430 rg pixilating ??

[geb]

Hi all:

My 430rg which i modified with NOZKT a few months back has started to give me problems with my signal. The picture is pixilating and sound chirping quite often.(To often to use) Cable is good as I modded another 430 and it is running no problem on the same Cable Connection. I have reflashed the reciever numerous times, erasing the flash 5 to 10 times then rewriting. I have erased sectors seperatly (31 sectors) and still the same pixilating problem. It is not the HU card as it is running now. Anyone with any ideas?
Does anyone know what the little knob on the tin box at the rear of the reciever is actually for? (Located at the rear-Satellite in/out to tv box).
Thanks in advance.
Special appreciation to all the moderators and specialists in the satellite testing field - keep up the great work.

I have a modded 430 and mine does the same thing especially when I am on my locals and viewing the guide in the 500s. It is very slow and makes the chirping noise when viewing the guide. I am using the 0039 0204 flash. What flash do you have?

[m5runner]

use the little black knob to udjust the picture. that should solve the problem.

Thanks fellows:

Quickone are you referring to the software revision in the reciever? The nozkt re-flash was with pcr20 and the 430a_2_04 the chirping/pixalating was extremely noticeable in the 500's, I have no locals programmed into the card.

m5runner, the black knob, i have tried adjusting it a little but did not want to fool to much with it. So what happens if i turn it to far one way or another? Will it only affect the picture? I thought I noticed it got worse when I went one way but was not sure.

I will put it back into use and try fooling with the black knob.

thanks again

Little black probably isn't going to fix pixelation, it is to tune the output channel and pixelation is a receiver problem caused way before the TV out, try it but I doubt it's going to help.
What is your signal strength?? If it is 75 or so, then the tuner section is probably going bad, an unfortunate weakness in the 430/431 receivers.

[m5runner]

the little black knob is nothing but a variable capacitor. common sense would tell u if it gets worse going one way, reverse the process. if you are using coax output, try audio video out and see if that helps even though i doubt it will. try it on another tv and see if it has the same problem. 75% signal is still good. i put a dish up around a damn near jungle and i only got 72% tops and it still works just as good as my 98-100% at home. let me know if you get the same results when trying it on another tv.

goto menu then system setup then goto upgrades. that will tell you the exact software revision you are using. I would try another bin too, see if that makes a difference too, I maybe crazy, but I have noticed with another bin I didn;t experince that problem as much.

Hi fellows:

Signal strenth is about 92% and I know it is not the cable/lnb or anything pertaining to the input from the signal. It is not the bin or card as the same cloned cards are running on all my other recievers.
m5runnner, you answered my question as to what the black knob was and yes common sense would tell you if it gets worse one way then go the other, but also common sense tells you that if it is an output problem like skinerd mentions then the problem is in the reciever most likely, which is why I tried reflashing numerous times. Switching from coax to video does not make no difference. It is not the tv as I have switched tv's and a freshly modded reciever is working like a charm. Same nozkt flash same bin same id.
Skinerd so if it is in the tuner section, which i will presume now as things seem to relate directly to the reciever, where is that area? is it under the tin cap on the satellite in connection? I am willing to sacrifice the reciever in trying to get it to work if there is something I can try or any tests which I can apply.
And by the way any time I need info on nozkt especially, skinerd is the name I search.
lol
Keep up the great work.

Thanks again for the input fellows. If I come across anything of value I will be sure to post.

Thanks again to all moderators and members who post such valued information. :)

[skinerd]

the tuner/ sat link section is inside and close to the tin box section. some difficult stuff to trouble shoot, especially since it works, just doesn't work right.

[m5runner]

what can i say, you can follow whoever you want...free country right? its not all the time the person with all the posts etc has the right answer. this is why this thing is called testing...you test, you test, YOU TEST and when all else fails, you test. read your flash again and check the location of the video byte and see if that changed.

I also have a 430 with a searching problem, I have reflashed with every flash available, still searching.
I have the data sheets for the conex 24108 and 24110 chips used in the 430, if any one wants to see them, these are extemely complicated, programmable chips, and if one fails you will be searching until it is repaired, and you can't just buy a new one and stick it in as they require programming, and where are you going to get that.
And as far as removing one from another 430, good luck, these are extremely small footprint chips.

[m5runner]

post the data sheet. i would like to look at it.

Here is one.........I reduced the file size for the other, it's posted below

Other cx chip datasheet.............

Other cx chip datasheet.............

Hey Skinerd great post been looking for that for a long time now, I got a 431 that has this problem for a year now, tired everything, even a new lnb chip, and still 0 signal, I am at
The point where I will try anything now, right now got nothing to lose ,so do you really think changing that small chip could work? If so I’ll do it. I know its micro surgery but
I have to figure this out its driving me Mad.

Thanks

[skinerd]

I have no idea, those are just too small and too much trouble for me to mess with, my luck changing them, it still would not work and I wasted all that time and effort, I wish I knew a good way to trouble shoot them., but I just don't.
Look at those data sheets, complicated little chips those things are............

Did you see my post about a guy changing the crystal and getting his going??....lucked out I think, but worth a shot, it's cheap and easy to try....

How do I find that post for details, you have so many posts to search through all 1500+ posts .

Thanks again.

[skinerd]

All it said was the guy changed the crystal and his started working, that's it.....
I have one I may try that one myself.....no harm in trying......
The crystal is inside the sat in box....

Thanks Skinerd I'll give it a try

Alright then m5runner I agree it is all testing and you r right it is not always the guy with the most posts that is right. I just stated that skinerd is pretty darn good with nozkt and probably lotsa other stuff to. So you mention reading the flash and checking the video byte, well i am game for that also if you can shed some light on what program i should read the flash with and if the byte is at a certain line, what line it might be. My guess is I would be using jkeys to read the flash and ??? to read. But this is a guess--i am a far cry from a electronic wizard but i wasn't just dropped off the apple cart either.lol
Skinerd thanks for the input on the tuner section. I could only get the cx24108 pdf to open and the other errored out. Just glimpsing at the sheets sorta makes me wonder how long this reciever will collect dust. lol I may try the crystal in the tin tub if i can find where to order it, will search on that.
Jimbo427, well i can't offer you any advice lol but if you find something be sure to post as i will if i ever come up with anything. There are lotsa good moderators and testers such as m5runner and skinerd who are always willing to give advice. And realisticly if we knew the answer, would we post the question. lol

Once again thanks fellows.

[skinerd]

I just tried to open the 24110 pdf from here and it opened up ok.
Yes, jkeys is what reads the eeprom with then open it with any hex editor, or just edit it directly in jkeys, I have no idea what the "video byte" is tho........may just load another good eeprom file to it....
