Question about Hitachi 53FDX01B 53" Rear Projection Television

1 Answer

No picture and no sound

Like the title says I get no picture and no sound from the tv. I check the fuse and it is fine, not blown. I opened up the back and took a look at at the LED in the back to see if they're all lite, and they are. I don't think its a conversion problem either. So I'm stubbed. I can hear the tv power on and the power light on the front stays steady on. I visually checked the circuit board and there was nothing apparently wrong. I even used a wooded stick to poke a some IC to see if there i was a crack in any of the solder joints. Anyone have more suggestion that I should look more closely at?

    m1013, would it be visually apparent that the convergence IC's are bad? Like it looks burnt/melted?

  • Kenny Yan Mar 18, 2007

    I did the convergence ic and resistor swap and It still does the same thing no picture. Any else suggestion what it could be?

    the red on light on the front comes on but nothing else. what is my first step?

  • Kyle Porter Feb 29, 2008

    I have the same problem with the same tv but i dont think that its the convergence ic because the the power supply output to the power\deflection P.W.B. is wrong. I read -36V when it should be +14-18V.

I have an Olivia LCD LT23HVX TV., it will not turn on at all. no sound or picture. Can you help?


In other words, your TV is in dead condition now. Check for any blown up fuse on its main power regulator board. You must have to open the TV to access it.

Installed new lamp on my hitachi60v715 no picture or sound


Possible power supply or Lamp Ballast that has instantly blown a fuse.

If no power or lights etc someone has to open and test voltages etc.

If beyond you---have set taken to a shop---a house call is usually a waste of time and money in this situation.

Red light flashing, no picture/sound!!!!


HI, this unit has 3 main fuse links on the main board that may be blown. the fuse links should be check before you move further into the diagnosis stage. once you have checked the fuses and they are still in a working state, this will confirm a power supply board failure. this board provides and regulates the current flow and distribution of it throughout the entire unit. If the fuses are fine and the power supply board is damaged, the green light will come on briefly then, the main control will notice that the power supply is not functioning properly. Once the main control board senses an abnormal current, it will shut down the TV rendering the red light warning. The list of fuses to check are below. Remember, if they are fine and working, the issue will be the power supply board itself and, it will need to be replaced.

FUSE CHECK LIST--

3A 12v- fuse----(242208600623)
SM 3A 125v-fuse----(242208600657)
500 MA-fuse-----(242208611092)

PART NUMBER FOR POWER SUPPLY BOARD

No picture or sound on tv


This sounds like a power supply problem. Check for a blown fuse in the unit. If there is no blown fuse then the power supply might have a shorted or open component in it. Check for the blown fuse first if the fuse is not blown or it can not be fixed by changing the fuse then the next culprit is the power supply, you will have to have a qualified TV technician do this.

I hope this helps
Thank you

No sound no picture


Does any lights come on led on front of set? Does set make any squealing sound when you press power? If not then open and look at power supply board. This is the board that the cord is attached too. look for open fuse, check 2004, 1000, 1300, 1900, etc. See if fuse blown then look for short in pwr. supply.
