My RXV663 does not power up Ive had it for 2 yrs, I kept in storage inoperative for 3 months (unplugged and completely disconnected), when I connected it up, it would not power up, no clicking sounds, no display, nothing. I gave it to my dealer here in sri -lanka but i thing im being ripped off. They've had the amp 3 months now but still cant find the problem. they said they swapped the crystal 20mhz, the cpu, no luck now they are planning to swap the whole P.C.B Digital and see if this works - im getting the impression im being ripped off the pcb digital alone costs more than the amp. Could it be that protection ciruitry opereated 3x consecutively and disabled the power? if yes how can that be fixed any ideas on part nos? I simply cannot trust the dealer here in sri lanka please advise

Important: If all 3 passenger door locks are inoperative from both door lock switches, test the unlock control circuit between the splice and the BCM for an open.? Do you know how to do this ? Looking at a wiring diagram an using a DMM - digital multi-meter ?
Free wiring diagrams here http://www.bbbind.com/free-tsb , enter vehicle info. year , make , model an engine size . under system click on body & accessories , then under subsystem click on power locks . Click search button then the blue link . Or maybe your best bet mite be to take it to a qualified repair shop. You would need factory service repair info. to find splice location .

If the beep stopped then what is the problem you want help with now?

Hi,
Turn it off completely, disconnect power cable.... Reconnect printer power cable directly to the power board after that turn in ON ...

Thanks

sealing between heating element and boiler-body leaks the water - and it has probably shortcut the electricity by now: disconnect the powerplug immediately - and exchange the sealing

Try opening the case and unplugging all circuit card/mem modules/cpu and re-seating them in their sockets...may be during storage that heating /cooling cycles caused connections to go bad

1. completely unplug power cord from wall socket,
2. unplug power cord from printer
3. unplug printer cable completely from computer
4. unplug printer cable completely from printer.
5. let printer stay disconnected for approx 1 minute
Now securely:
1. reconnect the printer cable to the printer.
2. reconnect the printer cable to the computer
3. reconnect the power cord to the printer
4. reconnect the power cord to the wall socket

turn printer on

You may find that a connection has simply worked itself loose over time.

This issue occurs if your Ice Maker is not clean or have dust particals inside, follow the below steps in order to clean it properly:

Step 1 Lift the power bar located above the ice maker storage tray.

Step 2 Unplug the refrigerator.

Step 3 Allow the refrigerator and freezer to defrost. This will melt any large blocks of ice that have accumulated in the ice maker.
Clean the Ice Machine

Step 1 Remove the ice machine storage tray.

Step 2 Dump any water in the ice machine storage tray.

Step 3 Wash the ice machine storage tray using warm, soapy water. Rinse and allow to dry completely.

Step 4 Sanitize the lines of the ice maker. Consult your manufacturer's directions for steps to do this, because it's not available on all models.
Reassemble the Ice Maker

Step 1 Replace the ice machine storage tray.

Step 2 Plug the refrigerator into the outlet to restore power.

Step 3 Lower the internal power bar located just above the ice machine storage tray. This allows the ice machine to make new ice.

it sounds like the dmd board is failiing

you need to take the phone back and have it replaced for a new one.

Unplug the oven from the outlet, and wait 24 hours or overnight, and plug it back in. It should unlock and work ok.
