Open the back of the TV,and look at the can shaped items on the board that the power cord is hooked to.If any of them have the tops,or bottoms bulged out,they need to be replaced.This should get it working again.I hope this helps.If you have any other questions,please let me know.Thank You very much!

Probably a faulty backlight inverter circuit. This circuit usually has two blown capacitors that will need to be replaced and their failure can sometimes lead to the failure of a capacitor in the low voltage section of the main power supply.

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.

you may need to change the HDMI board in the tv. it will be the hole board the parts are just to small to replace them all to get the HDMI board working again. find a second hand replacement. should be fine with another known working one.

LCD's use a colorful crystal see through display which only visible when light is shining through it. if you have sound and no picture it's always a faulty PSU. Very easy to change out actually.

It sounds to me like it's stuck in service mode.There is a button combination with the remote to return it to normal. I would call Vizio support and they should be able to help you.

I think it's a combination like [volume -], [channel -] and power but I could be wrong.

I have the same problem. The next stage is that the picture won't come on at all and the blue light will constantly blink. I think the light source is bad. Noit sure though.
