Video Issue

I'm more worried about hurting myself!

 

Hmmm...how do you respond to that?  If you are worried about being shocked there is nothing to worry about.  It's a 9-volt power supply from the wall but the system only uses 5 volts of that.  You could run this thing off of 6 "AA" batteries for a while if you needed to.  Handle the board too tightly, though, and you can get poked but nothing there to shock you.  Besides...you can remove all electricity in the system by unplugging all connections to the console, including power, and turn it on for a minute.  After that there will be no electricity stored inside the console.  They are really a low-power device.  Lots of parts but it only requires enough power to operate an LED light...5 volts.  That's it.  I'll help walk you through it should you get the courage to try.

I'm going to say a bad capacitor in the video circuit.  If that before picture is what it was like when you first turned it on and the last picture is from, say, minutes later then that appears to be a capacitor that is no longer able to hold enough electric charge to perform its function.  In this case to hold enough to produce a quality signal.  Whatever you do I would not recommend throwing it away...please.  

 

Now a few questions:

 

  1. Was the image before and after sudden or did it slowly transition?
  2. How long was the console on before the bottom image happened?
  3. Did moving the console, or any of its wires, change the images back and forth?
  4. Are you using direct-connect or the old-fashioned RF switchbox that came with 2600s?

 

Give me a bit of time and I might be able to help you come up with a fix if you are willing to do some solder work.  Or if you don't want to do that yourself you might find someone close to you to help.  I would if I could but that would require shipping it.  These machines are fairly old.  The 2600 is at the very least, figuring the wood-grain design (including Darth) stopped during the crash, 33 years old.  Wires start to lose their integrity and can become brittle and lose the ability to sustain power and RF signals.  That is part of a worst case scenario.  

 

The thing that I have ran into the most with a few 2600's Mom and I would find in the wild at yard sales and such was with the RCA connector inside the console.  Unlike the 5200 that is soldered into place on the mainboard (along with a RCA connector???) the 2600 has just the RCA connector.  This allowed for easy connection of the RF cable...no soldering required.  This connector, however, overtime and depending on how well the console was handled, treated, and so forth, can be jarred loose.  All that would need to be done is to check the solder joints on it and solder them back.  That is the part of the not so bad case scenario.  

 

The machine itself is playing games so that aspect of it is working.  That's a plus.  So...it looks like somewhere in the RF circuitry there is a bad connection or a faulty part causing the effect of a bad connection.  If you are brave that is where I would look.  

 

You might have to try this step-by-step information to completely tear down a 4-switch model:

With the top off I would suggest connecting the power and RF back up so that you can turn on and check the RF connector.  That is the most effective way I have found to check that connector.  With the system on (with a game cartridge in the system of course) you can use your hand and gentle try to wiggle the RF cord where it connects to the RF connector on the board.  Don't try to force it.  You only want to see if trying to move it causes your signal to change.  

 

But it does look like somewhere in your system the RF signal is being disrupted where your TV is not getting either a ground or the signal itself...it's only getting half of the signal.  So I would suspect and check your cable and its connection inside the console first.  That is my theory and suggestions.  I would do it for you if I could.

I didn't get chance to test it yesterday, but I'll answer what I know now.

 

 

  1. Was the image before and after sudden or did it slowly transition? - Instantaneous
  2. How long was the console on before the bottom image happened? - Not sure exactly, but it's minutes, not hours. 10-15 perhaps
  3. Did moving the console, or any of its wires, change the images back and forth? - This I'm not sure of. Off the top of my head, I believe it does move the lines a bit.
  4. Are you using direct-connect or the old-fashioned RF switchbox that came with 2600s? - Direct-connect via coaxial

 

Also, I'm not opposed to shipping it to you & paying for it to come back.  ;)

 

It won't get thrown away either.  :D
