PCE image yellow through XRGB-2+ w/region adaptor

[Skykid]

This is weird.

I have an RGB modded briefcase unit (the DB9 connected to the right of the HE unit) and a Euro scart supplied with the mod with two stereo jacks for the sound attached to it.

In the past I used a Eur -> JP adaptor and plugged the scart into my XRGB2+ with no problems, but trying it recently the screen is coming up yellow. I tried on two different setups (LCD and projector) same thing on both.

If I plug the Euro scart into the TV directly, the image is fine (just terrible quality), but if I use the region adaptor with the upscaler, it's yellow (and I have two scart region adaptors and it does the same thing with both.)

Problem is, I know this setup worked fine before, so I'm confused as to why it's suddenly gone weird on me or what I could have missed.

Any ideas?

Thanks for the help folks.

What a weird coincidence. I have a yellow tint problem but I isolated it to the Sync Strike and have posted in that thread to see if anybody have ideas.

I was afraid that something was wrong with the XRGB-3 but running through game in worked fine and also on my XRGB-2+. So I thought maybe it was D in 2. But when I plugged the sync strike into a cga2vga instead of the xrgb it also came up yellow.

Do you have another cheap scaler(like cga2vga) to see if the yellow color appears using it? (to isolate the xrgb from the equation) Does the yellow appear on any other consoles plugged into the xrgb?

Is your yellow like a tint or just straight up everything is yellow color? Maybe we have the same problem on 2 different devices.

Hey man, don't know what a sync strike is tbh.

My SFC runs flawlessly using a JP lead directly into the upscaler, no issues. I don't have another upscaler to test with, but I do have a Saturn with a Euro scart that I can set up and test a little later to see if its isolated to the PCE or is happening through anything using a region adaptor. I know for 100% sure though that both of these consoles worked fine on the setup before, and I know the PCE works fine directly into the TV, and I know the issue isn't isolated to the region adaptor as I've tried two!

So that means the region adaptors are unlikely to both be at fault
The PCE euro scart is working (when direct to the TV)
The upscaler is working (when used with a JP lead directly)

I have no idea what the problem is.

Regarding the yellow, it's just a tint (but a strong one) over everything.

I was using the sync strike as an adaptor to go from SCART to 15 pin dsub to run it on Din2 on the XRGB-3.

if you look at the first pics in this thread you'll see what it is http://shmups.system11.org/viewtopic.php?f=6&t=37285

I guess we'll get more definitive results when you try the Saturn. at least you can then say that the converter is the only thing that is constantly giving you the yellow tint, and if both are doing it at that point then I am also lost.

If I had 2 Sync Strikes then I could see if they both failed at the same time too but I only have the one...

Hmm, in that case the only commonality I can find between the two issues is that a DB9 connector is involved in both. If the saturn comes up fine, it may be that causing the prob. I'll let you know soon as pos.

Check if the blue wire in any of your connectors is broken..

The scart lead works fine when plugged into the TV directly, all colours normal - it's only thru the upscaler that the prob occurs.

Both these suggestions got me curious so I did 2 things. First I checked the scart side of the Sync Strike to see if anything was broken and checked for continuity. The I did the following setups to eliminate the vga connector of the Sync Strike.

The sync strike has RGBS and HV screw terminal blocks and the cga2vga scaler comes with a harness the plugs into the board and comes out with RGBS and HV wires.

so instead of doing sync strike to cga2vga via vga port, I did sync strike via wire harness straight into cga2vga, and I still got yellow tint despite passing the vga port input of cga2vga and output vga port of the sync strike.

So I still stand at the Sync strike but the yellow tint signal happens whether I output through the vga port or the screw block terminals.

So now if we have the same problem despite different devices, what do they have in common? They have the SCART port, and I can't think of anything else.

I'm looking forward to your saturn results.

There is a setting in the XRGB3.. pretty sure it's also in the 2+ (It's been awhile since I had a 2+). Try playing with the A/D level in the options menu. I have taken care of some mild yellowing of whites with that option. How yellow are we talking though?

[Skykid]

Well, now I'm really confused.

I put the Saturn in and it was yellow, then I pushed the scart leads connector side (into the Saturn) firmly and the picture corrected itself. So it's running fine into the upscaler via the scart region adaptor.

I was quite confident that I had checked all connections on the PCE, but set it up again just in-case. No difference. I made sure everything was plugged in securely, no change.

I can't find the exact option Strider mentioned in the menu, but I did run through the options and toggle them but it made no difference.

Totally confused by what's happened here. Looks like I just need to get a Japanese scart lead made up with a DB9 connector and audio leads.

I also tried a genesis through the Sync Strike and still got the yellow. My hope is that it's a loose connector on the female scart input that can be adjusted to make contact again.

Well it sounds like yours is definitely an issue with the unit. My prob is just a mystery.

I still think it's the female side of the scart region adapter in your case. I tried moving the plug around and I got a glimpse of correct color. I did not get it right away again but after some fiddling I found out if I don't put the plug in so deep it works. Must have been pushing it in too much. So go ahead and try not putting the connection in so well and see if that works.

Thanks for all the help and suggestions.

Yeah, I did that exact thing. The trouble is I happen to have 2 region adaptors on hand, both from completely different sources, and the problem is identical. That's why I ruled that piece of kit out of the equation.

See, mystery!

I'd still gamble on the female scart side. Maybe the scart plugs are just a little different. You should probably open the scart female side of the adaptor and the scart male side of the PCE keep them connected(but off) and check for continuity(with a multimeter) on the pins(backside of female scart to backside of male scart matching pin to pin). I'd start on Pins 7 and 5 (blue and blue ground).

SCART is cool because it allows all these signals but it's definitely not made to be constantly plugged/unplugged.

Bumping this with new info:

I dug out my RGB modded N64 and used the exact same official Scart lead I use for the SFC (which works fine with the XRGB2+).

It also displays with a green tint.

Narrowing it down, only mr RGB modded PCE and N64 exhibit this issue, the XRGB2+ plays non-RGB modded consoles such as Saturn, PS2, SFC absolutely fine.

Is this a commonly known issue, and has anyone else got an RGB modded console that does this with the XRGB2+?

Thanks for the help.

What mod are you using with the PC Engine?

edit: and the N64.

Just internal RGB mods - I didn't do either of them so I don't know any more than that, except they both output in green through the upscaler when everything else is fine.

OK, where did you get the mod done?

I've heard this issue before, I think I can fix it/advise a fix. If it's an internal IC there are some extra components that should repair it. I've seen this issue of weird colours on one of my own scalers, I tweaked one commonly recommended mod I found online - you can PM me if you want details. No need to name and shame the modders because I did not see this issue on all equipment and it's only reported by a few people. It's to do with the value of capacitors used.

Note I MAY be wrong, it could be something else, but I've heard this too many times now.

If you are completely missing a colour then it's nothing to do with this, mind. Are you missing a colour?

I'll need to check again to be sure, from memory it's literally just very very green, and it's pretty much the same between both consoles. It could be the absence of red possibly.

I wouldn't be able to name and shame any except the PCE modder, who really did a nice job at a reasonable price so I wouldn't do such a thing anyhow - as for the N64, it was bought as used goods from the store I used to work at, so that one's a mystery.
I'll PM you for the info anyhow. If it turns out to be a relatively easy fix (or one that won't have any negative affects should it not solve the prob) it might be worth a go.

Thanks for the advice!
