I have an LG 60" plasma that is about 7-8 years old. A year or so ago it started getting some discoloration on the top part of the screen, but the picture still showed up and looked good on the rest of the screen and it always turned on/off just fine. Due to the discoloration I stopped using the TV, and it just sat in another room for about a year. I decided to try fixing it this past weekend so I did some reading online and learned that there are typically some solder joints on the YSUS and ZSUS boards that can crack and need to be reflowed. So I took the back off the TV (forgot to test it again before doing that, unfortunately) and pulled out the boards, and sure enough there were some cracked joints on the back. So I reflowed all the joints, but now the TV won't turn back on. When I try to turn it on I get a high pitched buzzing/ringing sound coming from the ZSUS board and then it shuts back off. When I turn it out without the ZSUS board plugged in then it stays on, but of course there is no picture.
Is it possible that i damaged something while reflowing those solder points, like if I used the solder iron at too high of a temp or something? Here's a video showing what's happening when I turn it on.
