  1. Sega Game Gear Capacitor Replacement, Introduction: шаг 1, изображение 1 из 1
    • After 20+ years, the capacitors in the Sega Game Gear will begin to leak and fail. Replacing these capacitors with new ones can potentially breathe new life into your classic console.

    Danke für diese mega gute Anleitung! Trotzdem würde ich bei den Caps nicht zu Amazon verlinken, da dort fast nur minderwertige Caps aus China angeboten werden die sehr schnell wieder ausfallen!!! Lieber mouser .de!

  2. Sega Game Gear Capacitor Replacement, Remove the Batteries: шаг 2, изображение 1 из 1
    • Pop open the two battery compartment covers on the back of your Game Gear and remove the batteries.

  3. Sega Game Gear Capacitor Replacement, Remove Screws: шаг 3, изображение 1 из 2 Sega Game Gear Capacitor Replacement, Remove Screws: шаг 3, изображение 2 из 2
    • Remove 6 #1 Phillips Head screws. (Red)

    • There is a 7th security screw (Blue), designed to prevent you from opening the device without special tools. The bit you'll need to remove this screw is called a "4.5mm Game Bit." (Also known as the 4.5mm Nutsetter)

    You can manage to remove the ‘nutsetter’ screwyou by pushing strongly BUT carefully against a side tooth at about 45 degrees with a regular tiny screwdriver - I had no other option in Japan; it’s how I managed it. Then I tossed it immediately in the garbage once it was out! No problem operating my GG in the TWENTY FIVE YEARS since!

  4. Sega Game Gear Capacitor Replacement, Remove the Back Case: шаг 4, изображение 1 из 1
    • Carefully lift up the back half of the case. There are cables connected to the back case that will need to be unplugged before the back can be fully removed.

  5. Sega Game Gear Capacitor Replacement, Identify Your "Version": шаг 5, изображение 1 из 3 Sega Game Gear Capacitor Replacement, Identify Your "Version": шаг 5, изображение 2 из 3 Sega Game Gear Capacitor Replacement, Identify Your "Version": шаг 5, изображение 3 из 3
    • To determine the correct number of capacitors, capacitance values, and board layout, you need to identify which board version your Game Gear has.

    • To determine what version you have, look on the right side of the board. You will either have one or two of these ASIC chips.

    • If your Game Gear has two ASIC chips (Fig. 1) there will be two IC's on the right side of the board, and it should be a VA1. If your Game Gear has one ASIC (Fig. 2), it will likely be a VA4, however, there are further possible variations.

    • Look on the left edge of the main board for the VA number (Fig. 3). There are two options, VA1 and VA4, as well as a 7 digit board number.

    I have a board that has 2 chips and no va. It has the number 837-7719-01 then it says IC BD GG Main USA. How do I know what version it is?

    I have the same number as Cody and the model has two ASIC chips like Fig. 1. I would also like to know what version I am working with.

  6. Sega Game Gear Capacitor Replacement, Identify Main Board  Capacitors: шаг 6, изображение 1 из 1
    • Use the board number to determine which capacitor list (see attached PDF) you need for that board: 837-XXXX

    • For Main Boards marked VA1 with 2 ASIC chips, and board numbers 837-7398, 837-7719, & 837-7996: Capacitor List 1

    • For Main Boards marked VA1 with 1 ASIC chip and board numbers 837-8560 & 837-9024: Capacitor List 2

    • For Main Boards marked VA4, 837-9537: Capacitor List 3

    • For Main Boards marked VA4, 837-9537-01: Capacitor List 4

    • For Main Boards marked VA5, 837-10766 or marked 1.71-7923A from the Majeseco Game Gears: Capacitor List 5

    I have a EU model marked VA1 with 1 ASIC. It’s board number is 837-9130.

    It uses the same capacitors as in list 2, with one exception: C4, C11, C14 and C42 are actually 6.3V versions instead of the 16V given in the list. This should not make any difference, though.

    But it seems the EU board numbers differ for whatever reason.

    Thanks for the info and taking the time to note the details! When I get a chance, I’ll try to add that to the existing capacitor list to help anyone with the same board in the future.

    Travis -

    Hi Christian, Just to add to the mix I also have a couple of 837-9130 EU boards with single ASIC however my boards have C4, C11, C14 and C42 as 16V as per list 2.

    Dave Reviews -

    I can confirm this. Same here.

    Florian Schuetz -

    Ho una scheda 837-9130 con un chip ASIC,a quale lista devo fare riferimento?grazie e complimenti per la guida

    Parzival02 - Ответить

    stupid question: where is the capacitor list?

    Im marked VA1 with 1 ASIC chip

    capacitor list 2

    tommyb345 - Ответить

    After the 11 step, there is a 44kb PDF file containing the list.

    Francisco Sánchez -

    I have a board with no Va. The number on the board is 837-8560 made in Japan with only 1 ASIC chip, what version do I have?

  7. Sega Game Gear Capacitor Replacement, Identify Power Board Capacitors: шаг 7, изображение 1 из 1
    • One of the two daughter boards is the power supply. Use the info below to determine which capacitors you need:

    • For Power Board from systems with main boards marked 837-9025 & 837-7720-01: C5 22uF 35v, C11 100uF 25v, C13 820uF 6.3v

    • For Power Boards with main boards marked VA4 837-9538, you need the same capacitors as the list above and an additional C9 10uF 16v

    My EU model’s power board number is 837-9131 and it does not have the additional C9. So again only a different board number.

    Christian Koschmieder - Ответить

    I believe the second bullet point was meant to read "For Power Board from systems with main boards marked 837-9024" not 9025

  8. Sega Game Gear Capacitor Replacement, Audio Board Capacitors: шаг 8, изображение 1 из 1
    • The second daughter board is the audio board. These should all have the same capacitors: C1 100uF 6.3V, C2 100uF 6.3V, C3 100uF 6.3V, C5 47uF 4V, C7 47uF 4V

    Can you tell me the type of ic on L1

  9. Sega Game Gear Capacitor Replacement, Remove the Main Board: шаг 9, изображение 1 из 1
    • Remove 8 Phillips screws and lift the main circuit board out of the case. Be gentle with the screen!

  10. Sega Game Gear Capacitor Replacement, Removing the Old Capacitors: шаг 10, изображение 1 из 3 Sega Game Gear Capacitor Replacement, Removing the Old Capacitors: шаг 10, изображение 2 из 3 Sega Game Gear Capacitor Replacement, Removing the Old Capacitors: шаг 10, изображение 3 из 3
    • The old capacitors are these rectangle shaped components shown here.

    • The factory capacitors are glued down. Using a small pair of needle nose pliers, gently pull up on the capacitor to break it free.

    • The capacitors are surface-mount, so simple melt the solder on each leg and pull it free.

    • Only replace ONE capacitor at a time. This minimizes the chances of you forgetting which ones went where.

  11. Sega Game Gear Capacitor Replacement, Soldering the New Capacitors: шаг 11, изображение 1 из 2 Sega Game Gear Capacitor Replacement, Soldering the New Capacitors: шаг 11, изображение 2 из 2
    • Electrolytic Capacitors such as these are polarized, meaning they have a positive lead and a negative lead. Pay close attention to which leg is where on the old capacitor and be sure to correctly orient the new one

    • Clean up the space where the old capacitor was glued down and tin the pads with fresh solder. Be sure to clean up any leaked substances and corrosion with 99% Isopropyl Alcohol.

    • Bend and clip the leads to a manageable length on your new capacitor and solder it in place. Be sure that when you lay the capacitor down it doesn't extend over any gold circles on the circuit board as these are places that the upper case makes contact with when the Game Gear is assembled

Заключение

To reassemble your device, follow the disassembly instructions in reverse order.

I ma not able to open the pdf file I just take me to another page but everything else it works

Henry roca - Ответить

I just tried it on my computer and it still works for me. Do you have Adobe downloaded on the computer you’re using? If you still can’t get it to work let me know and I’ll try to email you the word document.

Hi Travis,

Thanks for putting this guide together. I am having the same issue as Henry—if I click the View button next to “See Attached PDF” and then click on “Sega Game Gear Capacitor Replacement”, the website returns me to this guide instead of opening the PDF. Tried it in Edge and Chrome. Do you still have another copy of the guide available?

Doc Ferringer - Ответить

It turns out that the link to the PDF that is listed under the Parts section is broken. If you scroll down to the link below the Conclusion section you can download or open the PDF just fine. I’ll leave my question and answer up here in case anyone else has the issue.

Doc Ferringer -

Hey Doc, if you scroll to the bottom of the guide there is a section for attached documents. If you click the “view” button it should take you to the capacitor lists. I don’t know why the other button doesn’t work. If this still doesn’t work let me know and I’d be happy to email you the original document. Good luck with your Game Gear!

Travis -

The power board capacitor list is a bit confusing, i have a va1 9024 but the only similar listed is a 9025, should i use those?
