led lights but the set wont power

Toshiba 50H81 TAC0151 Blowing Fuses, I Need schematic

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!

46" projection not coming on

You have an power supply problem & or a high voltage flyback transformer gone bad. The regulator is usually an STK followed by some numbers, located on a separate small board above the main chassis in the rear of the tv. The flyback is down on the main chassis & has a red high voltage lead wire coming out of it that goes to the high voltage/focus block.
