PCEGT replace with 3.5inch TFT LCD

[thesteve]

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.

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.

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.

I'd love it if someone offered this service.

I'd definitely pay for it.

[thesteve]

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.

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

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.

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]

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

update

[grahf]

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]

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.
