hello! Blue screen(bright blue) indicates an absence of signal. If you have "on screen" display characters: menu, channel ##, volume bar, etc, your set might be configured for digital antenna settings, or DTV, "air" mode. Then, you won't be able to get cable channels through. If your "blue screen" is dim and there is no any characters, then your Y-sustain module is bad. Especially, if you have encountered loud "pop" shortly before "blue screen" appeared. Then, it's a major repair with board(s?) replacement. If you can handle that, get back to me in a next session. I will guide yourself "how to". Thanks, Alex.
If there is no click or lights on the front you may have a blown fuse. And usually but not always there is a reason the fuse blew which could be a short in the power supply. If it is an LCD you might have some bulged capacitors in the power suppy which would not allow startup of supply voltages. Get your model number off the back of the set and do a search on Ebay for the power supply and be sure you match the part numbers!

Sounds like a Arcing CRT tube(s)!, You may have a bad color tube!, Set has one red,blue & green tube. If ones at fault, And you heard a POP - more then likely a BAD CRT, The Set is Turning Itself OFF to prevent any more Damage!.... onegeo
Before you buy anything try checking the AUDIO Settings in the Menu of Each Device (Mostly TV) and see if they are set to PCM or BITSTREAM.
HDMI is mostly set to PCM while Optical is generally Bitstream.
The TV may be set to the opposite of what it needs to be.
I would try to get PCM to work first cause it is Better, If not then set what you can to Bitstream and it should pass.
Also check in TV Menu for SOUND OUT or AUDIO OUT or SPEAKERS.
Some TV's have a problem passing Audio through when they are already Outputting them to it's own Speakers!
I Hope this Helps out!

First of all, is your blue "HD" light lit up on the front of your Uverse box?
If yes, then you're in HD
If No, you need to check your connections from Box to TV
1.Those Red-Blue-Green cables are for video only, they don't carry sound and shouldn't be connected to audio outs. Audio needs a seperate cable. Make sure your Red isn't on the audio out which is also red. Make sure your blue and green aren't switched with each other either. Check that at both ends.
2. Try an HDMI cable. It will carry audio and video together and it's one cord instead of 5.
3. What brand/model of TV is it? Is it an older projection TV? The HD tuner might be shot. The individual color tubes commonly fail after a few years.
4. Are you selecting 720p or 1080i from your TV's menu or from the Uverse menu? You'll need to set it through the Uverse box, not the TV.
5.Follow -Menu -Settings -Aspect Ratio to change to 720 or 1080. This should start an autotest which will scramble your picture for about 5 seconds, then bring you back to a menu asking you to keep settings or revert back settings. If you never see that question pop up, then your TV isn't supporting the HD, and you settings will be rolled back automatically. If the question does pop up and you can read it, select "keep settings" and press OK. Your blue HD light should come on the front of the box now.
There is no factory option to stop the box from poping up every time
the signal changes, which is what is happening. It has something
to do with signal strength or the fact that your cable box is not set
up for HD. Call your cable company to get a tech out to check
your signal and set up your cable box because they do not come pre-set
with HD defaults.
