There could be many options that can turn out faulty for this problem 1)the power wire of the tv gone short,needs to be checked. 2)the fuse of the tv blown out ,very common problem. or 3)it can be the faulty components on the main board needs to be checked with a multimeter and that faulty component should be replaced from the board to make it perfect.

It means that the switch is active, but the power is not, im sure it is the POWER SUPPLY my dear, and it will control the power system of your TV, check the power supply on your technician, im sure it has the defects, or maybe the capacitor,, just infor it, dont make it wait beacuse it can cause SHORT CIRCUIT, that will additionally makes problem of your TV,... regards jAN_yuanjia

How long has it being doing that? Did you try unpluging from power supply for 5 mins and then plug back and power back on and see if that works? Usually bad plugs give out short circuits to your appliances and this affects tvs the most, you might need a A/C power supply regulator to avoid this happening again.

This sounds like the flyback voltage regulator is burnt out (part is around 70.00
Hope this helps!

I have a 50fx18b and it wont power up i took the back of the set off it has a red light on but nothing happens when i turn power on


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.

  • 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.

50 inch rear projection Hitachi looks like your watching in 3d


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.
