MOD GUIDE - Universal RGB-to-YPbPr/Component Circuit & Mod [8/24/2014]

[Duo_R]

I'll installing this coming week and post the results.

The one you did had a stock screen ya? Could be the RGB lines being shared with the stock screen.

I just installed the component board in a turbo express. I can't get rid of the jail bars. I tried grounding the two caps to hu6260, shield and component board but got the same results each time.

No, it's modded with a 3.5"LCD. I tapping rgb directly from hu6260. I will see if I can tap rgb from else where.

the TE has a noisy power supply, could be the cause

[turbokon]

Is there a way to reduce the noise?

[Duo_R]

I am sure some caps could help with that. Also is this one lithium battery?

[turbokon]

Yep, this is my original modded TE. I added both shields back and seem to help some but still not as good as the duo. It still beats composite video:)

I finally got a chance to move the component board in my Tg16 to the place you mentioned turbokon(in your pic). It definitely helped with the jail bars. It's not perfect but definitely an improvement. I'm happy with the results.

[turbokon]

Yeah, in my experience, the jail bar fix works best on the duo. I have installed the component board in the duo, TG dock, TG-16, pc-engine and a turbo express. I still need to install the component board in my pce-lt and supergrafx.

[turbokon]

I just installed a board in my pce I had thesteve worked on and it looks great. I didn't have to install the two caps for the jail bars fix as there weren't any. First system I didn't have to do the jail bar fixs.

[Keith Courage]

Hmmm, so it works perfect with no jail bars on a white PCE but not on a US TG16. weird.

Nevertheless good to know.

[turbokon]

No, just seem to be this particular pce only. I did another pce and I couldn't get rid of the jail bars. The only thing I did differently to this pce is that I replaced the three ram chip a while back, the one by the hucard slot and two on the main motherboard. I don't know if replacing these ic's affects the jail bars or not.

[thesteve]

it couldnt be the ram
i just did a CG RGB mod that didnt need the jailbar fix right after fixing turbokon's PCE

My BA6592F's finally got through customs....only to find out I don't have enough rca jacks now >_>.  Need to wait for those to arrive before I can play with this.

[ConHuevos]

Anyone know the impedance for the RGB lines coming off the 6260 by chance?

[thesteve]

they carry 1K loads easy
