Sounds like the vertical deflection has blanked the tubes for protection. Check the solder on the vertical output IC for bad solder joints

Projection TV. DVD works. Cable often seems, "untuned". Static & un-fine-tuned sound of channel with black screen. Then, later, it will come on just fine. Sometimes, will go back to untuned status.


I would suspect your cable box first. I would unplug the power cable from your cable box and wait 60 seconds. Plug it back in and try to watch cable tv. I would also make sure the coaxial cable going from the wall to your cable box is connected properly. I would also make sure the cable going from the cable box to the tv is connected properly. Test your tv and see if it works correctly when you watch cable. If this fixes the issue you are good to go.
  • If this makes no difference use a set of new cables if you have them.
  • If this does not work then call your cable company. They may have to replace your cable box.

No picture good sound good lamp can change channel


I have the exact same TV and have had the exact same problem. I talked to a TV repairman who said it has to be my deflection board. I just found this out today so I am looking all over the web for a deflection board. I hope this helps! Tyson

Can't get rid of black box


You have your TV in the "Teletext" mode. Go into the TV menu and select the closed-captioning menu and turn off the text function. What you are seeing is the result of the TV's captioning circuit latching onto a false text pilot signal and then throwing up the black box on the screen.

Sound but no picture


Good Day, gary;
It sounds like the TV has a bad formatter board. This board is not available from the factory, it must be repaired. Tile or block pattern with no video or OSD. Check D8F00 and D8F01 part # 264P828010, also check C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002). Remember FMT PCB is not available. Good Luck, Big Irish.
