Hi,
Do you see on-screen display or menu in Sanyo DP 42848 screen?
Does tv not show picture in all inputs?
Check for bright white light coming from any vent holes at rear of tv, this will confirm tv has back light or not.
Let me know to diagnose possible cause of problem.
Thanks.

    OK, point flash light on tv screen, observe any faint image there?
    It seems back light is not working in your tv and possible cause would be either bad power supply or back light inverter board.
    Let me know if you are handy with electronics stuff and can check output volts of power supply board with multimeter.
    Thanks.

    OK, no faint image found in screen.
    It seems more serious issue related with main board, please call local tv repairman for visual check of tv to determine what board is causing problem.
    Thanks.

I have a Sanyo Tv Model # DP 42848-00. When I turn on the tv all i see is up in the right hand corner video 1 (I can't change it) then the screen goes black. Can you held me with this problem? Thank...


Hello; The LCD panel is the likely cause of this problem. It can cost as much or more than a new TV. Bad inverter board(s). There are usually one to four of these PC boards. They light up the tiny florescent tubes behind the LCD panel. They are just like a ballast in the old florescent lights. The problem is that the manufacturer that made the LCD panel , also made the inverter boards that are in or on it and are NOT available separately. These are the high voltage power supplies that light up the " backlights behind the screen. The microcomputer in the TV watches these come on. If there is something wrong with one, it will shutdown the set.

How do you clean the screen on a Sanyo DP 42849 LCD T.V.


  • Turn off the TV
  • Apply gently pressure and use a soft lint free cloth to remove smudges and fingerprint. (avoid paper towels/toilet paper/tissues) as they can end up scratching the screen
  • You can use small amounts of distilled water or non-ammonia based cleaning products, do NOTspray directly onto screen instead lightly moisten the cloth and follow up with a dry cloth * ammonia and alcohol based products can often haze the screen often dimming the display
  • There are special products you can purchase that provide anti-static properties to help prevent the dust from accumulating. Check you local electronics outlet if your interested or go to the link below from amazon.
