It's a Insigna 42" first had the neon/ negative display. Checked voltages at power supply, all within tolerance. Caps look good, I know, replace anyway. The T-conn likely suspect. As per Tom66, the vg reading were not sequential.
So, I wanted to try to replace the AS15-hg chip on the infamous AOU t conn. Well I desoldered the chip using a soldering iron and flux. and the middle metal square was still stuck to the pad. I guess the chip got to hot and perhaps it melted on it, or it's not that important as it maybe a ground.
Now, a replacement was put on anyway using paste and heat gun. Tried to watch the process very closely to prevent burning the chip. Pins lined up good and removed the bridging as well. First time doing this. Anyways, the screen is now white with ghost like images barely appearing. I have one chip left and was wondering if the pad should not have a metal square in the middle, and what is the best way to afix the final chip? Of course what other possibilities should I consider before buying a new t-conn? I don't own a hot air gun. btw.
I will post pics very soon and a more comprehensive description of the problem.
