  1. Hi Stan, welcome to the forums. These are all good signs of the device not yet being fully dead. That the power button works shows your MCU is alive - it is sensing some of the buttons and can control the standby/power on led, therefore, it seems it is not blocked by a fault somewhere, that would cause the MCU forcing the device stay in Standby. That the disc load/eject works shows that your BD board is alive (might have some faults though - to be figured out later on). Let's begin with the trivial stuff: - I would first check the two ribbons that connect the drive to the main board. On the 500/510 decks it is fairly easy to seat one of the ribbons the wrong way, at the main board end. The wider one is pretty straigthforward (i.e., short enough, and folded sharply), but the other one can be plugged 180 degrees twisted around (I faced this issue a couple of times, and luckily those decks always survived this mistake). Both ribbons' contacts should face the rear of the deck, not the front. In other words, the ribbon side with the writing on it is facing the rear, the plain white side is facing the front. - second I would check the front panel's ribbon, for contacts peeling off like this, or being damaged otherwise: - then there is a display/controls check mode you can try, to see whether or not your display driver is alive, and/or the MCU can sense all other buttons/switches, as well as the IR sensor. Turn the deck off with the switch on the back panel, press and keep the AMS knob and the record button pushed, then switch the deck back on. The display should lit all segments, then by pressing each buttons one by one, you can turn off the segments one by one. Once all done, other tests can be performed, following the instructions appearing on the display. Let us know the outcomes of these checks, and we can take it from there.
