Hitachi 50fx18b 50" projection no power

the red light = shutdown led
all the green ones indicate the voltage lines that came up
there is a diagram inside that shows all the leds plus fuse locations. you need to check the fuses with an ohm meter to figure out which one is blow or which voltage doesn't come up. with that info, i can direct you.

the junk yard or craiges list

check if you enabled the sleep timer

Yes - You will need to either remove the circuit board or lift up the tray. If you are not sure how to do it yourself read the link below.

• This is a very common failure on Projection TV sets.
  
• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
  

You can see some example photos and find a solution here...

This is a problem with the convergence circuit. If you can solder, you can fix this yourself. Please note as well that there are potentially dangerous high voltages present even when the set is unplugged. That being said... Open up the back and locate the convergence ICs (large black ICs attached to a heatsink and marked STKxxx). Try resoldering the pins on these ICs first. If that fails to resolve the problem, replace the ICs. There may be other related components that need to be replaced as well, but start with the ICs.

Keep us posted.

This is a convergence problem and igf you can solder, you can probably fix this yourself. If you feel comfortable working inside the set, and are aware of the dangers of the high voltage present there. try the following: Resolder the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heatsink and should be marked STKxxx.

Keep us posted.

Press "shift" on remote to write to Rom. "Rom write" is displayed. Press shift again. Wait about 25 seconds, then press "mute" to return to convergence mode.
