Toshiba 42HP95. They are well known for killing the Seine board I guess but they can be tested out by removing power from that board and that did not work. When power is applied, the PS will fire a relay on the board, bring up 2 fans, wait about 5 seconds, then kill the fans and throw the famous red blinking light.
I am still learning on power supply repairs. Not sure if this noise from the supply is normal or not. It is a buzz but only audible from about 2ft away if you are listening for it. I removed every load from the PS and it still makes the same noise. Coming from the inductors it seems. Bridge is good and never blew a fuse.
Also, I am NOT a TV repair guy. After testing the PS with no loads, I was going to reattach the plugs and when I tried reconnecting the Vsus plug, I got some arcing. I realize things were charged up and I did not connect it wrong but wondering if this is a poor practice and can damage anything? I am used to the old TVs where there was a service switch to drain the caps but these don't appear to have anything.
I am very much suspecting the power supply but honestly pretty overwhelmed. All caps "look" fine. Probably about 30 FETs on it so that will be fun.... Just not real sure what I might be looking for if that buzz is deemed an issue.
