Hi All,
I have been given a Sony Home Cinema system that isnt working. I have ran through a number of trouble shooting/ testing exercises and have found a lot of the main components to be OK ( well the usual suspects anyway)
What I came across where these 4 heat spreading diodes...all of them are showing the same resistance values in both directions...so I took them out in the hope to replace them.
My issue is, is that I cannot find what rating they are, and also the part numbers I have from the Sony sheets I have are for Sony specified sales only.
I hear Sony have been known to only use specific components in their stuff? I have even emailed Fairchild to ask them if they know anything about it as these items appear to be Fairchild components. They haven't responded.
Can anyone help me find these bits, I would be very grateful indeed!
