Detailed Repair Steps

I've been repairing GameBoys in Akihabara for 20 years. Follow this method, take your time.

Step 1: Safe Disassembly

Disassembly most fears damaging other components. Take it slow:

  1. First remove battery cover, take out 2 AAA batteries inside

  3. Gently pry open shell from charging port area with plastic spudger
  4. Disconnect ribbon cable connecting motherboard and LCD screen
  5. Remove 2 screws securing motherboard, remove motherboard

Step 2: Button System Diagnosis

After removing motherboard, inspect button system:

  1. D-pad inspection:

  3. Check rubber pads for aging/cracking
  4. Check contacts for oxidation/wear

  5. Check button caps for wear

  6. A/B button inspection:

  7. A and B buttons
  8. Check rubber pad bumps for wear
  9. Check springs (if present) for failure

  11. Select/Start button inspection:

  12. These buttons are microswitches
  13. Check switches for damage

  14. Check solder joints for cracking

  15. Circuit board inspection:

  16. Check button corresponding contacts for oxidation

Step 3: Rubber Pad Replacement

  11. Ensure rubber pads completely flat

  12. Test: Test button response after installation

Step 4: Contact Repair

If rubber pads fine, may be contact issues:

  1. Check contact wear:
  2. Inspect contacts under magnifying glass for wear

  3. Worn contacts lose conductivity

  4. Clean contacts:

  5. Thoroughly clean with isopropyl alcohol

  6. Gently wipe with pencil eraser (very carefully)

  7. Conductive silver paste repair:

  8. If contacts severely worn
  9. Apply small amount conductive silver paste with toothpick
  10. Apply thin layer on worn areas

  11. Room temperature cure 24 hours

  12. Test: Test conductivity after curing

Step 5: Microswitch Repair

Select/Start buttons are microswitches:

  1. Switch inspection:
  2. Should have crisp click sound when pressed

  3. Measure continuity with multimeter

  4. Switch cleaning:

  5. Spray small amount electronic cleaner

  6. Press repeatedly several times

  1. After repair, test without full assembly first
  2. Connect battery, test all buttons:
  3. D-pad four directions
  4. A/B button press and rebound
  5. Select/Start button response
  6. After test passes, reassemble in reverse disassembly order
  7. Run game testing:
  8. Tetris test D-pad
  9. Pokémon test A/B buttons and menu buttons

Veteran Technician's Advice

After 20 years in Akihabara, customers often ask these questions. I'll answer them one by one.

Why are Game Boy Pocket buttons prone to failure?

Three main reasons. First is rubber aging - 20+ year rubber long hardened losing elasticity. Second is contact oxidation - moisture in air causes oxidation. Third is usage frequency - action games cause significant button wear.

How often need rubber pad replacement?

Depends on usage frequency. Light usage may need replacement after 10 years. Heavy usage may need replacement after 3-5 years. If buttons unresponsive, slow rebound, need forceful pressing, time to replace.

How long conductive silver paste repair lasts?

If done well, lasts 2-5 years. Key is thorough cleaning, silver paste applied thin and even. If applied too thick, easily peels. If cleaning not thorough, poor conductivity.

How to maintain buttons?

I recommend regular cleaning, clean button gaps with cotton swab dipped in isopropyl alcohol. Avoid using in dusty environments. Don't press forcefully with fingernails, use fingertip. Store in dust-proof case when not using long time.

Repair Difficulty

Technical difficulty: ★★★☆☆ (requires careful operation) Tool requirements: ★★★☆☆ (requires some professional tools) Time cost: Approximately 1-3 hours, depends on damage extent Success rate: Very high, above 90%

My Ultimate Advice

After 20 years in Akihabara, I've summarized these key points:

  1. Diagnose before acting, determine if rubber or contact issue
  2. Simple to complex, replace rubber pads first then consider others
  3. Cleaning is key, contacts not cleaned everything wasted
  4. Test comprehensively, each button each direction must be tested
  5. Patience most important, button system very precise

Final thoughts. Buttons are Game Boy Pocket's soul. Without responsive buttons, even best games can't be played. Many customers bring for button repair to continue playing classic games. That Pocket that completed countless games, repaired buttons, can continue adventures.

Remember, you're repairing not just buttons, but countless gaming hours. Take your time, you can do it.
