My Sony player won't eject either a or b

SOURCE: NOTHING WORKS ON DVD PLAYER

My daughters had the same problem, try replacing C411 (I think that was the number on the board), its a 10V 1000uf capacitor in what appears to be the 5V power supply section toward the right rear of the main board, that fixed it. On hers the capacitor was swelled up on the end. I checked it out of the circuit and the DVM I used only indicated it had about 500uf capacity.

Try this. This works on some brands and models.

Power up the unit. Using the remote, press and hold the 'STOP' button for about 5 seconds. Release and press the 'OK' button.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Someone is going to have to open it and look to see if the disc inside is out of position or jammed in some way----sometimes you can gently move it a little back into the position where it will eject the disc--which could be your entire issue.
