I have optoma hd803 error no signal all input connected but still no signal how to reset the device

If your APRO 19" LCD TV is displaying a "No input" message, it usually means that the TV is not receiving any signal from the connected source. Here are a few steps you can take to troubleshoot the issue:

1. Check the input source: Ensure that the correct input source is selected on your TV. Use the TV remote or the buttons on the TV itself to cycle through the available input options (e.g., HDMI, VGA, AV, etc.). Make sure you select the input corresponding to the device you have connected (e.g., a cable box, DVD player, game console, etc.).
2. Verify the connection: Ensure that the cables connecting the TV to the input source are securely plugged in on both ends. If you are using HDMI, VGA, or AV cables, check that they are properly connected to both the TV and the source device. Also, make sure that the source device is powered on and transmitting a signal.
3. Try a different input/source: If you have multiple input sources available, try connecting a different device to the TV to see if it receives a signal. This will help determine if the issue is specific to a particular input or if it persists across different sources.
4. Test the source device: If possible, connect the source device to a different TV or display to confirm if it is outputting a signal properly. This will help isolate whether the issue lies with the TV or the source device.
5. Restart the TV and source device: Power off both the TV and the source device, unplug them from the power source, and wait for a few minutes. Then, plug them back in and power them on again. This can help reset any temporary issues that may be affecting the signal.
6. Factory reset the TV: If none of the above steps resolve the issue, you may consider performing a factory reset on your TV. Please note that a factory reset will erase any customized settings on the TV, so make sure to check the user manual or contact APRO customer support for instructions specific to your model.

If the problem persists after trying these troubleshooting steps, it may be best to contact APRO customer support or consult a qualified technician for further assistance. They will have more specific knowledge about your TV model and can provide further guidance or arrange for a repair if needed.

There is a source lock and source button I would unlock source lock button and the push source button until you get to your hdmi input you are using. You also may just plug in one input first and once you get the input right play with the multiple hdmis

Go into projectors inputs and assign it to the correct input. There's multiple choices

You need a tuner to tune in the tv channels. use a vcr that way you can change your channels

Go into menu settings, look for a menu item that has to do with screen size and orientation. You'll be looking for the option to rotate the image for mounting the projector upside down on a ceiling mount.

Use the remote control to change the input setting from VGA to DVI.

switch your lap top first and the projector second----check input is assigned to computer-------press fn key with conjunction of f4 or f5 or f6 or f8.

blimey, these dv10s seem to suffer big from this problem.
check air filters,fans running.
if no input pj may shutdown by itself anyway
try connecting an input signal to see if pj keeps running

Hi, Possibly either of 2 reasons: 1. Your player is not sending any signal to the Optima meaning it is the one in question and not the projector; or 2. Your Optima lost its input signal, go through the signal source selection menu, try manual selection & set it to where your source/player is connected. Hope this works out for you, if not pls post again . Good luck and kind regards.
