Only getting a blue screen

Can you tell me how to set this tv for air vs cable. we don't seem to be able to figure that out so all we get is a blue screen and it does not change channels. We got it used so we don't have the user manual and can't find one online

Your remote should have a menu button, four arrow buttons, and a enter button. I you press the menu button it should give you a screen with a number of images across the top. The left and right buttons should move you to different areas. There should be one option that gives you the TV move. Use up and down to select the line which allows you to change from cable to broadcast.

Why is my TV screen PINK?


Have heard of this issue,in most cases while using HDMI cable.Try switching to component cable hookup.(Red/Blue/Green RCA type plugs).This will still give you Hi-Def.(don't forget to get a Red/White cord set for the audio also,unless you get a 5-way cord that does both).

Troubleshooting for maxent mx-42hpt51


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.

I have a apex 32-inch tv model (AT3208S), This tv was connect to a converter box, the other day electric power went out in our area for about 8 mins or less, once the power was back on the tv screen was...


OK, I have one of these TVs, and here's a thought: There's nothing wrong with the TV nor with the cable converter box. Please bear with me. Since I don't know how much you may know about TVs in general and this one in particular, I'm going to assume you know nothing and go from there.

This TV has several different "inputs", which are ways a signal can be transferred from its source to the TV, where it "outputs" the video image. I believe this particular TV has 5 different inputs: In descending order of the quality of the video signal, there're one S-video input (a 4-pin video connector plus red & white audio), three composite video inputs (3 connectors each: yellow video and red/white audio--audio connectors are the same for both s-video and composite), and one coax connector (a single large screw-on connector with a little wire sticking up through the center of it) for a total of five different inputs.

The problem with these Apex TVs is that they always default to the Antenna/coax input first when they are restarted. Most people use the TV to display an input signal (like the cable box or a DVD player) connected either to the S-video or to one of the 3 composite video inputs, not to the coax input, which just displays the channel numbers from 1-125 when it's set to do that (hit the "display" button on your remote to toggle showing the channel numbers for the coax input). If there's no signal coming into the coax input, the screen with appear blue. (If it's blue, it simply means it's not getting a signal via the input to which the TV is currently set. You can turn off the blue screen in the menu settings, but then you'll just get a blank screen. It's probably better just to leave the screen blue; at least you can tell the TV's actually trying to display something that way.)

You have to manually select the proper input by pressing the "video" button either on the remote (lower right corner) or the "video" button directly on the TV (hidden control panel under the middle of the margin around the bottom of the TV screen. You'll have to press on the door, and the whole control panel rolls open to reveal another set of composite inputs and some buttons. The video button is the one farthest to the left.)

Anyhow, by pressing the video buttons, you'll cycle through the various inputs. Assuming your cable converter box is functioning properly, powered on, receiving a signal from the cable company, and connected to the TV via a(n) appropriate wire(s) connected correctly, you should see the output from the cable box on the screen when you cycle through to display the proper video input.

Another possibility: the power outage fried the input to which your cable box was connected on the back of the TV. If that's the case, your cable box would probably also have sustained damage. You can check to see if the various video inputs on the TV are working by connecting different source inputs (like a BluRay/DVD/VCR player, video game console, video camera, etc.) to one of the other inputs and see if you get a picture when the TV is set to the appropriate inputs. (Remember, the "video" button is what selects/changes/cycles through the various video inputs.) One of the sets of inputs went bad on my TV. I just use the other ones.

I have a Polaroid FLM-373B 37 " tv and I get a blue screen with "No Signal" in the top corner. Cant seem to get it to find a cable signal, dvd signal or anything. I have successfully...


That situation clearly indicates that no signal is coming to the set in its present setting. Have you checked to make sure that the tv's input is set on the right input setting. Mine always defaults to "Antenna" which drives me nuts cause I get that big blue screen with "no signal". It seems to do that at the slightest provocation, too. After 5 years, I still have to think twice before checking it. If that is not it, make sure that the cables are plugged in. If that doesn't fix it try another type of input such as HDMI or S video, composite, etc - one that you are not using. Don't forget to switch the input to it. Good luck!

TV shows no input service


You may have to change / adjust the settings on your tv to use cable vs over the air antenna. When power was lost, this setting may have defaulted back to factory (Air / Antenna).

If the cable tuner is damaged, you don't need to write off the tv just yet. Try connecting a VCR to the AV / Component Video jacks, and feed the cable through the VCR (use the vcr as the tuner). Take a few more steps, but you will still be able to use the tv.

Hook up of dvd to tv


hey I think you need to use component cables blue green red from the player to the tv, make sure the blue green red ports are also on the tv, note: red yellow white composite cable will not interchange with blue green red component cable or connection.

simplify- blue green red= component
red white yellow=composite

*wires must match colors on both tv and player inputs.

then set your input on your tv to where you conected the cable.

37" Polaroid LCD TV No signal appears when select channel


I was having same problem, and think I got lucky and found fix.

Try unplugging the TV and waiting 30 seconds, then plug back in.

You will likely get blue screen with "No Signal".

Go to Menu, then scroll down to "Setup". Select "Factory Reset" then hit "Yes."

This did it for me. Wish you all luck.

The set will need some screen voltages adjusted on the power supply board, the VS voltage is marked on the panel inside the set, find the VS test point and the VS adjustment potentiometer. adjust the voltage down at least 10 volts, if your not an experienced person in electronics, get a person that is, there is a high voltage on that board that is dangerous
