I did look but I didn't see anything. I'll crack it open again tonight and take another look but so far its got 2 brand new PCBs in it, only the small PCB that the power/brightness adjust buttons are connected to and the LG PCBs are left. I suspect its one of the LG PCBs; I can upload pictures of all the PCBs if you think you could spot a messed up capacitor
UPDATE: Decided to just crack it open now, definitely no signs of bulging anywhere. The new PCBs look fine, and I check all 3 LG PCBs under the metal panel. I even popped off the LCD brightness/Power buttons and check that board, which was fine. I snapped some pictures but the lighting isn't great and the camera didn't capture them very well. I'm 99% sure there is no visible signs of capacitor swelling. I do notice an audible buzzing coming from just that monitor when it is displaying something though, not when the screen is blanked out however.
UPDATE2: I decided randomly to time how long it takes the monitor to come alive - it takes exactly 9 minutes. I timed it 5 times and every time was exactly the same, 9 minutes on the dot. How bizarre anyone have any ideas what is going on?Edited by tehpsyc - 3/24/13 at 8:14pm
