D-Sub is usually used for input from a computer, make sure the TV's input source is set to Analogue or Digital (or DTV) as it seems to be set to accept input from a computer, if you do not have a computer connected, then this is why it is complaining of no signal. It will not automatically defer to normal TV without being told to do so, have a look in the manual, or guess around the remote control to change the source of the signal.

TV screen went black, sound is intact, can I fix it?


This sounds like you accidentally hit the input button on your remote. It will either be INPUT or SOURCE on you remote. Turn on your TV and source(cable box) and hit one of those buttons until your picture comes back

My philips flat screen shows no signal and #3 in right hand upper corner just happened when cat knocked over remote no sound


To which model television are you referring? It sounds like you either need to change the input method for the TV or just change to a different channel (2 or 4).

Our HD input suddenly went out.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. .

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 had nothing but problems with my plazma since I bought it. But a couple months ago there was too much red on the screen so I adjusted the red to almost 0 and it was OK not great picture. Then the other...


your main digital and sub digital have failed. incredibly expensive.
there is one attempt that you can make to try (by chance) to save it temporarily.
The digital and sub digital are the two boards in the center of the TV where the input jacks are located.
Carefully disassemble and remove the top layer board (sub digital)- it is connected to the board beneath (digital) by a multi pin connector about 2" in from the left hand side. This is where you problem is. Reseat that connector by removing the board then replacing it.

I have a yamaha htr-5240 receiver. Also have a 6 speaker polk-audio surround set.Center,2 rear,2 front,& the subwoofer. The sub is a psw-250 with no sub out or LFE.I can't figure out what i've done...


First, look at the sub, their should be a switch for "auto" "off" "on" switch it to "on" Then use the Left input on the sub not the right. Left is for mono. Now, if you still dont have any sub, disconnect the RCA at the receiver and touch the end of the RCA, if the sub is on, you will hear a loud humm. Now, go back into the receivers Menu and go into manual setup, find "Audio" and select "Auto". That should do it. If not, put the receiver on "Tuner" and set the sound to 7 channel stereo (I'm not sure if the HTR series has this) or "Adventure" I'm a Yamaha RXV series Dealer so the names may differ. (check in manual for audio surround settings) Anyway, this should let you know if you've got all your spkrs working. Then make sure your TV's external audio is set to "Fixed" (it may be called audio out) depends on TV type. Scroll thru TV's audio menu. If you still have problems post a comment and I will help some more. Hope this helps
