Acer Television AT2703 Flipping through inputs automatically

For the last two days, my television has been skipping through the various video inputs automatically. The delay between switching is anywhere from 10 seconds to immediate. I've checked the input button on the tv and the remote to see if it was stuck. It also has ``rebooted`` itself a few times (tv is on with a green power light, then the power light goes completely off as if there is no power to the tv, then turns red to show it`s off, then green again, and the tv comes back on) Is this a damaged board that can be replaced? I have had the tv for 6 years now and have had no other trouble with it.

Seems like your set now has a poltergeist in it after all these years. If set turns on an doff by itself and works erratically there could be a power supply issue since it supplies the juice for the various areas to do their thing. If PS is messing up, so will other sections of your set.

SOURCE: Remote's menu and input buttons, and television Input button not responding

well the problem sounds like it could be the IR sensor on the tv or somthing in that circut that is failing or the EPROM chip that controls : Vol up/down , Channel up/down , Power on/off ,Menu , Input selection , ect... is failing, thus this will trigger the protection circut to shut the tv down. this kind of a problem only gets worse and can dammage other components if not repaired soon so it will need testing to determine the exact cause

SOURCE: Blinking power light

The TV has developed a fault where the start up procedure cannot be carried out & therefore the TV switches itself back off. You would need to remove the back of the TV & check if there are voltages going to your backlights (24v), are there all the other voltage rails present at start up eg 15v, 5v etc. Check the power supply to see if any of the capacitors are showing signs of stress such as a bulging on the top. If you do not have a multi meter to check voltages or feel comfortable to do this, then it would be best to contact a repair service centre.

Connecting my VCR/DVD combo to Toshiba television


It would be helpful to know what cable your trying to connect, component, S-VIDEO, HDMI, etc. Also the make & model of the combo unit & Toshiba TV. However the basic process is usually the same for most hardware. Make sure the connection to combo unit is "video/audio out" not in and make sure the input for the TV says IN not OUT. Then you need to set the TV to the correct input channel. And then make sure the combo unit is using the correct output... usually this is automatic for component cables but not always.

No picture on this TV. Sound is OK


Hi! Welcome to Fixya!

If you are unable to view video on your television set, the issue may be that the TV's video input selection does not match.

The TV input source must match how the equipment for example DVD is connected to the TV. Every TV is different in the way that the ports are configured on the back of the TV and the menus are presented on the TV screen; however, there are some basic similarities between them.

To correct the issue, use the TV's remote control and change the video input selection. Many newer TVs have an auto-detection system and will automatically detect that something is connected to the various ports on the back of the television. However, some TVs have to be configured manually.
Some common names of the button on the TV remote are:
  • Video Source
  • Video Input
  • TV/VID
Locate the video input menu for their specific TV. Below is an example of the video input menu of a TV.

This example indicates check boxes next to the items that the TV is detecting. Be advised that this menu must match the location on the back of TV where video components are connected.
You may also check if all cables are properly connected.

Thank you.
Keep me posted. :)

What you have done is change the input source. It will toggle through various modes like component, HDMI1, HDMI2, S-video etc., You should take a look behind the tv and see which input you have connected it into(usually HDMI 1 or HDMI2) then keep pressing the input button till it toggles back to that particular input.

Channel skipping in Sony Rear projection KP-EF41 TV


is the channel flipping always happening at set intervals? Or, just randomly? Try replacing the batteries in the remote. If that doesn't work, start looking for other sources of IR(infrared). In some rare cases, direct sunlight on the TV will get it to do strange things.

I am trying to connect my Acer Aspire 7720-6155 to my Panasonic television model number TH-42PX600U. Can you please help


You have 2 outputs on the Acer - S-Video, and VGA.

The TV has both inputs as well. Choose one (I prefer S-Video of the two), and get a cable for that type of connection.

On your TV, select the appropriate input source. You may have to cycle thru all the choices until you find it.

On the laptop, the S-Video should activate automatically, for the VGA, you may have to use the Fn Key plus one of the Functions keys for "Dual Monitor" mode.

By the way, Panasonic has free help for you lucky Viera series owners, try this web page:
