Component + RGB amp + XRGB
« on: July 17, 2015, 10:41:46 PM »
I edited the entire thread to hopefully make my issue a bit more clear.

To start I will post some pics.

Ok, I have some SS's of each mode (RGB, Component and Composite) exact same settings. Each chip was removed while testing the other one. They are at 1080p upscaled on the XRGB-mini.

RGB


Component


Composite


Youtube video of the Jitter on the component output when the composite cable is unplugged.


The jitter happens at the 8s mark and I think the 21 second mark in the video. It shifts the screen at 21s instead of doing the jitter.




After a week of testing, poking and prodding etc. I finally have a working RGB output. Here are the results.



To me I think the Component chip has a bit cleaner output. I seem to be getting a bit extra red in the RGB amp which makes it seem to blur just a touch.

I may play a bit more with it adjust the color settings on my XRGB-mini to see if I can make it better. I do know one thing, I know my system better now far more than I ever expected to know it. Each trace, each wire and I am just so glad everything works now.

Any more mods go into this machine the next one up will be the Obey chip mod from Turbokon. Also I would like to mention that I am using the Component V2 chip and the RGB amp from Turbokon's website.

He was the one that finally pointed me in the right direction by examining the amp board a little closer. One of the feet on of the chips was not making contact although to the naked eye I could not tell. It took me taking off the 6.3v 470uF cap and testing every trace to figure out where the issue was exactly.

I should mention that I need to have the Composite cable from the Duo plugged in to keep the video signal stable on the Component and RGB output. I do not however need it plugged into anything, just into the Duo and that's it.

Now off to play some games, hells yeah!!

Honestly I just didn't want to read all this mess. I tried to twice and had to restart, then just nit pick through the post. The problem is you are droning on and on and its hard to take out the unnecessary info to sort out what should be read to help you. You are moving from one problem to the next and posting big post about them without giving anyone a chance to reply, on a weekend no less. Patience is a virtue. You post about one problem, give people time to reply. Then move on to the next one.

I will tell you this though. The heat sinks are meant to get hot. I mean, they are after all attached to voltage regulators... Thats why they are called heat sinks. This is why it is ideal to use higher quality caps near them, due to the temp issues. As for the video issues. I am guessing you are splitting RGB from the Hu6260 chip into two different sources at the same time. That will slightly weaken the signal, since you are actively dividing it.

I would have installed a switch to switch the RGB signals coming from the HU6260 to the component and RGB amp. This way you wont be splitting the signals between two devices at once all the time. This way the device you are using will always be getting the best possible signal output from the Hu6260. Preferably a switch that would have enough poles to solder the 5 volt lines to also, to shut power off to whichever part is not being used also.

are you still having video flicker/cutting out issues? If so adjusting the lumu/brightness pot on the component board usually takes care of that.

After a couple of days of tinkering with the system I have found a few things. But I need help with it as I don't understand why it is happening.

I have been running my Duo with all three ports filled. The Composite, the Component and RGB. Everything works as described with the pictures in the first post.

1. RGB shows the Red + blue screen with no green when the Composite connection is connected. But not when it is unplugged.

2. I get no picture from my RGB chip with the Composite connection unplugged.

3. The jittery screen on the component connection is gone when I have the Composite connection connected. But it will jitter when the composite connection is unplugged.

I have no idea why this is happening, any info or ideas are much appreciated.

This is how I have my chips wired up.

Shameless bump....

At the same time I made the thread shorter and easier to read.

Do I need to amp the Sync signal from pin 44 as well or mix it with the green somehow to get the green to show on the screen?


I should mention in the two vids posted below that the Composite cable is plugged into the machine but the other end is not plugged into anything else.
First video here is me testing the Component Video output with and without the Composite cable plugged in.




This second video is of my testing the RGB output with the Composite and Component cable and then without.
