Question about Hitachi 43FDX15B 43" Rear Projection Television
My 43FDX15B has sparking blue horizontal lines on the screen sometimes. When I touch the back of the TV especially TV antenna input area, the screen becomes clean for a while and starts to have sparking blue lines again. Please help me. Thanks.
Try this procedure:
Adjust the green & blue CRT screens to match the red. Go into your picture menu adjust, turn color all the way down to a black & white picture. Now adjust each CRT screen so that you end up with a true black & white picture. Then adjust each focus control to get a sharp picture, and adjust each CRT focus one at a time for clarity by covering the other two up. Then go back into picture adjust and turn color half way up, you should see a better picture.
If you cannot get the blue & green to even out to a black & white screen you have other problems such as faulty CRT card on back of tube or it could even be that the video IC is faulty. If this is the case, then you may have to get a competent local technician to check the TV and get the necessary parts replaced. It could set you back between $200-$400, depending upon how many components need replacing.
You can also try a hard reset..Unplug all cables, including power from the back of TV. Wait for 4 hrs and reconnect them. Try and see if it works now.
Hope that helps...Should you have any further questions, please feel free to post them here.
