there are 2 types of flicker, one is the lamps that drive the display and the second is the sync signal of the video.
I assume the video sync is the flicker you see,
I would try connecting a different way to make sure it is not the tv,
connect using the aux /rca connectors to cable box.
and or connect using the cable direct bypassing the cable box.
I have seen several complaints about the hdmi cable signal being incorrect in some way,
this is the same issue that the svideo connector had in its early adoption signal was too hot or too low.
another thing to watch out for is the low light sensor on the front of tv if it gets an incorrect reading it can flicker the back light though it should be slow in doing so.
some times the flicker you see is not flicker but ac running through the sides of the picture from an ungrounded cable source.
how does it perform if you play a dvd player , with and without the cable box connected.

you didn't mention what software version your ps3 is. in this digital age it's important to keep software levels up to date, with some exceptions. i'm including the web address for sony so you can update the ps3, but i don't think it's the problem. once you're are on their site you click on the ps3 picture & that link will take you to the software update pg. there you can review previous software updates. i quickly reviewed 1 of those & didn't see anything that addresses your problem.
have you verified that the HDMI inputs are are enabled correctly? thereare 4 inputs. refer to pgs 25 & 26 of the owner's manual.
I would put the heat on your LG retailer. clearly the new main board is suspect. you had the functions prior to the swap. the board is probably defective, but with a different problem than what you had previously. i visited LG's site. they currently have nothing in their knowledge base that mentions the your problem, nor is there a software update.
if you need additional help. write back. good luck.

Connect the Wii and the DVD player to different ports on the TV to and any other device to the port in which the Wii and the DVD player were connected to check if the issue is with the port.
If other devices also display in black and white after connecting them to the port to which the Wii and the DVD player were originally connected then the ports require servicing.

You will need an HDMI to DVI cable which are available in the shops, even ASDA has one but I don't know how good it is. Or you can buy an adapter that will plug into one of the ends of the HDMI cable and then plug into the DVI socket at the back of the TV. The DVI input is video only so you will need audio leads for sound. These will connect from the output of your source, say, blue ray or sky HD (Left and right audio sockets ) to the audio L/R at the back left of the TV (on the block next to the three component video connections and s-video connections)
