Found a Lynx II from my childhood while clearing out my Dad's house the other week. It's non powering (only tried batteries) and the screen plastic is broken, but I've bought some new caps, power rail replacement parts from yourself and a new soulder/rework station and I'm hoping to get it working again. Absolutely zero experience soldering (or much in the way of electronics) except a few ESP/Arduino projects, but I tore apart an old laptop to practice on and I figured it would be a good project. Wish me luck.
Buenos días. Compré una Lynx para reparar. Todo funcionaba hasta que me equivoqué a la hora de soldar los cables de alimentación y puse positivo en negativo y el negativo en positivo. La consola dejó de funcionar. Creo que el fallo Puede estar en los diodos que están justo al lado de donde van soldado los cables de alimentación. Usted me podría decir cuál es el valor de cada 1 de estos tres diodos?
Don't know the cause just know every dead lynx we get that comes in for repair with a BV screen turns out the screen is dead, zener diode on it always shorted which then shorts power circuit. I mean literally 100% of repairs with BV screens installed are dead in the same way. Don't think there is anything fundamentally wrong with it but it's an observation. Could be they are recommended to install the resistor mod to boost voltage which kills both over time. I think the lower R74 power "fix" is the real danger
@@RetroSix There’s more than one error on the schema. For Lynx 1, the On & OFF buttons are mislabeled. They’ve fixed it in Lynx 2 schema. This is where my above error comes from. Did I say my error? Well not really ;) I didn’t write the Lynx 1 schema.
@@RetroSix I have built this whole circuit on protoboard to explain how the regulation works after watching this video where latching is described well, but regulation half is completely glazed over, and misrepresented as a simple Zener rectifier that couldn’t possibly provide the current for the Lynx. I see now though that you’ve figured it out, and updated info online while leaving the incorrect video here on YT: th-cam.com/video/ICJV00Uswq4/w-d-xo.htmlsi=GOsR3g7pKYzYa9_I
@@RetroSix I visited what I think is your wiki today to find no schematics or scope shots or what have you. I understand if that's due to cost vs donations deficit, however I wonder if you asked yourself why these particular parts consistently fail, and have you probed some points prior to and after the components in question during powerup and power off to look for ringing that could potentially cause the damage? Or does any other vid of yours show that? I have no scope here anymore, and have to wait for a radio club night to get to one. I do have a working Lynx PCB though.

How did it go?
Muito obrigado! Graças a você eu salvei meu Atari Lynx. Thanks!❤
Outstanding

Quel est cette chip que vous remplace ?? Est ce lié un courcircuit ??
A bit of panic on the note about Ben Venn screens, do they put more pressure on the original power circuit? I always thought it was less

Thanks Luke, that's super helpful to know, I'll get in an order in those power packs you've put together. Is the Lynx clean power coming soon?
Mine works, but one side of the screen is darker. Can any one help me.
Unrelated to the video but for your gba shells which screen protector size the orignal or ips size I have a clean screen
Original size. Just bare in mind most reproduction lenses aren't original size they are bit larger but our lenses are correct size
thankyou@@RetroSix
You run the air at nearly 900 degrees Fahrenheit??
TP17 can’t be high when on as the schema says. There’s nowhere for high potential to come from.
From POWER COM. All explained here www.retrosix.wiki/power-circuit-atari-lynx-ii

He wiki explains it all ignoring the schematics. Shows scope probes of it's entire function and operations

Is a new replacement lynx 2 case still in the works?
Yeah
whatup Luke
