bithead - do you have manuals already? I am helping a friend with his unit, an AP83. There are 4 green LEDs that come on, then go off. They do NOT change to red. The unit is dead otherwise. I can do component replacement if we can identify what needs to be done. I am not very skilled at troubleshooting whole power supply systems, though. If we absolutely must order a manual and it will tell us what to do, I will have him get it. Thanks for any assistance.

| The model is 50UX58B. I checked one fuse and it was fine. Are there more to check? If so where are they. The chassis is AP83. Thanks. |
