Lynx LCD Replacement/VGA-Out by McWill

Recommended Posts

Would love to see the Game Gear VA4 (Majesco) supported.

A few months ago I pulled my childhood game gear out of the attic in my parents house. Fired it up to a burning smell.... decided it was probably bad caps.
So I decided to get a cap kit (which sat here a good 2 or 3 months) and just a few days ago took a crack at changing them out. Wasn't too bad of a job. I have

a decent solder station, and decent soldering skills. I took my time, and tried to do a good clean job. After about an hours worth of effort (spread out across 3

hours as I took some breaks) I had it all recapped and ready for testing.

On my VA4, cap C58 (which I think is cap C70 on VA0/VA1) is a high voltage ceramic cap in the backlight circuit.. she was smoking and arcing on one of the legs.

So that was the cause of my original fault I believe. The unit does play, but it plays blind... no backlight, nothing on the LCD. But it does respond to button presses

and I can hear the sound nice and clear....

Looks like a perfect candidate for a McWill mod and a good chance to put my soldering skills to the test!

Maybe also another reason to buy this really awesome USB microscope. it's cheap, works well... and it's a wayyyy better magnifier than microscope.

I could just as easy get another game gear cheap, recap it and then McWill it.... and might do that. But there is something about keeping that old game gear from my

child hood working!

I have repaired faulty units exhibiting this problem before. Try holding a powerful flashlight on the screen. With a bright light illuminating the LCD from the front you will be able to see a game running.

 

As the LCD is still functional and its just the fluorescent tube that is not working a LED backlight mod will fix your problem.

 

You can remove all the high voltage components associated with the fluorescent tube so you wont have to worry about it shorting again, also you will also have the added benefit of doubling battery life.

Hi all :)

 

I ordered the GG mod from McWill in 2015 and finally got around to applying it. I never owned a GG but I saw one at a friends house (mind blown at the time) and seeing games on it now on a perfect display is quite a treat :grin:

 

The GG was fully recapped (base, audio and power board) before moving on to the LCD replacement.

I have not tested SMS games on it yet but GG games look beautiful and they're a delight to play.

 

One question I have, is the brightness thumbwheel supposed to do something?

 

I followed the 2 ASIC instructions closely which say:

"Solder PIN1 of the thumbwheel to VCC on the GG board. Then solder PIN3 of the thumbwheel to GND on the GG board"

 

Thanks for this lovely product and for the detailed instructions!

I'm attaching some pictures of the mod below.

For the latest firmware you have to send it to my address and I will do the firmware update. Then please send PM ;-)

 

Is there a 'log' or something available of firmware versions? Improvements and such, so that I can decide if it is worth the hassle of doing the upgrade?

Hello everyone just wanted to say thanks to McWill for creating these awesome mods as I have one of each from him directly! Just wanted to also verify if the screen tearing issue is just something that is a byproduct of this LCD screen? Specifically for the Game Gear on VGA output it seems to tear quite a but so not sure if there was any way to try and mitigate this. The Lynx on the other hand seems fine with very little tearing. Thanks again!

For those with a VGA out mod, is there a way to hook that up to an old-school CRT? I tried a VGA to component converter, but the output was too high @ 480p. I've tried a VGA to component cable adapter, which didn't work. I think maybe the Retrotek VGACTV1 does it properly, but I don't feel like spending 75-80 dollars.

 

I know there are VGA to S-Video/Composite adapter cables, for use on laptops. However, I'm not sure if those are designed to receive an S-Video signal from the device? I don't think they down-convert at all.

I've also seen these things, which are powered, and may actually work....

Any ideas?

I've had my McWill screen since 2016, but only just got around to recapping my Lynx 2 and installing it.

What can I say, it's amazing.

Combined with the SD card from SainT, I'm in Lynx heaven. :-D

 

Thanks so much, McWill. What a fantastic product!

Does anyone on here offer an install service for this screen by chance? My hands just aren't what they used to be and I have 2 systems that I'd love to upgrade.

If you are in the US, try Video Game Repair on Facebook (https://www.facebook.com/vintagevgr/). He is currently doing the McWill install on my Lynx I and II.

Thanks folks. I'm in the US, but I'm open to options regarding where it's done. It's a Lynx 2 that I'm needing the screen installed on at this point (2 of them actually.) I'll check out the Video Game Repair on Facebook and see if I can go that route. Much appreciated!

The answer to your question lies in the question itself (phrased differently of course) - "Does anyone know who I can get to install a McWill screen for me?" The answer: McWill himself. International shipping may be intimidating, but don't let it, and now it can be mostly tracked at USPS both going and coming. Plus - if you can keep the weight under 2 pounds and don't mind limited/no tracking - International 1st class is quite cheap. I am sure there are many fine vendors out here though, but the quality of McWill's workmanship can not be bested(actual customer here - not a paid spokesperson). Plus, its a nice conversation piece :-D to be able to say (or at least believe) that your McWill screen replacement was done by McWill himself.

More excellent info, thank you again!

With the thumbwheel you can switch between VGA and internal 3.5" LCD on the GG. You don't need to wire VCC and GND to the thumbwheel, if you don't use VGA out.

 

 

Sounds good! I was wondering about how to switch back and forth.

hey just asking for some input, I've had a Lynx 1 and and a Lynx 2 modded by a local service. Got them both back and they well to be honest blew my mind they are just amazing. The screen is just gobsmackingly brilliant.

 

However, the Lynx 1 also had a VGA port added and for the life of me I can't get it to work - I'm chatting to the tech who did it and i think i'll be returning it but has anyone experienced this.

 

- with the VGA cable attached the Lynx does not switch on, it does not matter what position the brightness wheel is at. there is no sound or anything.

- if the VGA cable is attached while the device is running then unplugged after a bit it reboots.

- have tried two different VGA cables and displays (a tele and a monitor).

- it does the same thing as above even with the cable plugged in and the other end not connected to anything.

 

Now, to me it feels like a short or something not sure.
