    screen is black and no sound

  • subbieinmd Jul 06, 2008

    I put a movie in the DVD player and the sound and picture worked fine. Five minutes later, the screen started fading black from right to left, almost like an eclipse occurred on the screen and went completely black. Sound is fine, no picture. I can't even pull up the main menu screen. It was bought in 1999. Please help!!

Had the same issue.....clean the back of the t.v. of all dust, take out the bulb and blow on it to get the dust off...DO NOT TOUCH THE GLASS PART OF THE BULB! Instructions for removing the bulb begin on page 105 of your owner's manual.

Sounds like your power supply capacitors have failed. Google for Z1234TV and see if you can locate a power supply capacitor repair kit for your model.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

Check the lamp door switch. This switch is really cheaply made. The switch is not available. short rhe wires to fix the problem. then never change the lamp witout unplugging the ac power in the future.

Its most likely an intermittent lamp. The lamp door is located behind the front panel. The front panel can be removed after loosening the two thumb wheels located on either end of the TV in the rear. Observe the light coming from the area around the lamp door. If you see that the light is going out, its the lamp. You can also access the self-diagnosis menu by using the remote control. Start with the TV off. Push the "mute", then the number 5 button, and then the volume down button followed by the power button. When the picture appears, the menu will been visable. If there is a failure with the lamp, or a fan, or many other areas in the TV there will be a number value to the right of the parameter that indicates the number of times the error has occurred.
