PCEGT replace with 3.5inch TFT LCD

[compil3r]

Seems the seller admits there's something wrong with *all white* displays. They replied to me asking if I've adjusted the brightness wheel on the side (duh! of course) and also requested a small video of the problem. I will send it, and maybe these end up being defective units...

I just tested all the LCDs with a nomad and they all work. They just don't work with the TE mod.

Damn, mine gives all white with any video source

im working on the issue
when i have a good solution i will post it.
also the vender wants a video of the prob

[compil3r]

Glad I'm not the only one with this weird issue... I will send them the requested video soon, didn't had the time yet, I blame Ys IV english translation

Hey thesteve, do you have a solution for the all white screens yet?

Thanks!!

All white sounds like there is a problem with one of the pins for the HU card slot or a more major problem of a bad trace or Chip somewhere on the board. I'd check the Hu card slot first.  I had to repair an express by swapping in the HU slot from a doner TG16 since a few pins had been bent and destroyed somehow.

Keith, we have the determined that some of the lcd's won't work with the TE's LCD mods. According to thesteve, it's a resolution issue.

Put the screen in a Nomad ;-)

In my case, the problem is that the screen is not working with ANY video source... even if I connect a DVD player, there is only sound and all white video. Is expensive for me to send it back to china, so I just ordered another one from other source, checking that is other brand and seller.

Let's see how it goes!

Ahh I thought it was just the TE having issues. Let me know when you guys find a good replacement.

Wait why can't you just split the CV signal?

If you want to do both LCD and comp vid out to tv, you'll need two tranx, one for each.

[turbokon]

The composite vid out to TV won't be bright enough when using only one transx.

[thesteve]

the reason for 2 tranx is so a shorted output, doesnt kill the internal sig, and to maintain the brightness

[Duo_R]

So your saying a 2nd transistor is used in the circuit?
