If the screen flickers when the lid is moved, then it is most likely the LCD ribbon cable has a bad connection to the LCD controller board. If it flickers without lid movement, then it is probably the inverter module for the LCD, but if it flickers constantly and especially if there are white lines that stay constant accross the display, then it may be an overheating or failing GPU. Check the air vents on the unit and make sure that there is no blockage if the latter is the case.
I have the same problem. It started about a week ago and I have to keep flicking the on switch to get it finally working. I think there's a problem with the contact with the base. Not sure if it's worth getting a replacement part for it. It worked well for 4+ yrs!
Did you replaced 2 IC convergence as well or just 2 resitors 3.9 ohms ? if you did replaced 2 IC then you might have probelm in convergence drive it is1 of the PCB mount vertical on the left side from the rear view under part BP95-00415C you need to readjust the convergence by using your remote control just follow in the servive manual
