PCEGT replace with 3.5inch TFT LCD

[thesteve]

im sure it would be.
4" is an off size as 3.5" and 4.2" are common

[gerard]

I am interested in the mod, are you still taking orders?
Thanks.

[thesteve]

sure, just been busy

Im gonna get this done at some point too.  Just gotta get an express or gt.

I was very tempted by this, but I ultimately decided against it since a) it's extremely rare for me to pick up my Express and play it anyway, AND b) the 3.5" LCD panel that they're using can only be connected via a composite signal, not the raw RGB signal... They tell me it still looks much better than the original (which I assume is analog RGB connected), but you essentially have to switch to the worst video connection method (only slightly better than RF). When/if they figure out how to connect it via RGB, then maybe I'll think about it. Call me picky!

RGB would be much simpler
just finding a display to use it is about impossible

Nightwolf, you don't know what you're missing. It's like night and day. The quality of the new LCD versus the old stock screen is so much better that it makes up for using an "inferior" signal. Check out this video I made for YouTube. Hope you didn't mind thesteve:)

[NightWolve]

Oh wow, you did a full-on video for it! That's cool! Ah, a Filipino guy, eh?

Anyhow, it's definitely interesting and it looks great! To borrow what esteban said, "I don't know if I actually 'need' the LCD Mod for my Express, but I'm beginning to want it!"

Technical inquiry: So if I understand this correctly, the composite sync pin (44) out of the hu6260 chip is disabled by default when it comes to the TurboExpress because it's inherently connected via raw RGB to its native LCD panel? I would guess they disabled it to save power or something and since it wasn't necessary, that correct ?? And as such, the circuit that 'thesteve' designed manages to re-enable composite sync in order to feed that signal to the new LCD panel because that was the easiest path towards achieving a video connection?

a friend of mine has two turbo's one with steve's screen and one without. Not only does the new screen trump the old one by a mile, but steves recap also makes the sound crystal clear and loud. unless you want to keep your's stock (nothing wrong with that), the new screen is a must in my book.

[thesteve]

the stock screen uses pin44 comp sync
by default pin40 lum, pin33 R-Y, pin26 B-Y, and pin20 color burst are disabled as they were not needed.
i enable them

[NightWolve]

Ah, gotcha! Thanks steve, you're very detailed and verbose with your answers...

[Duo_R]

steve where did you get your acrylic?

[thesteve]

i use the acrylic from the new screen.
i cut it to fit

[meka]

Steve are you still offering this mod with the region mod, my pc engine gt is dying even though it has been recapped, with this mod you can actually read text which is good for Japanese RPG's. I'm really wanting this done.
Thanks

[thesteve]

yes pm me
