Rca hdtv dlp screen flashing


Sounds like it could be the power supply. Try changing the brightness of the screen and changing picture modes like movie or standard. If this causes the flashing to change in severity, it will most likely be the power supply board

TV WONT COME ON AND THE LIGHT KEEPS FLASHIN RED AN GREEN ON THE STANDBY BUTTON


  1. If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

  2. If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.

  3. If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.

  4. When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.

  5. If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.

Green light flashing & no picture on Toshiba 40pw13p


There is problem with the lamp. It might need to be replaced. The lamp unit is on the bottom-left side of your TV. Loosen thumb screw (by hand) to take the the lamp unit door. Using a screwdriver, loosen two screws of the lamp unit and carefully pull the lamp unit out.
Put a new lamp in reverse order.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
