SONY system MHC-G88 is having NO POWER since yesterday. AC Input to Transformer is OK. This appeared suddenly as I pulled the board since I was trying to fit a Bluetooth Device.
Hi @sunilekhu , Was the AC power disconnected from the system before you pulled out the board? You said that the “AC Input to Transformer is OK”. Did you check the outputs from the transformer board are OK, you didn’t say? Check that there is power on the 2 AC power leads going from the transformer board to the power board
