Asked Jul 27, 20130 views1 answer
I am having trouble with my Coby TV, which I purchased on June 12, 2013. It was working beautifully until today, but now I can't turn it off. I had a Cablevision technician look at it, but they were unable to fix the problem. I would appreciate any advice on what I should do next.
Troubleshooting Your Coby TV Model TFTV4028
If your Coby TV Model TFTV4028 is experiencing issues where the blue light stays on but there is no picture or sound, you are not alone. This is a common problem that can arise due to various reasons including power supply issues, remote control malfunctions, or internal component failures. Below is a comprehensive guide to help you troubleshoot and potentially resolve the issue.
Step 1: Power Cycle Your TV
- Unplug the TV: Disconnect the TV from the wall outlet.
- Wait: Leave it unplugged for 10-15 seconds. This allows any residual power to discharge.
- Plug it Back In: Reconnect the TV to the power source.
- Turn It On: Attempt to power it on using the remote control or the power button on the TV.
Step 2: Check the Remote Control
Sometimes the remote control can be the source of the problem. Follow these steps:
- Replace Batteries: Ensure that the batteries in the remote control are fresh and properly installed.
- Test the Remote: Use your smartphone camera to check if the remote is emitting an infrared signal. Point the remote at the camera and press a button. If you see a light on the camera screen, the remote is functioning.
- Use the TV Buttons: If the remote still does not work, try turning the TV on using the physical power button located on the TV itself.

If your Coby TV model `TFTV4028` is stuck with the blue light on and no picture, it sounds like there might be a deeper issue at play. First, try unplugging the TV from the wall outlet for about 10 to 15 seconds. This can sometimes reset the system and might help it turn back on properly when you plug it back in.
If that doesn’t work, check if there’s any response when you use the remote. Try pressing the Menu or Volume buttons to see if anything appears on the screen. If nothing happens, it’s possible that the TV is stuck in standby mode. You can also try using the power button directly on the TV itself, rather than the remote, to see if that makes a difference.
If you’ve gone through these steps and the blue light remains on without any picture, it may indicate a component failure, which is not uncommon. Issues like a faulty power supply, capacitor failure, or poor solder connections can cause this kind of problem. Given that your TV is still relatively new, it’s a good idea to take advantage of the warranty. You can reach out to Coby Technical Support for assistance. They can help arrange for a technician to come to your home or provide a replacement if necessary. Be sure to have your warranty information handy when you call.
