Controls not working

The projector turns on and off but none of the other buttons work. I have tried using the remote and the buttons on the projector but these are not working. So there is no way to choose a source or view the menu items.

This is apparently a common fault and the unit must be returned to a service centre. Theyll put in a new motherboard for it and unless its under warranty this might actually be more expensive than buying a new unit.

Epson PowerLite 1770W Multimedia Projector. Cannot turn on projector with the power button.

I'm sorry to hear that you're having trouble turning on your Epson PowerLite 1770W Multimedia Projector. Here are a few suggestions you can try:
  1. Check the power source: Ensure that the power cord is securely connected to both the projector and the power outlet. Try plugging the projector into a different outlet to see if that makes a difference. You can also try using a different power cord if available.
  2. Reset the projector: To perform a complete reset, unplug the projector from the power source and disconnect any other cables connected to it. Leave it unplugged for at least 10-15 minutes to allow any residual power to dissipate. Then, plug the projector back in and try turning it on again.
  3. Try a different power button: If the power button on the projector itself is not functioning, try using the power button on the remote control if you have one. Alternatively, check if there are any other buttons or switches on the projector that may serve as a power button.
  4. Contact Epson support: If none of the above steps work, it's recommended to contact Epson customer support or a qualified projector technician for further assistance. They will have more specific knowledge about your projector model and can provide further guidance or arrange for a repair if needed.
Regarding the full lock issue and the remote controller, it's possible that the full lock setting may have affected the remote control functionality as well. If you can get the projector powered on, you can navigate through the menu settings to check and adjust the lock settings accordingly. If you don't have a remote controller, investing in one may be a good option as it can provide additional control options and potentially help with unlocking the projector.
Remember to prioritize your safety while troubleshooting. If you're unsure or uncomfortable performing any of these steps, it's best to seek professional help to avoid any further damage or injury.

  3. Navigate to the "Setup" or "Options" menu using the arrow buttons on the projector.
  4. Look for an option called "Security" or "Password" and select it.

  6. Once you are in the security settings, look for an option to disable or reset the password.
  7. Follow the on-screen instructions to disable or reset the password.
If none of these steps work, you may need to contact Optima customer support for further assistance.

Runco CL-710 cannot be turned on/off by remote control

There are several possible reasons why your Runco CL-710 projector might not be responding to the remote control. Here are a few things you can try:
  1. Make sure that the remote control is properly paired with the projector. Consult the projector's manual for instructions on how to pair the remote control.
  2. Check the batteries in the remote control. If the batteries are low or dead, the remote control may not function properly.
  3. Make sure that there are no obstructions between the remote control and the projector. The remote control uses infrared (IR) signals to communicate with the projector, and these signals can be blocked by objects such as walls or furniture.
  4. Try using a different remote control to see if the problem is with the remote or with the projector.
  5. If none of these steps help, there may be an issue with the projector itself. In this case, you may need to contact Runco customer support for assistance.
I hope this information is helpful! Let me know if you have any other questions.

this can only be solved with remote control or connect the AC cord while pressing the SELECT button on top.
this will cancel the control lock

Could it be possible that the remote needs reconfigured? If none of the buttons work, the it could possibly be that you need to re-enter the TV code back into the remote.
