Hey hobbyists, great forum!
Sorry for the crappy pictures, but it's better than nothing.
I got a Samsung 940N which had blown caps, but then once I got the backlight on i saw that the LCD panel was cracked as in image 1. So I thought "Hey, I have the 19" panel out of the BENQ/LG Philips i can try to shoehorn in there". So I managed to do that and get it all put together to create my SamQ/LGSung monster!
But there's a problem - there is a very annoying flicker in the image. It happens with DVI or VGA images, but not with the internal monitor images (ie. "Analog, Digital, or No Signal" boxes. It is only a vertical flicker.
I am guessing that it is EMI from the power board. Either because the LCD panel circuitry is bigger and a lot closer to the power board, or because the LCD panel connector is actually very close to the power board now. Originall on the 940N the LCD connector is about 1/2 way to the right side, but the LG/philips connector is in the middle. I know, the pictures don't help.
I am going to try wrapping the signal ribbon in foil to see if it will help, but I thought I'd throw this out there as a more interesting problem than the usual caps, drivers, and transformers.
