Question about Harman Kardon AVR 25 MKII

2 Answers

I turn it on, it clicks off within a few seconds.

When I turn on my receiver, within a few seconds it clicks off. I have removed the cover. The fuses are all good. I have lifted up the board that has the rear speakers, center speaker, antenna, etc... however, I do not see any obvious burning or broken soder links. It stays powered up long enough to change from say phono to tuner. I believe it became to hot. Some of the tabs that hold items to the board described above, that are plastic show signs of slight melting.

    I have a h/k avr 520 that is doing the same thing. When the sb button is pressed and turns green, the unit turns on and the display flashes wtih info and then turns off.

    we have a AVR 630 which we are about to throw away because no one can seem to fix it. it will only stay on for a couple minutes, then each time it stays on a shorter amount of time. the repair shop said it works for weeks on end for them. now we have a Monster power filter, which we were hoping would solve all problems - but it didn't - the same thing happened - it turned off.

It sounds like a problem with the power supply. You might be able to find a place that can fix it, but I don't know for sure. It also could be a broken solder joint in the power supply.

Can you be more specific as to "plastic tabs that show signs of slight melting"? Like where are they in relation to components / power supply / heatsinks / power transformer? A first shot... it may be output power fets/transistors (one is open or shorted) that is making one or more of the speaker outputs go to the PS rail. DC shutdown. Does this receiver indicate any "overtemp" or "protect" warnings? I really need a little more specifics.

How to program New key switch 2000 oldsmobile silhouette

Key switch ? key fob ? Transmitter Programming ?
If you lose a transmitter, program the old and new transmitter(s) into the remote control door lock receiver's memory. Up to 4 transmitters may be programmed.
Important: Once the remote control door lock receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information, requiring the programming of all transmitters.
Program only 1 vehicle remote control door lock receiver at a time. If more than 1 receiver is being programmed at the same time, it is possible that the same transmitter could be programmed to more than 1 remote control door lock receiver.
Perform the following steps in order to program the transmitter:
  1. Remove the ignition key from the ignition lock cylinder.
  2. Remove the BCM PRGRM fuse from the fuse panel. Refer to Fuse Block in Wiring Systems.
  3. Close all of the doors.
  4. Close the lift gate.
  5. Turn the ignition lock cylinder to ACC.
  6. Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.
  7. Open and close any vehicle door.
  8. A chime will be heard when the system enters the BCM programming/diagnostic mode.
    Important: After 7 seconds, a chime may be heard confirming successful synchronization. It is necessary to wait approximately 14 seconds for a second chime that will confirm successful programming.
  9. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
  10. Repeat the previous step on each additional transmitter to be programmed.
  11. Remove the ignition key from the ignition lock cylinder.
  12. Install the BCM PRGRM fuse back into the fuse panel. Refer to Fuse Block in Wiring Systems.

I have a dead MP780 also. I opened up the left side panel, and it looks like there is a fuse on the circuit board. I will test it tomorrow. The fuse cannot be replaced, however, without removing the soldered component from the board.

Good Day;

The fuses tell you that circuit has failed and was drawing too much current. No other test is needed.

Good Luck, big Irish.

Onkyo receiver with no sound

There should be 3 clicking sounds coming from the amp. You amp miss the last clicking sound coming from the speakers ,spk, output terminals. There should be 3 relays on the spk output board. Their 12 contact points may have a layer of black colour oxide. Remove the oxide can fix the problem, perhaps.
1. Unplug the amp.
2. Open the cover
3. At the spk terminal, there is a horizontal board.
4. Look for the 3 relays and take them out.
5. Open the relays and remove the oxide layer by a sandpaper.
6. You need an iron solder, a desoldering pump and solder.
7. If does not help, check for the 24V for the 5 relays. 2 is for B+ and B-.

Wont turn on

The solution is to replace the main power relay. I ordered a replacement relay from Vance Baldwin Electronics - part RELAY DC DG12D1-0/M11 RXV2095 (V6881300). After installing the relay this morning, my receiver now stays on continuously like it is supposed to. You can easily fix this yourself in about an hour. All you need is a screwdriver, a soldering iron, and some solder.

Home Error

A21 Home Error refers to the printhead not moving. Most cases, it is due to the fuse being blown on the main logic board. You have to remove the top cover. Open the clear cover, pop out the plastic pins, remove, then pull off the tractor knob on the right, remove the two screws at the top back of the printer, lift up the cover from the back towards the front. You will have to unplug an electrical connect ribbon from behind the control panel. Check the fuse and replace if necessary.
