I work in an electronic repair class room and I’m trouble shooting a Samsung LCD TV model LN40A530P1F and I believe it is the power supply. I am familiar with underrated 10 volt 100uf caps on some models. I’ve changed the suspected caps, this TV does not have that problem. Can you tell me which component on the power supply board is typically the problem when the power light flashes without video and the start-up sound comes on for a brief moment and continues to repeat this sequence?
