That is awesome. Finally someone tried it.

BlueBMW · 02/27/2011, 11:27 PM

Awesome write up! Can you tell us the source of the replacement LCD screen? And also maybe where to find a schematic for that converter PCB?

chop5 · 02/27/2011, 11:33 PM

looks wonderful but no way to just use the rgb as a source? composite av is nice but not as clear.

SignOfZeta · 02/27/2011, 11:36 PM

Wow!

chop5 · 02/27/2011, 11:41 PM

ugh stoopid me,composite is still a thousand times better than the rgb bleeding screen it already has.

turbokon · 02/27/2011, 11:51 PM

Bravo man, this mod is amazing.

NecroPhile · 02/28/2011, 12:37 AM

Dang, what an improvement. Kinda kills the portability putting the converter in the battery compartment, but what the hell - the battery life sucks anyway. Well done.

esteban · 02/28/2011, 03:32 AM

HOLY MOTHER!

nectarsis · 02/28/2011, 03:37 AM

AWESOME. It would be cool if the convertor would be in the main casing to see how much it improves battery life (and RGB as stated). Still Great job

Tatsujin · 02/28/2011, 03:46 AM

very nice, gongrats on that great transplantation

Duo_R · 02/28/2011, 04:03 AM

I had this in the works, congrats on getting it done. Did you get the screen from Dealtime? Also what was your source for mc13077p?

Duo_R · 02/28/2011, 04:05 AM

no doubt, a major improvement on battery life. The old LCD screen is a battery hog.

Platinumfungi · 02/28/2011, 10:54 AM

Great job man

This looks like a nice upgrade! Could you tell us which screen you bought?

Yeah. Did you see what this fellow did?

MotherGunner · 02/28/2011, 04:35 PM

Yea, lol. I was the first to reply.

turbokon · 03/06/2011, 09:52 PM

Would you be able to do a detail write up for those of us interested in doing this?

esteban · 03/07/2011, 12:50 AM

No, not about the silly TFT LCD. I was referring to the fact that he used your name in vain. That's what I'm talking about.

For real.

Keranu · 03/07/2011, 02:01 AM

Now THAT is a hardware modification that even I must applaud to! People have been waiting to see something like this for a long time around here, the results look stunning!

I call it the PCE GT Retina Display.

MotherGunner · 03/07/2011, 10:15 PM

Would be really cool if some kits were available.

Duo_R · 03/07/2011, 10:17 PM

I have an idea what needs to be done, just need a source for rgb to composite board. Any ideas?

TheClash603 · 03/07/2011, 11:21 PM

This new guy is good.

Next mod idea, portable Laseractive.

blueraven · 03/08/2011, 12:26 AM

The screen source is crucial to this repair. Anyway, nice job!

Duo_R · 03/08/2011, 12:54 AM

It's going to be something like this:

_{wayback://ebay.com/itm/3-5-LCD-TFT-Color-Screen-Car-Monitor-DVD-DVR-for-Car-Rear-View-Backup-Camera-/}

There are tons of screens available to use. Just need to figure out the RGB to composite circuit.

yes ,THIS LCD screen is same with my mod.
RGBS signal can look from my post pic.and RGB to AV convert.can search a PS or other NTSC/PAL convert,internal circuit board is just a RGB to AV .
look as below

woshizyt · 03/08/2011, 01:23 AM

the new LCD pannel use Transparent acrylic like below

/913d1e5104b3e246adcc69e4cf9ab4f5.jpg

and black paint like below

a0f61675eeb4c1dcccfba8ffd94c1ab6.jpg

possible these can buy from EBAY.

Duo_R · 03/08/2011, 11:47 AM

What are you saying about the transparent acrylic? Is than needed because you removed the TE cover?

And is that the exact same LCD or just similar? You got yours from ebay?

SignOfZeta · 04/09/2011, 11:10 PM

If you want to see the entirety of the new screen, you're going to need a bigger bezel.

thesteve · 09/23/2011, 04:26 AM

im in the process of basically this mod.
the acrylic from the display i used can be cut down to the size needed, and is already painted.

thesteve · 10/01/2011, 04:55 PM

heres a prelim schematic for a video processing board

phipscube · 10/02/2011, 03:23 PM

This looks great thesteve

I've been looking around for a replacement that is more the original size, 2.6". Its hard to find a 4.3 ratio display at that size (cheaply anyway), but 2.5" can be found quite easily. The only thing that concerns me with the 3.5" mod is the cutting of the original casing that's required, but the lure of the size is leaning me towards giving it a go. I might try and find a dead GT and try the mod on a spare case first.

thesteve · 10/02/2011, 03:41 PM

the cutting is not bad/difficult.
I used a knife and hacksaw blade.

than i used scissors to cut the window that came with the display.

just working on the adapter circuit now, that will be required for any swap.

c0ldb33r · 10/06/2011, 08:18 PM

I'd love it if someone offered this service.

I'd definitely pay for it.

thesteve · 10/06/2011, 09:33 PM

i will be offering it once the video boards are made, but it wont be cheap as its quite involved and the parts are a bit pricey.

c0ldb33r · 10/06/2011, 09:37 PM

then wait until you get a number of preorders, then buy in bulk and save

BlackandBlue · 10/07/2011, 05:12 PM

Man, if I only had a spare TGE case laying around I'd try this. I dont want to hurt mine

Definitely a great idea.

csgx1 · 10/09/2011, 01:44 PM

I'm really excited about this mod and I'd love to do this to my TE. I've been itching to get a PCE LT but I can't justify dropping $500 on one right now. I think a TE screen upgrade is definitely a cheaper and better alternative.

So will the video board be small/thin enough to fit inside and NOT take up the battery compartment like the OP's install?

thesteve · 10/09/2011, 09:56 PM

im still working the bugs out, but my current test board is about the size of a quartar

thesteve · 10/15/2011, 12:30 AM

update

grahf · 10/15/2011, 06:53 AM

I did this about two years ago, and was able to fit the video IC board underneath the controller board. I never finished mounting the LCD though. I was unhappy with the quality of the LCD I had.

thesteve · 10/15/2011, 10:53 PM

do tell.
what issue were you having.

mine works well now.
the board is behind my controller.
the issue i have is the pic is shifted slightly left (I only notice in some games)

i disabled my stock backlight driver as well, to save power and for safety.

stock mine pulled 600mA.
with screen mod and switchless region mod it pulls 390mA for almost twice the battery.

thesteve · 10/16/2011, 03:19 AM

some pics (i have more)

thesteve · 10/21/2011, 02:02 AM

added circuit for component

grahf · 10/21/2011, 11:16 AM

Looks pretty good. Your LCD is a lot nicer looking than the one I had. Probably much higher resolution.

thesteve · 10/21/2011, 08:32 PM

working

thesteve · 10/23/2011, 06:10 AM

perfect

added RGB select

tested and tuned (added sync on green)

phipscube · 10/30/2011, 06:47 AM

Fantastic work thesteve

I'm still in two minds about trying this on my own GT, but that big screen does look great, and kind of how you'd expect it should have been if today's tech was available back in 1990. Will you be producing a thin SMD board like you did for the region mod (and switchless board)? I will be at least interested in one of those as I am still looking at sourcing a drop in replacement LCD screen (in size, so I don't have to cut) that I can combine with your board.

BlueBMW · 10/30/2011, 08:53 AM

We are working on some small video encoder boards
