Picture garbled..

[DJmistral]

I'm getting something similar to signal losses on my 430RG modded receiver. The picture gets garbled and the sound clips every couple of minutes. Something that normally might happen during a thunderstorm, only its sunny & clear outside.

To add confusion to it, my 420 modded is working just fine. Both receivers are using the same ACT script, and hooked up to the same dish w/ dual LNB.

Some people have suggest the EEPROM on the 430 may be corrupted, but it was working fine for the last 3 weeks. Any ideas?

[skinerd]

Flashes and eeprom both can become corrupted after modding,
relash the nozkt bin and reload the original eeprom bin.

Do what RayJ said and swap the cards and see what happens first ...

4x

[DJmistral]

Swapped the cards.. its still misbehaving..

So I guess the only way now is to reprogram the flash?

[skinerd]

you have already done it once, should not be hard to do it again.

Reload original eeprom file too, you did save it didn't you??

If not I can send you one.

I have been having the same problem with my IRD; only it is not modded. I have used activation and mili's private 3M and it is doing this every once in a while. The picture breaks up like in a thunderstorm and no sound momentarily. Thought it was just me!:confused:

[DJmistral]

Rebel: So what did you do about it?

[Rebel]

Nothing, yet. This has been going on for several days. I really thought it was weather related; but like you said the sun is shining. It doesn't do it very often; it will go for awhile just fine and then it will start doing it again. I think I can live with it.

[skinerd]

check your signal strength with the on screen meter, dishes do get mis-aligned, due to wind and weather and neighbors kids.

[DJmistral]

I have a dual LNB dish and the other receiver is working A.OK

Signal meter is about 86 to 92

Guess I have no choice but to try the MOD again

[skinerd]

did you try swapping positions of the receivers?? lnb's fail too, and a dual lnb is just that 2 lnb's. one can fail while the other functions perfectly.

[DJmistral]

Swapped receivers.. still freezing in the 430, 420 is working fine.

Re-programmed the mod into the 430, still freezing.

Could it be the EEPROM? If so, I'm in trouble cause I never saved the EEPROM from the 430, I only made a backup of the FLASH.

So now what?

[skinerd]

I can send you an eeprom file, and you could try that.

[DJmistral]

Skinerd: Check your PM.

[DJmistral]

Welp.. reloaded the EEPROM.. still freezing.. I'm running out of ideas here guys.. anymore suggestions?

[skinerd]

Another possibility is that your lnb power supply in the receiver is failing. Or a possible loose or broked solder joint in the lnb power supply..

[DJmistral]

Well it can't be an LNB problem cause I've swapped the receivers, so now the 430 is running off the LNB that my 420 was before.

OK.. I'm gonna try to load the original flash back in without the nozkt. But if that still doesn't work, I'm all out ideas why its acting up.

[skinerd]

the power suply is in the receiver, it is a lnbp15sp chip. I have seen many of these failed, your's may be going out or loose or bad connection.

[DJmistral]

How would test the LNB chip?

[jetsgone]

Check your cable. Are you using RG6 or RG59?

I had this exact same problem when using RG59 instead of RG6 cable.

It was one of those things that totally happened out of the blue, got progressively worse, then resulted in the "Searching for Sat signal" message.

As soon as I replaced the cable run with RG6 all was good:cool:

It appearantly works most of the time, so would be hard to test.

Did you check the cable out as suggested in the previous post?? The 430RG's power to the lnb is lower than other models, and that might be a solution, RG6 cable is larger and better shielded than RG59.

[DJmistral]

I'm using an RG6 cable.

Reloaded the original FLASH on there, still nothing, so I guess this problem isn't related to my noZKT mod.

I'm considering calling RCA tech support! Hehehe.. you think they'd ask any questions? I'm from Canada with no subscription! :D

Anybody know someone in Canada that can do electrical repairs on a receiver? :S

[jetsgone]

Can you take the receiver to a friend's place and hook it up to see what happens?

Can you run a new piece of cable just to be sure it is not the cable?

If all else fails check the yellow pages under satellite or tv repair. You never know, there might be someone listed.

I've been watching mine since you mentioned this. I haven't noticed anything unusual since I did my mod. This is the most difficult soldering mod I've ever done. The wires kept snapping off while I moved the board around the desk. At the very end, one snapped again while I was reassembling the case. I ran wires to a pin header in order to use my original jtag device. And I find I dislike the menu system on the 430. I prefer the 420. Oh well.

I'd suspect your problem to be in the cabling to the lnb. Have you done a ohm's test on both?

[Rebel]

Just wanted to let you know we cut down a very small limb in front of our dish and the signal strength went from 62 to 99. This was a fast growing limb. When the wind blew we got a bad picture. So simple!!!!!!:)

[jetsgone]

Doh!!!!

It's amazingly (and most of the time painfully) easy to overlook the obvious!

I'm glad it worked out for you. I think there were some good ideas thrown around in this thread. I know I'm going to save it for future reference.

[DJmistral]

I really don't think that the problem is with the dish or the cables running to the LNBs. I'll describe what has happened so far:

430RG was setup downstairs, the 420 was setup upstairs.

Both are running the same act script, same camID, both are noZKT modded.

As soon as the 430 started acting up, I rebooted, no change.

Swapped & rewrote the cards, 430 is still acting up. This means the problem isn't within the card.

Swapped the receivers, so now the 420 is setup downstairs and 430 upstairs. The 420 works perfectly fine downstairs, but the 430 is acting up still. This means there's nothing wrong with cables running to the dish and both LNBs.

Reprogrammed the EEPROM and replaced the FLASH back to original state, (removed noZKT mod). Still acting up! This means the problem isn't with the EEPROM, FLASH, or noZKT mod.

So now I'm left with thinking its really just a defective receiver. It's been working for about 1 year without any mods, and about 3 weeks with a noZKT mod.

Any suggestions will be appreciated. I really don't want to have to spring for another receiver!!

[lefty]

Mine is missing the card door cover.

Is that available?

[DJmistral]

I think that my problem with the 430 is decoding the signal. Because when scrolling through the guide, there's sign of any signal delay. It really happens only when watching a channel. Anyone know anything about signal decoder problems with receivers?

djmistral if you pop the cover off the reciver and look towards the back where the cable
comes in there are two tin covers one small one bigger.the small one has a black round cap on it pop that off and you will see a pin that is ajustable make sure the reciever is all connected befor making any ajustments just turn it in and out and see if that helps .Iv done a few like that and it corected the problem good luck...........
