I set out to take my light sixer and get rid of a horrible RF signal. SO I looked up the easiest I could pull off on my budget and went with the latest from Ben at
http://benheck.com/b...i2600VidMod.htm Unfortunately his tutorial is missing where 5+ v came from and doesn't cover a six switch unit so I was able to fill in the gaps with "the atari 2600 video mods comparison project" site. So I constructed the circuit and checked the components over half a dozen times so I know the're right. I also checked for bridged contacts as well. I removed the resistors for TIA pin 2 5 7 and 8 and I also removed the one at the audio point.
I now have wires for:
5v +
gnd
pin 2
pin 5
pin 7
pin 8
audio
As of now I have no picture on either a CRT or LCD.
Audio sounds fine on the CRT but is horribly muffled on the LCD. On this should I remove/ cut any other items on the main board for the sound to come through clear? Any help please. And to think I went to school for this stuff years ago.
ps I've rewired the circuit a second time with fresh wire and replaced the original 2n4401 with a spare thinking I may have blown the first one. Still no luck.
