In the latest adventure of vintage computing restoration, a dedicated enthusiast takes on the challenge of reviving an Apple PowerBook 165c. This iconic device, which suffered from a dead backlight, damaged plastics, and troubling dark spots on the LCD, presented a formidable task. The restoration process began with a complete disassembly, allowing for a thorough examination and repair of the various issues plaguing this classic machine.

Repairing with Precision

One of the first steps in the restoration journey involved fixing broken plastic standoffs using UV resin, ensuring that the case would fit together properly once reassembled. Alongside this, the case itself received a much-needed cleaning, bringing back some of the original luster to the device. Additionally, the enthusiast tackled the technical side by recapping both the backlight dimmer and inverter boards, a crucial step for reviving the backlight functionality.

The Bright Side

The efforts paid off when the backlight was successfully restored, illuminating the display once more. However, the joy was short-lived as the next phase of the restoration revealed further complications. With a functioning backlight, multiple vertical lines in red, green, and blue became glaringly obvious on the screen, indicating an underlying issue with the LCD panel itself.

Diagnosing the Display Dilemma

In an attempt to resolve the new issue, the enthusiast recapped the LCD controller board, hoping that this would rectify the display lines. Unfortunately, despite these efforts, the lines persisted, suggesting that the LCD panel was failing and would ultimately need to be replaced. This revelation serves as a reminder of the unpredictable nature of vintage electronics repair, where success is often accompanied by unforeseen challenges.

A Work in Progress

While the PowerBook 165c is not fully restored, significant progress has been made. The backlight is operational, the case has been cleaned and reassembled properly, and the overall usability of the device has improved. For now, the machine can function until a suitable replacement display is sourced. This restoration journey emphasizes the patience and persistence required in vintage computing repair, showcasing both the triumphs and the trials of bringing a classic device back to life.

Today I'm tearing into an Apple PowerBook 165c with a dead backlight, damaged plastics, and some suspicious dark spots in the LCD.

This one needed to come completely apart. Along the way I repair a bunch of broken plastic standoffs with UV resin, give the case a much-needed cleaning, and recap both the backlight dimmer and inverter boards.

The good news: the backlight works again!

The bad news: once I can actually SEE the display properly, it becomes obvious that the LCD has another problem — multiple vertical red, green, and blue lines running through the image.

I recap the LCD controller board hoping that will solve it, but unfortunately the lines remain. It looks like the LCD panel itself is failing and will eventually need to be replaced.

So this PowerBook isn't completely restored yet, but it's in much better shape than when I started. The backlight works, the case actually fits together properly again, the plastics cleaned up beautifully, and the machine is usable until I can track down a replacement display.

Sometimes that's just how vintage computer repair goes.

Welcome back to the bench! In this fascinating repair journey, we explore the troubleshooting process of an Icom ID-880H radio that refuses to power on. The radio itself is known for its quality, but this particular unit presents a challenge as it has been non-functional for some time. The repair technician begins the process by injecting power into various points of the radio to diagnose the no-power issue, which is often linked to faulty voltage regulators.

Initial Troubleshooting Steps

The technician starts by preparing the radio for testing, using a current-limited power supply to avoid damage. A blown fusible link is identified as a potential culprit, hinting at a previous misconnection. After confirming the presence of 13.8 volts at certain points, the technician discovers that multiple voltage outputs are missing, prompting a deeper investigation into the internal components, including the critical IC20 voltage regulator.

Identifying the Problematic Components

As the technician probes IC20, it becomes evident that the regulator may be faulty. After temporarily bypassing some resistors, the technician removes the regulator to eliminate it as a source of a short circuit. The tests indicate that the short is no longer present, suggesting that IC20 was indeed the issue. However, subsequent tests reveal that another voltage regulator, IC21, is also problematic, requiring a thorough examination of the circuit.

Digging Deeper into the Circuit

The technician continues the investigation, using a thermal gun to identify overheating components. This reveals that a specific capacitor and a ferrite bead are also potential failures in the power circuit. The meticulous approach of checking each component leads to the discovery that the CPU itself is heating up significantly, indicating a possible short. This discovery raises the stakes, as the CPU is a critical component that could be difficult to replace.

The Dilemma of Repairing the Icom ID-880H

Ultimately, the technician concludes that the CPU is the source of the problem, but unfortunately, Icom does not sell the microprocessor separately. Even if available from third-party sources, the programming required for the CPU is proprietary to Icom, leaving the technician at a standstill. This scenario illustrates the challenges faced in repairing modern electronics, particularly when proprietary components are involved.

As the video wraps up, the technician reflects on the hurdles faced during this repair project, offering insights into the troubleshooting process and the technical challenges of working with complex electronic devices. For those interested in electronics repair, this case serves as a valuable lesson in patience and persistence.
