Hitachi 53FDX20B Screen and Sound Shut down (Pwr light remains on

Have a 2002 53FDX0B, Picture and sound were working and then it shut down. Powered on and off, everything reset and worked for about 20-30mins and then it happened again. Length of time between resets has shortened to about 1-2 mins. When the screen shuts down the front power light stays on. Removed back of TV, when the problem occurrs there are 4 green LED's and 1 Red that remain lit even though the screen and sound don't work. Can see 3 fuses which appear to be okay. Don't see or hear a fan. TV has 3 color tubes. Any ideas would be helpful

SOURCE: TV PIcture and Sound Shut Down

it would appear its shutting down in a protect mode
its possible its a convergence circuit problem or something on the deflection bd
but it most likley will require some assistance from a tech that is used to working on this type of set
if you noticed when it does come on that the colors are all off line then suspect convergence circuit trouble the the green leds tell you what source is still alive there is a chart in the cabinet that will correspond with each source voltage that can lead you to tracking it down if you know what to look for and have the tools to do so

If you have OSD (on screen display) but no video or sound, you may have a problem with your video input switching or video processor. Either way this could require tracing the signal with an oscilloscope and could get expensive.

You may have a burned video adapter.

A trouble shoting setp you can try is attatching an external display and seeing if that works.
Also try the function F5 key combo. I think that is the ASUS mapping to switch display output.

53FDX20B NO PICTURE AND SOUND


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.

I just experienced the same issue that is described in the previous post. I went through all of the standard trouble shooting modes.
  • Powered down the LCD
  • Switched HDMI cables
  • Checked and reset all connections (even unrelated devices)
I finally got a picture when I made a straight cable connection. I have a sling box attached through my cable box and noticed that the picture was fine when viewed on my PC. I thought it had to be a problem with the LCD. As a last ditch effort I powered off my DVR box, it must have reset the signal from the cable box to the television because everything is working again. I hope this helps you.
