Use this guide to replace the Power Supply on the Optoma HD72. An essential part of the Optoma HD72 is the power supply, which changes the alternating current (AC) from the wall outlet into the direct current (DC) needed by the internal circuitry of the projector. The power supply is made to deliver the voltage and current required to run the electronics, lamp, and other parts of the projector.
The following symptoms may indicate a problem or need for replacement with the power supply.
- The projector won’t power on.
- Intermittent power issues: If the projector is randomly turning off or experiencing power fluctuations.
- Flickering image.
- Loud or unusual noises such as a buzzing or humming from the projector.
- Overheating: The power supply might not be supplying the correct amount of voltage.
- Reduced lamp life: Instead of this being a lamp issue, the power supply might be providing additional strain on the projector’s lamp.
A few warnings to consider when dissembling this device:
- Unplug the projector before starting disassembly.
- Avoid touching internal circuitry so as to not damage any sensitive parts.
- Electrostatic may be present and can cause harm. Be sure to wear proper PPE, and let the device be unplugged for at least 5-10 minutes prior to disassembly.
