Question about Toshiba 43H70 43" Rear Projection Television
When I press the power button, the TV will turn on, but it will not display anything. The power button will blink on and off, however, and the TV is on. At first, I would hit the area around the power button and the picture would work. But now, it wont work at all and the light just blinks on and off.
This unit is known for bad relay contacts. It may be that tapping in-on-or around the relay at Sr41 might restore the pic temporarily. If so, replace it - p/n#23146558.. If not, you may have some poor solder joints that will take a little bit more investigating and possibly shop time if you're not up to the task.

The lamp timer on the Hitachi projector must be reset whenever the lamp has been replaced. The "Lamp" indicator on the display will light red or the "Change the Lamp" message will display when the lamp timer needs to be reset. Hitachi recommends that the lamp timer never be reset without replacing the lamp and to always reset the timer when the lamp is replaced. The message functions of the projector will not function properly if the lamp timer is not correctly reset.
Turn the power on. Press the "Reset" button for three seconds until the "Lamp xxxx hr" message appears on the lamp timer on the bottom of the screen.
Press the "Menu" button on the remote control while the lamp timer is displayed.
Press the left arrow button. Select "0" and wait until the timer display clears.
