Repair case: Philips EPIQ 7C long startup time

September 8, 2021

Latest company case about Repair case: Philips EPIQ 7C long startup time

Failure phenomenon

The Philips EPIQ 7C ultrasound device randomly stops at the Philips logo after it is turned on. The stopping time varies, sometimes more than 5 minutes, sometimes more than 10 minutes or longer, and then continue to start. After the start, the control panel is available and the machine works normally.

 

Fault analysis and troubleshooting

Philips EPIQ 7C models will initialize peripherals during the boot process, and problems with peripherals or cables will cause the boot to slow down.

EPIQ 7C machine peripherals include control panel, hard disk, optical drive, back-end display module, display screen, ECG (electrocardiogram module), etc. The initialization of the interface such as the display screen and ECG does not operate the device, but only initializes the controller, which generally does not slow down.

The back-end display module is connected through the COME module. The board-to-board connection is less likely to have problems. At the same time, the normal output of the picture after startup also shows that the connection has no problem. The control panel, hard disk, and CD-ROM are all connected via cables. Problems with the cables or equipment may slow down the boot.

First, the control panel can be used normally after it is turned on, so the probability of problems is small.

Secondly, the hard disk and the connection line have experienced speed drops. There will be some sudden freezes during the reading process, and the reading speed suddenly drops. In order to solve the problem in the speed drop phenomenon, it has been replaced, but the boot timeout failure phenomenon It still exists, so it can be ruled out.

The only thing left is the optical drive and the connection cable. Unplug the DVD signal cable from the machine, and the machine's boot speed returns to normal. Confirm that the DVD drive cable causes the boot to slow down.

After taking the removed cable to another machine for testing, it is confirmed that the problem is with the cable. The client should be the fault caused by poor contact caused by the bending of the cable.

Therefore, if you encounter such problems on the client side, you can consider disconnecting or replacing the peripherals one by one to test, and locate the problem to quickly solve the problem.
