GE 7-4836B Alarm Clock AM-FM Radio Battery Wires Replacement

Introduction

This guide involves further disassembly of the clock radio and will require using several different tools and techniques, including using a soldering iron. If you need help on how to use a soldering iron, consult this iFixit guide: How To Solder and Desolder Connections.

Tools:

• High Content Rubbing Alcohol (1)
• Cotton Swabs (1)
• Tweezers (1)
• Phillips #0 Screwdriver (1)
• Flush Wire Cutter (1)
• Portable Soldering Iron (1)
• iFixit 6 Inch Metal Ruler (1)
• Phillips #00 Screwdriver (1)

Step 1: Battery Compartment Cover

Find the battery compartment on the bottom of the clock radio. Using your thumb, push the compartment cover latch toward the battery. With the latch pushed in, pull the compartment cover upward to remove it.

Step 2: Battery

Lift the battery from the compartment. Pull the battery up and gently disconnect it from the battery connector.

Step 3: Screws

Using a Phillips #00 Screwdriver, unscrew the six 12mm screws from around the bottom of the clock radio.

Step 4: LCD Cover

Gently pull the liquid crystal display (LCD) cover off.

Step 5: Clock Radio

Lift the top off. Two gray, plastic internal pieces will fall out when you do this; set them aside.

Step 6: Battery Wires Wire Tie

Using the wire cutters, carefully cut the plastic wire tie.

Step 7: Hot Melt Glue

Follow the wires to their connection points on the printed circuit board (PCB). Two spots will be marked "DC+" and "DC-." Apply rubbing alcohol to a cotton swab and rub it on the hot melt glue for 30 seconds. Reapply alcohol to the hot melt glue. Use tweezers to grab the softened hot melt glue and pull it off the clock radio.

Step 8: Speaker

Grip the speaker. Lift the speaker from the holder.

Step 9: Two Screws

Locate the two 6mm screws on the PCB. Using a Phillips #0 Screwdriver, unscrew the two 6 mm screws from the PCB.

Step 10: Battery Wire Solder Points

Raise the PCB. Using a ruler, measure 1.8 inches from the edge of the PCB to locate the solder point for the DC- battery wire connection. Using a ruler, measure 9 mm from the edge of the PCB to locate the solder point for the DC+ battery wire connection.

Step 11: Battery Wires Removal

Apply the tip of the heated soldering iron to the DC- solder point. Pull the wire from the backside of the PCB at the DC- connection. Apply the tip of the heated soldering iron to the DC+ solder point. Pull the wire from the backside of the PCB at the DC+ connection.

To reassemble your device, follow these instructions in reverse order.
