If you take the back cover off (and part of the front) you should be able to the cage that holds the lamp. Above that there is a small thermal fuse that occasionally goes out and causes this problem. Quick solution is to repalce with a normal 5amp fuse. Just clip it out and solder the new one in. I would use a pico fuse. Or invest in a replacement thermal fuse from a part store. Part number K5C117BC0003. Goodluck.

Watching tv when the picture went black and now the green on light flashes for 30 times and turns off


A green flashing light for this model of TV indicates that the lamp cover is open on the TV.
  1. Unplug the power cable to the TV.
  2. Remove the 2 retaining screws on the lamp cover with a Phillips type screwdriver.
  3. Remove the lamp door completely from the TV.
  4. Remove the two retaining screws on the lamp case.
  5. Lift up the fixed wire handle of the lamp.
  6. Pull out the handle slowly and remove the lamp case.
  7. Insert the new lamp gently into the correct position. Make sure it is inserted correctly.
  8. Using a manual Phillips screwdriver (Do Not use an electric screwdiver), tighten the screws you removed in
    step 3.
  9. Replace the lamp cover and tighten the cover screws.
  10. Plug in the power cord and turn on the TV. After the initial warmup period (which may take up to several
    seconds for full picture brightness), the TV should operate normally.
If any of the following conditions exist, turn off the TV, unplug the power cord, and repeat steps 1–9 to ensure that the lamp unit and lamp unit
door are installed correctly:
  • The lamp indicator flashes green.
  • No picture
  • Dark picture
  • TV will not turn on
If, after repeating steps 1–10, the problem still exists, call Customer Service at 1-800-631-3811.

Green flashing light - no picture


If the green power light is blinking and you have no picture, then your light bulb has burned out and needs to be replaced. It is not a cheap bulb to replace. If the TV is less than 1 year old it should be covered by the warranty
