SOURCE: WD-52628 Mitsubishi - change inputs

We had the same problem. Luckily, we had a service contract, so it was serviced yesterday. The fix involved the service guy going through a "service menu" and resetting the TV that way. He was not "allowed" to tell me how I can access the service menu, however. I do plan to research this on the internet in case it happens in the future. It is basically a software/computer problem, and unplugging the TV isn't enough to clear it unless the TV is unplugged for "a long time." The technician said the length of time depends on the condition of your capacitors. Anyway, as a temporary fix, he showed me that you can go into the PIP mode. The device toggle for PIP apparently did still work with mine, so I was able to switch the device on the secondary picture and then switch it to primary, then toggle the PIP off. Good luck!

SOURCE: model rs2533sw panel not reseting after being unplugged

I had the same problem (panel would not start up - just flashed one dash after a power outage).

The solution above: pressing the top two buttons for 12 seconds (Power Freeze and Power Cool buttons) reset the panel and everything is working fine now.

Thank You!

SOURCE: Can't find the input/video channel for my Emerson TV

universal remotes are tricky, if you have the pamphlet, often times there are several codes for each brand. you have to try all the emerson codes for your universal even tho the power, volume and channel functions may work with several emerson codes, some of these specialized buttons (like input) may only work on your TV with one specific code.

also, if there are any unlabeled buttons on the universal try them with each new emerson code.

SOURCE: lost remote control for an emerson tv. how do you

I just purchased one of these televisions and it didn't come with a remote. However, a Philips Universal Remote (SRU2103/27)
with a code 0520 works fine. I haven't explored all the codes but I can easily change from tv stations to Video 1 and Video 2 merely by pressing the "Input" button on the remote.

No input message on APRO tv?
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.

When i go to hook up a hdmi cable to my philips flat screen it wont recognize that i have a hdmi plugged into it. so what could that be the tv? the hdmi works with my other tv though
Hi,
This model has 4 HDMI inputs, do you get same problem in each HDMI input?
Did you checked HDMI input with any other video source like dvd player or PS3 etc instead of cable box?
Below are few helpful tips to connect HDMI input..
1. Ensure that your HDMI cable is certified.
2. Press SOURCE on the remote control to switch to another source and then switch back to the HDMI source.
3. Reset the accessory device and the TV.
• Turn on the TV
• Select the HDMI channel
• Turn on the accessory device
4. While the TV and the accessory device are powered on, unplug either end of the HDMI cable and then reinsert the cable.
Try above options and if tv still does not show picture of any video source through HDMI then it seems problem of HDMI processor located on main board, visual check is needed by qualified tech or call Philips if tv is under warranty.
Hope these info will help you.
Thanks.
