DMS4 E.Z.I Troubleshooting
NOTE: Due to manufacturing error, the initial batch of LED panels shipped out did not have letters marked on the PCB next to each LED. In the case that you have one of these LED panels, the letter to LED mapping is shown above. The DMS4 EZI part which each led/letter corresponds to is as follows:
C: Eject connector
O – X: CDVD DSP clip
D – N: BIOS clip
- One or more BIOS connections (D-N) are showing a bad connection result (RED state) on the E.Z.I. LED panel (shown below) How can I resolve this?
There are three possible solutions:
1) The pins of the BIOS have some surface oxidation and require cleaning. To remove the oxidation from the surface of the BIOS pins, use a light abrasive paper and rub the respective BIOS pins gently until the metal lead pin is shiny. Be sure to clean away any dust or fragments carefully to prevent damage.
2) You have improperly connected the BIOS clip with too much pressure and bent or distorted one of the connection pins of the BIOS clip. You will have to check which pin of the BIOS clip has been damaged and then bend it gently back into shape using fine tweezers.
3) The BIOS clip is not seated properly. Remove the BIOS clip carefully and reconnect it with as little pressure as possible. Ensure all edges of BIOS clip are parallel to PS2 motherboard.
