How to Fix the Loading Error on Sony CDP-EX355 After Belt Replacement?
Asked Jun 1, 20190 views1 answer
I have a Sony CDP-EX355 CD player, and I recently replaced all three belts. However, I'm now facing a "Loading error" when I test the unit. It can locate the disc and pick it up, but when the reading mechanism starts to close on the disc, it doesn't fully close. The unit attempts this three times before displaying the "Loading error." Occasionally, the reading area does close and reads the disc, but this happens infrequently. I also can't find any sensing lens to clean. Additionally, I discovered a small L-shaped black piece, about 3/4" long, on my carpet after reassembling the unit. I believe it belongs around the front door, so it shouldn't be related to this issue. Thank you for your help!
Troubleshooting the Sony CDP-EX355 "Loading Error"
If you're experiencing a "Loading error" with your Sony CDP-EX355 CD player after replacing the belts, you're not alone. This is a common issue that can arise from various factors. Below, we’ll address the problem step-by-step, providing detailed instructions, troubleshooting tips, and best practices to help you resolve the issue.
Understanding the Problem
The primary symptoms you're describing—where the unit can locate the disc but fails to fully close the reading mechanism—typically suggest issues with the loading mechanism or the optical assembly. Since you've recently replaced the belts, it's crucial to verify that everything is installed correctly.
Step-by-Step Troubleshooting
1. Check Belt Installation
- Inspect Belt Alignment: Ensure that all three belts are correctly aligned and securely fitted on their respective pulleys.
- Clean Pulleys: Use isopropyl alcohol and a lint-free cloth to clean the pulleys where the belts sit. Dirt or residue from old belts can hinder performance.
2. Examine the Loading Mechanism
- Check for Obstructions: Open the CD tray and inspect for any foreign objects or obstructions that may be blocking the mechanism.
- Test the Mechanism: Manually operate the loading mechanism to ensure it moves smoothly without any resistance.

It sounds like you're dealing with a loading error on your Sony CDP-EX355, which can often be traced back to issues with the mechanism or the laser lens. Since you've already replaced the belts, it's a good idea to double-check that they are properly fitted and clean, as any dirt or residue can interfere with the mechanism's operation. Cleaning the pulleys and ensuring everything is free of dust is essential, as even new belts can collect grime.
If the issue persists after cleaning, the laser lens might be the culprit. Sometimes, the laser can become weak or misaligned. You can try cleaning the lens with isopropyl alcohol and a lint-free cloth, being careful to buff it gently. If that doesn’t resolve the problem, using compressed air to blow away any dust from the lens can also help.
If your player still isn't reading discs, it may be time to consider replacing the laser assembly. The part number you mentioned, `KSM-213BFN/M-NP`, is indeed available, and it's often easier to replace the entire optical assembly rather than just the lens. You can find this part online, but availability can vary. It's worth checking multiple sources, as some parts may be discontinued or hard to find.
In your case, if you can't locate the `A3328818A Base Assembly KSM-213BFN`, which includes the lens, you could opt for just the lens assembly instead. Make sure to verify the part numbers before ordering, as even slight variations can affect compatibility. If you need further assistance, service manuals can provide additional guidance on disassembly and part identification.
