Toshiba 42HL196 LCD: Three blinking light problem

[itshockedme]

I'm looking for some assistance troubleshooting the power supply board. I've done research and already replaced the most common components suggested by others for the TV not turning on with three blinking lights. After replacing Q820, Q860 and Q880, the TV was making a clicking noise and would not power on. Then, after replacing C888-C890 and D884A, the clicking noise returned when pushing the power button. So I'm back to three lights blinking and no powering up. I have the factory repair manual for reference and can give meter readings if someone can assist me in testing some components and/or any other suggestions. Thanks.

Can you post the service manual? Does it have the diagram of the power supply board?
