You most likely need to replace the Bulb. It is an easy fix that you can do yourself and will cost you $150 to $200 for the part.

Have a westinghouse lcd tv 50inch model ew50t5kw and would like to know before changing any parts or boards what causes a blue screen no sound or picture


  1. Frank: Verizon. com says try this: Change your VCR's Channel to 3 or 4. Most blue screen issues are caused by the VCR not being set to Channel 3 or 4. If changing the VCR's channel (using the channel buttons on the VCR or from the VCR remote control) did not change your TV screen, go to step 2.
  2. Make sure your TV is not in Video mode. There are three possible ways to change your TV's mode using your TV remote control: 1) Press a Mode button, toggle through the options and select TV, 2) Press a Video button to change your TV's mode from Video to TV or 3) Press Menu, locate Mode or Audio/Video setup and select TV from one of the options. If you are not sure how to change your TV's mode, see your TV's user guide for more information.
  3. Check to make sure your set-top box is plugged in and turned on.
  4. Check to see if other TVs (connected to different outlets) have a blue screen. If they do, contact the Verizon Fiber Solutions Center.

Monitor goes black - green light stays on


My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

We have sound but no picture i have sound but no picture. when you change inputs the word input is doubled up and distorted


There were not much info in the manual but it did suggest trying this.
1st- Unplug for a few minutes and then plug it back in. Or use the reset button look it up in the manual. MANUAL

2nd- Blank screen troubleshooting

• If you're trying to watch TV, change channels or press the ANTENNA button to switch tuners.
• If you're trying to watch something that's playing on a component connected to the TV (like a DVD or a VCR tape), press the TV
button on the remote, then press INPUT until you get to the correct video input channel.
• If you're trying to watch a component (like your DVD player or VCR), make sure the component connected to the TV is turned on.
• If you're trying to watch a component (like your DVD player or VCR), make sure the component is connected correctly.

Post back if non of these ideas work and explain if there are any lights flashing or changing colors on the front where the green light usually is. A fixya rating would be appreciated, thank you for stopping by Fixya!

32 in ILO tv, goes blank


Usually the blue screen is an indication that the video signal to the TV is not present. Most of the new TV's have a video input selection button on the TV and on the remote; try changing the video input selection.
