How do i fix my lg flat screen (flickers on/off) have replaced LED and board?????
If the LED backlight strips were new and you have all the connectors seated correctly it has to be a power board issue, or more specifically an issue with the inverter section of the board, remember its the B- section that is regulated not the B+, start by testing B+ to frame ground and see if you see 100+ volts on both circuits, next test the ripple, I've seen the inverter caps fail on this model a few times, other option would be replace the main board but I'd pull the panel out again and make sure all connectors are good, you can power the set up with the panel out but unhook the panel at the tcon not the panel to be sure the connectors don't short to the frame when it's powered up.
Problems with LG Studioworks 700B CRT monitor.
This positively is a capacitor issue, when the caps are cold, they lose capacitance, if you put a blow dryer at the vents and warm the set up I'm guessing it will power on first time. I'd replace all the caps in the power supply section not just the ones that look or test bad

TV LG 42LB5800 T-con board failed?
It's possible you damaged the tcon. When you connected the ribbon connectors going from the tcon to panel boards you may have damaged the tracers, remove the connectors and see if those are bent or broke off. Another possibility is the panel was damaged when it was handled, you need to use static protection when handling the panel, if this wasn't done it could be damaged
