So,with all of the great advice I learned to solder, took my LG Plasma Touchscreen 60PZ850 apart. I removed the X & Y Sustain boards and checked solder. Sure enough, dry solder under the coils. I resolder and reassemble, turn my beloved window to my soul on and Wala! Beautiful restored colors, crisp light areas.....wait a tick...
The bottom half of my screen is now dead. Not discolored or dim, but completely dark. As if someone placed a pitch black board over the bottom half of my tv.
I checked the connections between the boards, re-re-assembled, and checked the soldering again. I did notice that on 3 of the connections between the boards there is no solder but a component pin, pics attached, I'm not sure if there was never solder or I somehow knocked it off, but the breadboard holes look way too clean. Or if I somehow ripped the flat connection cable connected to the bottom of the board, pic attached and there seems to be very mild damage. Or did I somehow break the white connectors between the boards? I checked pretty thoroughly of secure connections.
So, Help? Please! I may try to beg a new flat connection cable (the white ribbon cable) to see if that's the cure. But could I be missing something? Should I solder those weird loose pins? Or would there be a reason to leave them loose?
