Hi there,

Try swapping around the Scart sockets to a different input on the TV.
If the "No Sync" problem occurs with all inputs, then the board which controls the input signals is likely going bad and will need to be replaced.

Ok Alan,
Then the 'B' board which controls the input signals will need to be replaced.
These can be obtained from Sony, or through a TV repairer.
Alternatively, they are occasionally available on eBay.

Hello Pete,


 


What is the part number for the "B" board?


How much does it cost?


How easy to replace in the TV?


 


Regards

Hi Alan,
These boards can cost around £200 - you will need to check the part number printed on your own B board as they can vary.
It is a straightforward swap to replace the board if you are technically minded.

Hello Pete,


 


Is it easy to identify the "B" board when the back of the TV is removed?

Hi Alan,
The B board is a long board with microchips on it, similar to the following board:
