McWill Posted June 29, 2015 Share Posted June 29, 2015 Can you show a video or some pictures of the mod actually installed and running in a Gamegear - especially the Multisystem mode please! Thanks I try to make a video in the next 2 days. Great job with the GG display! What does the retro-style jumper do? I might wait for the TV Tuner support, because I have one, not that there is any TV signal here anymore though. The retro-style means the 3.5" LCD shows vertical dark lines. The original screen has also vertical dark lines (like horizontal scanlines). Every second pixel has the half brightness. With this option your new LCD looks like an old one, but with high contrast and real colors. BTW: I am still waiting for the ordered 3.5" LCDs to complete the GG mod. I let you know, when the GG mod is ready for shipping. 2 Quote Link to comment Share on other sites More sharing options...

Sleepy Posted July 1, 2015 Share Posted July 1, 2015 (edited) Hi,im fitting my Lynx I with McWills upgrade and have a little problem understanding the manual.In chapter 3 the next to last sentence is:"Solder one wire from VCC (5 Volt) to TP12."I would solder a cable like the red line: But in the pictures from modded Lynx 1 above (i.e. page 18 or page 19) I can´t find that connection. I am wrong?Sleepy Edited July 1, 2015 by Sleepy Quote Link to comment Share on other sites More sharing options...

McWill Posted July 1, 2015 Share Posted July 1, 2015 Hi, im fitting my Lynx I with McWills upgrade and have a little problem understanding the manual. In chapter 3 the next to last sentence is: "Solder one wire from VCC (5 Volt) to TP12." I would solder a cable like the red line: P1090974.JPG But in the pictures from modded Lynx 1 above (i.e. page 18 or page 19) I can´t find that connection. I am wrong? Sleepy You soldered the wire correctly to VCC (left PIN ). He didn't used the VGA out, so he didn't connected the wire from TP12 to VCC. But if you leave the wire from TP12 to VCC, you also must leave the backlight wire. Otherwise your LCD is always OFF. Quote Link to comment Share on other sites More sharing options...
Sleepy Posted July 1, 2015 Share Posted July 1, 2015 (edited) 5 Volt VOLTAGE CHECK: If you removed all the not needed parts, put in a cartridge and turn the LYNX ON. Check pin 1 and 2 of the removed power module on the LYNX board the 5 Volt as you can see in the quick guide. I think it would be a good idea to add this important hint to the quick guide - it takes a while to remember that the lynx doesn´t switch on without a cart... Voltage is fine (4,95V), but before I continue installing the TFT, I´ll add a "5V-mod". Sleepy Edited July 1, 2015 by Sleepy Quote Link to comment Share on other sites More sharing options...

Guitari Posted July 2, 2015 Share Posted July 2, 2015 Fantastic. I'm so up for this! Just need to figure out which of my 15 game gears to mod. Won't be any of the coloured Japanese ones or majesco or kid's gear. Put me down for this mod mcwill! Quote Link to comment Share on other sites More sharing options...
Sleepy Posted July 3, 2015 Share Posted July 3, 2015 (edited) As I mentioned, I´m also doing a 5V-mod. In the 5V-mod R69 is removed.In the LCD-mod R73 is removed.Both resistors build a voltage divider between intern 5V and 9V from power connector: The mid, called "AC connected", is connected to Mikey´s "color/bw"-pin: When I´m doing both mods Mikey´s "color/bw"-pin is open.What´s the task of this pin? Does it matter when it´s midair? EDIT: In a lynx 2 - schematic it´s pulled up to 5V: Source for schematics Sleepy Edited July 3, 2015 by Sleepy Quote Link to comment Share on other sites More sharing options...
Sleepy Posted July 3, 2015 Share Posted July 3, 2015 Both resistors build a voltage divider between intern 5V and 9V from power connector: AC-connected_1.png 5V is wrong; it´s connected to ground. Sleepy Quote Link to comment Share on other sites More sharing options...
Sleepy Posted July 5, 2015 Share Posted July 5, 2015 (edited) Doing both mods, I noticed that my Lynx I switched of itself infrequent during playing. My Idea was that this is caused by removing R69 & R73 and the thereby missing "AC connected"-signal for MIKEY. So I add a 100k pull-up (like some versions of lynx II have) between 5V and the middle of the missing voltage divider as shown in the pic below: It seems to work now; anyway, I played some sessions Gates of Zendocon without any auto-power-off. :-) The new display is awesome! Thanx @McWill for this mod! Sleepy Edited July 5, 2015 by Sleepy 1 Quote Link to comment Share on other sites More sharing options...
Ukaccord Posted July 7, 2015 Share Posted July 7, 2015 Gadgetuk just want to say a big thank you as your YouTube video got me here and the lcd+vga mod is AWSOME and can't wait :) 1 Quote Link to comment Share on other sites More sharing options...
Nismorack Posted July 7, 2015 Share Posted July 7, 2015 Got mine in the mail last week. But I haven't decided which Lynx to build it into. I bought a broken one on a local marketsite for which the seller claimed the screen was broken. Turns out the mainboard is probably fried. So I swapped the mainboard with one from another Lynx (because this one had a pristine shell), and it turns out the screen is in perfect condition. My original old Lynx is fine too apart from a few broken pixels on the screen. HOwever that one was opened up long ago by my dad to fix it and he used some kind of strong glue to attach the rubber grips. Not sure how to remove those. Though I'm getting another Lynx (plus large bag) today so maybe that one will make a good candidate. I only wanted a few more games for my old Lynx, honest.

gsxrboy Posted July 11, 2015 Share Posted July 11, 2015 (edited) Received mine a week or so ago and did my mod tonight. It looks great in vids and pics, but when you see it in the plastic flesh, goodness me it looks fantastic. Many big thanks to McWill for this wonderful mod. I'll look forward to future GG mods too (LCD only done, didn't do VGA) How do we leave +feedback etc here?

McWill Posted July 14, 2015 Share Posted July 14, 2015 The 3.5 LCDs are finally delivered and I began with the first shippings.I'll inform everyone via PM/email who ordered. 2 Quote Link to comment Share on other sites More sharing options...
Sleepy Posted July 15, 2015 Share Posted July 15, 2015 (edited) At the Lynx 1, the TFT´s silver-colored edge is a little bit confusing due to reflections: I used self-adhesive black tape to cover them. The wide edge can remain unmodified; it´s out of sight. Sleepy Edited July 15, 2015 by Sleepy 1 Quote Link to comment Share on other sites More sharing options...
Twoface2 Posted July 15, 2015 Share Posted July 15, 2015 The 3.5 LCDs are finally delivered and I began with the first shippings. I'll inform everyone via PM/email who ordered. If it works with the TV-tuner, I order one! Quote Link to comment Share on other sites More sharing options...
GadgetUK Posted July 15, 2015 Share Posted July 15, 2015 If it works with the TV-tuner, I order one! I don't think it does - read back a page or two. Still very much worth buying one for the clear display and VGA out. Quote Link to comment Share on other sites More sharing options...
Hiddenevil Posted July 15, 2015 Share Posted July 15, 2015 McWill I've sent you a PM as I couldn't find an email address. Found out about this kit today and have to say I'm blown away by the quality of the screen. My Lynx II developed a horizontal line across the lower half of the screen, doesn't stop me from using my Lynx II. But I decided to look in to getting it repaired, only to discovered you can now get new screens! Woohoo! Quote Link to comment Share on other sites More sharing options...
7800fan Posted July 15, 2015 Share Posted July 15, 2015 If it works with the TV-tuner, I order one! It doesn't work. There's little point when you can get a portable TV with modern tuner and about 7" area for under $50. Quote Link to comment Share on other sites More sharing options...
Twoface2 Posted July 16, 2015 Share Posted July 16, 2015 It doesn't work. There's little point when you can get a portable TV with modern tuner and about 7" area for under $50. The point is to have a Game Gear AND a superb screen with A/V input without carrying another TV with you! Quote Link to comment Share on other sites More sharing options...
