Call a serviceman. He's saying its likely your power supply and thats certainly much less expensive than a new tv.

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.

The dogs rolled on the remote and the tv went to a blue screen and turned off. Every time you turn the tv on now it is a blue screen and says no signal and turns off after 10 seconds


This sounds as if when the dog rolled on your remote he has pressed the source button so that you are no longer on the TV cahnnel. The TV is looking for a different input eg. AV1/AV2/HDMI etc. This will give you a blue screen & as there is no signal the TV will switch off. Check on the remote for an Input or TV/AV or source button & make sure this is set for the TV signal.

Technika tv lcd 19-907 tuning in to sky in bedroom.


Hi i had the same problem but i have sorted mine now. What i was doing wrong was i wasnt tuning in the analoge channels only the freeview digital ones. To do this you need to first turn your tv on. Then press the "source" button, this will bring up a little menu at the top left hand side. When this menu comes up press the "Programme +" button (the one that you use for changing channels near the volume button) press this until you get up to "TV", when T.V is highlighted just wait 3 secs and it will switch over. You will probably get a blue screen with a no signal message (you are now on analogue) when you get this blue screen press the "tune" button. It will automatically start tuning in all of your channels, at first they will be fuzzy but as it works they will become clearer. Your sky channel will also be tuned in. When mine tuned in it didnt tune them in on the right numbers though, bbc2 was on number 1 etc. If you ever need to use a playstation or something it goes into the scart connection at the side of the t.v and you need to press "source" and go up to "scart". To get back onto the digital channels just press "dtv/dvd".
hope i helped!

Blue screen, no video, but has sound


Did you hit the "input" or "video source" button by mistake on the remote or TV? That would change the input from the one the cable/video source uses. You're getting sound, so it's working......sounds as if the input was maybe changed. I'd hit the input/video source button a few times to go through all the available inputs and see if you get video back.

Channel changes automatically


There are a few things that can cause this. #1 most often cause is either something spilled on the channel button or something wrong with the bezel where the buttons are located causing the button to be pressed all the time. Check the buttons on the tv and make sure none of them are stuck. #2 is a bad button (switch). Replace the switch or the control board. #3 is a short on the wiring harness going from the switch to the mian board. Maybe it's squished against the frame somewhere. #4 would be a bad main board. You will likely have to take this unit to a service centre to have it looked at.
