Thank you for reaching out to us, and we apologize for the delay in responding. We understand that printer issues can be pressing, and we aim to provide thoughtful and precise guidance.

Regarding your issue with the Epson ET-8550 white screen during boot, this problem typically indicates that the printer's firmware has failed to load properly. Normally, when a printer starts, it performs a self-check to verify that all components are working correctly. If any component has an error, the printer usually displays an error code. However, when the screen remains white, it suggests that the firmware could not be initialized.

Possible Causes and Fixes:

1. Firmware Corruption:

   • The firmware may be partially corrupted, preventing the printer from properly booting. In most cases, the traditional firmware update methods (via software or printer menu) won't work because the printer is not able to load even the basic boot instructions.

2. EEPROM Reprogramming:

   • In some instances, the issue can be resolved by directly copying a new firmware file onto the printer's board using an EEPROM programmer. This process involves physically writing the firmware onto the mainboard's memory chip. Since the existing corrupted firmware prevents normal updates, this method bypasses the standard boot process.

3. Mainboard Replacement:

   • If EEPROM programming does not resolve the issue, it may indicate a deeper hardware fault on the mainboard itself, requiring replacement or professional repair.

If you do not have access to an EEPROM programmer or lack the necessary experience with board-level repairs, we recommend sending the mainboard to us for a closer inspection. Our technicians can diagnose the issue more accurately and perform the necessary repairs.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we are not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. Thus, it might take a few weeks before we can evaluate your printer. Our services cover either the whole printer or specific parts, and we provide clear instructions on how to proceed. While our rates may not be the lowest, we encourage exploring self-help through online resources. Start by visiting YouTube or our YouTube channel's homepage (https://youtube.com/@bchtechnologies), and use the search function for relevant videos. YouTube may also suggest helpful videos from other channels.

We truly appreciate your continued support and hope this information helps resolve your issue. Please feel free to reach out if you have any more questions.
