Why doesn't the Olympus TH4 Power Supply bulb light even when the POWER LED is on?
If the POWER LED is lit but the bulb remains unlit, several factors could be at play. First, the bulb may be nearing the end of its life and needs replacement. Second, a cord plug might not be properly connected, so it's worth checking all connections. Finally, the lamp ON-OFF switch on the hand switch might be set to OFF, so ensure it is set to ON.
What to do if brightness cannot be increased on Olympus TH4?
If you're unable to increase the brightness using the control knob on the power supply unit, it might be disabled because the hand switch is connected. In this case, try increasing the brightness using the brightness control knob on the hand switch instead.
How to fix an Olympus TH4 when the bulb intermittently lights and goes out?
If the bulb intermittently lights and goes out, there are a couple of potential causes. It could be that the bulb is nearly burned out, in which case you should replace it. Alternatively, a cord plug may be improperly connected, so check all connections to ensure they are secure.
