Question 5v switching regulator

[caxtilteca]

Yeah the Eyoyo screen will need a separate 5v regulator to power it. The small linear reg on the PS2 can't power the PS2 and that screen at the same time. Fortunately the Eyoyo screen doesn't actually need any modding to run on 5v, it has a 5v pad easily accessible from the start. You will have to put some effort into removing all the ports and screwposts tho.

I made a shitty thread for the Eyoyo screen a while ago, it has the 5v location and yPbPr pinout

the screen that i received looks different and before i do anything to it i wanna make sure i do it right, can you help me here

It's hard to see the traces with the lighting, but I'm pretty sure you can just supply 5v to this schotty diode

Ground can be soldered to any of the anchor points around the board

thank you so much, it worked, is my wiring right?i followed your instructions on your other post but i get no signal

Have you set the video output to yPbPr in the BIOS?

in the ps2 yes

Hmm. The blue wire on the PS2 side looks like it might be shorting on the Chroma pad next to it. I should also confirm you've set the screen's input mode to yPbPr/Component and not VGA?

ok i finally got video but wiring the screen this way, the colors look a little weird though,kinda green,idk if you can see it in the picture, you think maybe i need to wire luma and chroma to the screen and ps2 also?

 

[Stitches]

No, luma and chroma are for S-Video. It's possible that this version of the board has a different yPbPr config, but it can only be these 3 pads.

You got video, so Y is in the right spot, maybe try switching R and B around?

Am I doing it right?

The capacitor is wired backwards, the white stripe is meant to be on the ground side. Aside from that, looks good. I'd put another capacitor on the output line as well if you have any spares, just to prevent potential voltage ripple from damaging anything. I know the custom regs thread diagram doesn't show using an output filter cap, but it's a good idea to do it as a preventative measure against voltage ripple. Ginger has quite a tale to tell about not using output filter caps.

will this protection board work to power both the screen and ps2?

Yes, just make sure you use a 8.4v li-ion smart charger with it. A regular DC supply will damage the cells if you try to charge them with it.

is this one good?

That will do

i get no video, i have everything wired correctly, the screen and the ps2 turns on but it just stopped showing video, any advice?

Have you checked if any wires got disconnected?

I think the issue might be this missing pad here your not making a connection.

 

[caxtilteca]

any way i can fix it or connect the red wired from another place?
