Resister repair before A/V mod ( IntelliVision )

Double posting is frowned upon here. You're writing sentences - use a new paragraph, not a new post. It clutters the thread.

We weren't talking about the wattage at all. We were talking about testing the resistor - to see if it's good or not. And it's resistance, not impedance. If you want to find out what the power rating is, increase the power until it burns. That's your power rating - and you've killed your resistor.

It's a shame you don't want to read further into the subject because a) it's useful and b) that book would have given you the answer to the very question you asked:

I've tried telling him that. I don't think he's listening. Without having the service manual in front of me, I'd imagine this resistor is in the power stage of the circuit. If it blew, the machine probably wouldn't work at all. It has sod all to do with raster, anyway.

...and that's how you reply to two posts with one!

 

I love these threads.

 

Update. I have another working IntelliVision and it does the exact same thing. So it's not the IntelliVision, it is how the RF signal is handled on my TV. That being said, I finished the MOD and it works now. This one is running fine with no flickering.

Here is the advice I've got since I've shown the picture to help me : "You're using the wrong size", "maybe not the wrong size", "size matters", "no it doesn't", "it's broken", "no it's not", "don't replace it", "replace it", "use double the rating"

What's next? "that isn't even a resistor Aaron..."

Anyway, Thanks for the shout outs!!!

p.s. The replaced resistor is the correct size + rating

 

Well, I did tell you that it was going to be your television, not the console. It's a common thing with old RF consoles. The whole testing the resistor thing was for your own satisfaction as you wouldn't believe us, but pretty pointless. The resistor is in the power stage, nothing to do with raster.

Again, I did mention that the composite mod would fix the problem - the problem is how modern televisions deal with RF, not composite. There are some televisions with composite and even RGB quirks - a CRT is still a better choice for some consoles - but that's a separate issue

Glad you got it going, anyway! Now consider that bedtime reading - might come in handy when you get another faulty console.... or your LCD television PSU dies in a couple of years

 

Thanks so much for the help. I thought it might have been the IntelliVision because the TG16 and the NES work perfectly through the RF. Yeah, I actually have another IntelliVision that I'm going to do the mod to also. The guy at the electronics store sold me wire that was hard to use to save me money. That I won't do again.

Again, thanks for all the help!

 

You would be surprised but some devices (quite a few TVs and Capture cards) don't like the NTSC video the PC-Engine (what you're calling TG16) puts out. So it's something interesting to keep in mind.

 

yeah for sure. I'll give you guys my entire setup just so you know why I did what I did. I bought the IntelliVision for my wife, because that was her favourite childhood system. When I tried it at the store (CRT - stupid me) it worked perfectly every time for every game. Bring it home, open it two months later for xmas and the screen is amazingly clear, but jumping up and down. Now here is the kicker. There was one day where we were able to play for about 30 minutes where it didn't jump around at all.

Then we played the next day and it did it again. I opened it up and saw the resister that was damaged and decided to come here and ask. Even though the resistor was in the power portion, I was still going to change it no matter if it was a moot point or not. Also, it isn't just glue that fell on it, if you look closely, the shell has actually peeled away and there is a small incision in the actual resistor. I work at a place where I was able to get the engineers to look while you guys helped me out. They/we build robots that dispense drugs... it's pretty slick. I just test/software.

So, now I have an intellivision, NES, TG16 and Atari Flashback that all use Composite outputs. However, my TV only has 1 AV input. I then bought an AV selector (Dynex) that can support 4 AV inputs. That covers my 4 retro consoles. Here is another kicker... the TV (new, but cheap) has the Component and Composite inputs sharing the same Audio. That means my N64 which has the component cables can't use this component input, unless I keep on toggling the audio cables depending on which I'm using (the 4AV games, or the 1 component game)

That situation helped me find a AV2HDMI device that should be here today or tomorrow. So, those 4 AV games go into the AV selector which goes into the AV2HDMI connector. Now all of those 4 will finally go through HDMI into the TV. Hopefully this works. If so, that frees up AV and Component. We'll see soon!

The other 2 HDMI ports are for 360 and the Pi. Once this is all done and hooked up, I'll post the pics.

You made Bender?

It is a common issue, and there have been lots of reports similar to yours of jumping pictures. Glad the composite mod got it sorted for you! Always handy to note for future reference, too.

 

Yup!

Now I have another great question maybe...

Which external commercial RF Demodulator would you guys recommend? I have 2 IntelliVisions and I would like to use one on this TV without the mod. I have 2 Dynex LCD TV's which both take the IntelliVision through RF with no problems. So many choices???
