I'm working on my 4" mobo and it appears different (resistor wise) to the other boards... I have a type A board but the resistors and diodes dont match up in the pictures on the bottom corner. how should I determine which ones to move.

Also, i am noob with atari (I've done genesis and 360 work thats about it) and was wondering if someone could just identify which chip is which for me on the board when holding it upright (there are 3 chips from top to bottom beneath the cart slot)

thanks for helping

Traced the pins and followed the copmosite mod

but I used 200 ohms as opposed to 193 for pin 7.

I get no video signal at all, i tried changing screens and nothing. I connected the audio in pins on the psone screen (9 and 10 on the right) to the audio resistor spot in the tutorial but got no audio, just a high pitched frequency. I used a multimeter all around the board and everything is getting voltage, but I am not getting a picture or sound? NOTE: I did bypass the 450 ohms to the +5v source but that should have no effect except for brightness?

Any and all tips are appreciated

seriously i posted this forever ago, i could use some help.... the composite out on the system is barely 1v, which doesnt seem amplified enough to input into a psone screen... (this is with the book composite mod) . I worked backwards (instead of the version 2 mod) i used the circuit with the 22 ohm resistor and 2 1k ohm pots and the ctp.. please advise, if not I just have to get another 2600 i guess.
