I have 7 Philips 19pfl3403d/27 Lcd's all with the same problem. They work fine until they sit over night. In the morning they will not turn on. Once I unplug them for a hour or so they work fine. Very annoying! I have one good unit and first swapped power supplies. That did not fix it. I then swap video boards that did fix it. Could this be bad caps? I have replaced swallen caps before but none of these "appear" bad, I am thinking of buying the service manual but I have limited electronics experience. BTW if you unplug them at night they work in the morning.
Thanks
