Sony str-de-545 a/v receiver

Just answered that question for you in another post, but here it is again in case you miss it.

Hi there, Is the socket actually broken, or is it just playing up. It may just need some dry solder joints reflowed to fix it. If you are lucky, this may be done without a full strip down.

If you need to replace it, you will have to pull the board out of the unit, or at least the back panel completely off to get access to the soldering of the socket to replace it. This is not a difficult job, but often requires almost complete disassembly of the amp to do so. Time consuming...yes. It is something that unless you have some confidence at dismantling and reassembly gear, I would suggest that you refer it to a repair man. Good luck, I am happy to answer any more questions you may have.

regards
Graeme
