I did have some success resoldering some address lines in the ribbons on a 720p Samsung that the fools I used to work with broke off using very small copper wire.p a few months back that was a task I tell you.

Hi,
I know is a old thread.But i have got similar issue.
The problem with the TV began after turning off the main fuse in the house.The TV switched on, but the image started to flash and turned off after 1 minute.
After turning on the TV, the blue LED lights up, but then turns off and flashes red.
TV on the front panel Flashing 2 times on red and on the PSU 3 times.
I bought new PSU but nothing change(may by is broken as well).
Any tips on how to check the power supply?

They appear to be very close in specification.
The main difference that I can see is that the FKP330C has a Drain to Source breakdown voltage of 330V and the "A" only 300V Personally I would look for something with an identical or higher breakdown voltage.
You could contact Sanken and see what their substitute would be
