Q: My Candela Gentle YAG device failed to heat up today. I checked the input voltage of the heating rod and it is AC 175V (it was 220V before). What is the reason? Is it the AC distribution board that is faulty? Does it need to be replaced as a whole?
A: Please check the fuse on the AC distribution board, also verify the fuse holder to ensure it has not failed. this is a common problem
Q: My Toshiba Aplio tests positive to PSA-N FE LED (Power supply issue) it looks like the protectors cut off power from the main circuit triggering an abrupt shutdown any one has a concise solution to this problem?
A: The PSA-N FE LED issue on the Toshiba Aplio 500 ultrasound system is typically related to a power supply malfunction, as indicated by the LED alert. This specific issue suggests that the power supply unit’s protectors are cutting off power due to a fault, causing an abrupt shutdown of the machine. Here’s a concise troubleshooting approach:
Steps to Resolve the PSA-N FE LED Power Issue:
- Power Supply Check: First, ensure the main power supply to the unit is stable and within the proper voltage range (typically 100-240V, 50/60 Hz).
- Verify that the facility’s power supply isn’t experiencing voltage fluctuations or surges, as this can trigger the protective circuits.
- Inspect the Power Supply Unit (PSU):
Open the system casing and inspect the PSA-N power supply board.
Look for any obvious signs of damage, such as burnt components, blown fuses, or bulging capacitors.
If any components seem damaged, they should be replaced. If you’re not comfortable with board-level repairs, replacing the entire PSU may be necessary. - Check Internal Cables and Connections:
Ensure all power connections inside the unit are firmly seated. Loose or intermittent connections can cause power issues and trigger protective cutoffs.
Check the connections between the PSA-N and other critical components like the mainboard and the front-end processing unit. - Test the Battery Backup (if applicable):
Some Toshiba Aplio models use a small internal battery for backup power. If this battery is depleted or faulty, it could cause power instability. Test and replace it if necessary. - Cooling and Ventilation:
Overheating can sometimes cause the PSU to shut down as a protective measure. Make sure the system’s ventilation is clear, and the fans are working correctly.
Software and Firmware Update:
In some cases, a power supply issue can be related to firmware bugs. Check if there are any firmware updates available for the Aplio 500 that address power-related issues. - Replacement:
If none of the above steps work, the PSA-N unit may need to be replaced entirely.
Q: I have noticed the mm/s is not adjustable nor does the general setup save the cm/min on restart. What I found out so far is the cm/min can be set from 1 to 3 cm/min. The “paper advance” button is set at 40 cm/min. My goal is to change the default settings to either 50 mm/s or 3 cm/min without having to change the general setup on restart. Trying to find a solution for this goal/problem.
A: Try setting it and then go into Install Options 2 screen and select Store Current to Hospital (assuming the Default Settings is Hospital). That should save the setting.
