View Full Version : Intellivision II not powering up?
I picked up an INTV II yesterday at a flea market. My excitement to try it out quickly died when I attempted to power it up... I was met with absolutely no power light. Not even a flicker.
Everything looks fine cosmetically. There are no rips or damage to the power cable. The connector fits tightly in the system. It's an official Mattel power supply... I'm at a loss for what to try next. Believe it or not I've never had a problem like this with any system. Anyone got a suggestion of what to check?

Stick your tongue to the end of the plugged in AC adapter. If it feels like a 9V battery, it likely works. If not, you lkely found the issue.
Do not use an NES AC adapter with your Inty2. You will kill it.

Well, that was just a LITTLE bit stronger than a 9V.... It definitely works.

Doesn't it use a 16v AC adapter? Too lazy to look it up right now.

Correct.

The OEM supply is 16v AC, but you don't need it. I use a 12V DC supply on mine.
I was doing a little browsing and I found this at vidgame.net:
"The INTV II could NOT use the NES power cord. It required its' own because the Mattel Power cord was a bit thinner. #5872-9629
Input 120 V 60Hz 19W
Output 16.2V 955mA.
Another was:
Input 120V 60Hz 19W
Output 16.2V 1A"
I checked my power cable and I have some different information...
Input 120V 60 Hz 25W
Output 16.7V 1A
Model 5872-9629

That's the beauty of most AC electrical inputs. You can feed them DC and their rectifiers could care less.
And the even cool part, you don't need to care about the polarity at all.
I use my Genesis 1 PSU on my NES and it works great.
(But as said before, NEVER! ever hook up the NES supply to the Genesis)
Would the extra 6W of Input or .5V of output be a potential issue?
If not, should I just pull the system apart and scrub it down?

Extra wattage or amperage is never a bad thing, because the system will always take only what it needs.
The extra .5v? I don't have an Intellivision and can't tell you that, but I don't see a problem.

Works for me. Thanks for the info.
I opened the system up and it looks extremely clean. Not even a speck of dust. I'm stumped at this point.

Can you take a picture, with the best camera you have?

Sure. Give me a few minutes.
I jacked the picture size as high as I could so that you can see as much as possible. I think Photobucket shrunk the picture a little, but hopefully it'll work:

Yea, it does look very clean.
Hmm, hopefully someone else can find something I'm not seeing.
Nothing appears burnt at all.

Thanks very much for all of your help. I appreciate you taking the time to hang in there and help me out.

Perhaps the solder points are broken where the power jack is? We'd need to see the underside of the board.

It's probably best to follow the voltage checks in the service manual (available online). There's a nice flowchart there and everything.
