+DarkLord Posted November 25, 2020 Share Posted November 25, 2020 Dang it, just got my LynxGD in and was trying to set it up and this.... Never tried to wrangle with a Lynx II before. Is this a common problem and can it be fixed? Does anyone even do Lynx II repairs these days? Thanks. Quote Link to comment Share on other sites More sharing options...
Phill.T Posted November 27, 2020 Share Posted November 27, 2020 Does it work fine with normal carts or another psu? Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted November 28, 2020 Author Share Posted November 28, 2020 Hi. First of all, thanks for the reply. No, it doesn't work with any of my game carts. It gives that same screen. Speaker makes a small "pop" when you turn it on. I tried it with 6 brand new alkaline batteries and directly through the AC adapter. I googled a bit, and found some similar looking posts in other places. It looks like its something to do with the screen, failed on the main PCB? Anyway, that's why I was asking if anyone still did Lynx repairs. I can solder a very *little*, but not good at diagnostics (unless it's obvious). This particular Lynx has been rock solid and has never been abused by me (bought it used probably 4-5 years ago but it's been fine). Thanks, much appreciated.

eightbit Posted November 28, 2020 Share Posted November 28, 2020 Could be just bad capacitors. All of these vintage handhelds (Lynx, Nomad, Game Gear) seem to all need cap replacements at this point. 1 Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted November 28, 2020 Author Share Posted November 28, 2020 I saw some kits for replacing things like that on the Lynx, I think it was Ebay. Thanks for the info. Quote Link to comment Share on other sites More sharing options...

My money would be on caps too. Just make sure you don't rip out traces when you remove the old caps. Most frustrating thing ever. Quote Link to comment Share on other sites More sharing options...

xenomorpher Posted December 1, 2020 Share Posted December 1, 2020 I actually just got a Lynx II recently off eBay to learn how to repair. If you're going to buy capacitors, I'd get them from console5.com instead of eBay. WAY cheaper and they ship out fast. Mark Fixes Stuff on YouTube has a couple good Lynx videos of him replacing capacitors and things so you can at least get an idea of what you're up against if you decide to try it yourself. Please keep us updated though. When I was searching online I noticed a lot of people never gave any updates, which makes troubleshooting that more difficult in the future. Good luck though!

battleman13 Posted December 4, 2020 Share Posted December 4, 2020 It's actually quite rare that caps are the culprits with a lynx unit that won't "fire" beyond the larger power caps (C39 on Lynx 1, C41 on Lynx 2) More likely, the cartridge slot is dirty or the pins are bent on the slot. If it's just a screen issue, you can easily verify by putting a game in and turning the sound up. If it's only the screen, the unit will "play blind" to borrow an arcade game phrase. You'll hear the sounds and music, you can start and play the game, you just can't see whats going on with the screen. If your not hearing volume, and can't play the game "blind" then it's not likely to be just a screen problem. Quote Link to comment Share on other sites More sharing options...
thefred Posted December 9, 2020 Share Posted December 9, 2020 I have a similar issue with one I just purchased. I bought a lynx 2 as not working and wont power on. Contacts were really dirty. Tried to clean them now I get a pop sound from the speakers on power up and the back light comes on. no display or sound on a game that has sound on start up. What is the best way to clean the contacts? Some still look pretty dirty. One thing I noticed when I tried with the new Game Drive in it it does the beep when you hit the button. But it doesn't load the game, it just keeps beeping whenever you hit the button to load the roms. Also looks like the two caps on the top left were replaced. Anyone know the values so I don't have to take apart another of my lynx to check? They look bigger then the rest of the caps, Maybe wrong values? Only thing that looks like it was replaced is those 2 caps. Thanks Quote Link to comment Share on other sites More sharing options...
+karri Posted December 9, 2020 Share Posted December 9, 2020 console5 has good documentation of all the caps and also schematics. It is in their wiki. I usually use isopropyl alcohol for cleaning contacts. Quote Link to comment Share on other sites More sharing options...

I swapped the display with a known good, the ribbon cable also had corrosion on the pins. The other display still didn't work, must be the connector for the cable is damaged as well. The caps I was asking about are the correct values. I'll mess around with it later. I have a bennvenn display in the mail, maybe the pins is uses are fine. Let me know if you have any other suggestions. Thanks for the tips. Quote Link to comment Share on other sites More sharing options...

Did you get Benn's new solderless version or the older solder in one? It doesn't really matter as I believe Benn left the pads on he newer version so you can solder it in place regardless.

It came in the mail today with another elcheapo cart. It may work fine with the issues I am having with this one, when it is held ant an extreme angle I was able to see the insert game message. So it might also have a brightness dial also. I was able to see the ship on the game once. My main issue now is the cartridge slot. It is giving me a hassle to get it to turn on quite a bit. When it turns on, sometimes I can play blind but most of the time I get the music and it wont start the game. I don't think it is a membrane issue, just a communication issue between the cart and system. Does anyone sell lynx 2 cart connectors?

I have on hand 2 of the older solder in versions and just installed one of them into another AA members Lynx II last week and have always been impressed with the results and the soldering work isn't that involved.

Well, I just mean in comparison to much smaller scale stuff like installing an DCDigital, or even installing a McWill into a GG for instance.

I installed a solderless one in another lynx, it only took me about 15 min that I remember, it was simple. I did install the wire for the backlight. Only one wire to solder and it is optional. Only complaint that I had was the wire was short, but I assume it was made that way so it doesn't get pinched. The original one also was hard to plug in. Check out Igor's post, I think it was in gamer articles in this forum. Quote Link to comment Share on other sites More sharing options...
thefred Posted December 10, 2020 Share Posted December 10, 2020 Just a repair update, I installed the solderless screen and I received the insert game message clear right off the bat. I messed with the cart connector a bit and then the game came up clear. At least for a few seconds. I am 99% sure the issues are the cartridge connector. Are there any sources for the connectors any more? Some pins are discolored. I even tried sandpaper to clean them up. I have a few other Lynx with issues, I'm just not the best at desoldering My eyes aren't what they used to be, That is why I am glad about the solderless version of the screen. Luckily it worked out for me on this Lynx. I paid $45 shipped for this one with a game that wouldn't turn on. I cleaned the pins on the game and it works fine on my other lynx. Let me know if anyone has a connector, or source for one. Quote Link to comment Share on other sites More sharing options...

I'm sure I could try and remove the cart slot from one of them. Although them being dead units, I don't know the exact condition of the cart slots on them. Another game you can use for quick check to see if the main logic is at least working, would be Chips Challenge as I believe it will come up fully with the music playing on the title screen once it boots up. Pitfighter is another one that comes up pretty quickly and straight to music and sound effects on its demo mode kicking in. 1 Quote Link to comment Share on other sites More sharing options...

It plays music on boot up and game starts quickly, you can hear the shots firing. If you would be able to get the slot off intact I would be able to resolder it on. I'm just not the best on getting old components off intact. I'll be willing to go that route if you could do it for me, I'm sure your slot must be in better condition then mine.
