The Sony emblem and green power light on the bottom of the tv still light up but flicker off then back on probably once a minute or so. Otherwise the screen is solid black from startup.

This can be the panel itself, and or the matrix decoder/driver boards. The cost of this type of repair can approach the cost of a new set. From your description, I am thinking it is the panel itself that has failed.
Parts for your set are from Sony only because there is no third party manufacturing for these types of parts and assemblies.
Usually, when these types of sets become defective they are usually not worth servicing. During warranty the manufactures generally give a new set to the client, or they give a re-built set which has been built up using parts and modules from other sets that came back for service and had different types of problems.
If you know a tech is is good at servicing these types of set, maybe he can find a number of scrapper set of the same model to take parts from. You just have to hope the ones he finds have the same types of fault.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Sadly, a replacement screen itself would cost more than the TV is worth.
Here are a couple of web sites selling the replacement screen:

I know it seems like a crazy price. But, TV manufactures buy a mass quantity at a lower price. Where buying just one screen panel cost an arm and a leg. Buying a new TV is the best choice money wise.
