KDL40W2000 9 Flashes

[simono]

Hi,

my KDL40W2000 attempts to switch on but displays 9 red led flashes - have looked it up and its:

DTT Trouble (Communications / BS_CS_PROT)

I replaced the tuner board (1-869-657-12) but this didn't cure the issue. The following post points to the board carrying the CI port (1-869-656-21):

Since I don't use the Freeview as we are on Cable I have tried disconnecting this board and I can now switch to the hdmi port but after about a minute it switches off and on and stays on again for a minute. This repeats three times then it goes back to the 9 flashes error.

Is there a way to permanently deactivate this board? Would rather not have to replace this board also in case it isn't that either.

Thanks in advance.
