Bad soldering on the LM4766T amplifier IC's. A lot of work to disassemble, but worth it. Good Luck

Posted on Aug 16, 2010

Mine did this last year, turns out there was some problem with the soldering on the circuit board. Take it to be looked at, easy to be re-soldered and cost me about £50.

My onkyo HT RC330 will not power up at all. Have had problems past couple of months with starting it but if you played around with swith it would start. Now nothing.


Try resetting the AV receiver To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press 8 ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter Standby mode.

It is possible that the protection circuitry has been activated. Remove the power cord from the wall.. Disconnect all speaker cables and input sources, and then leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect only the power cord and set the volume to maximum. If the AV receiver stays on, set then the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your dealer.

If the standby light is lit it and the unit will not boot it is most likely that the protection circuit has been activated. If there is no standby light then check the fuses. These units check that the power supplies are operating near specification. If a capacitor or resistor in the circuit, or a broken solder connection the unit will shut down. Because of the temperature the thermal cycling around the power supplies a broken solder joint can occur. This will make for an intermittent operation.

Hope this helps.

How do I turn on my rca tablet I tried everything I put on the charger , I keep my hand on the power botton it still wont turn on please help me


You need to do a factory reset, follow these instructions:

Step 1. With your tablet turned off, press and hold the volume up (+) button. While holding the volume up (+) button, press the tablet's power button until you see the RCA logo with Nipper and Chipper on the screen. After a few seconds, the screen will change and you will see the Android bot on his back with a caution symbol above him.

Step 2. Now you are going to press and hold the tablet's power button, and without releasing the power button press down on the volume up (+) button. You should then see the screen below.

Step 3. Use the tablet's volume up (+) and down (+) keys to navigate to and select the "wipe data/factory reset" option. To select this option, press the power button.

Step 4. The tablet is going to ask you to confirm your selection. Use the tablet's volume up (+) and down (-) keys to navigate to and select "Yes - delete all user data." Once again, use the power button to select this option.

Step 5. At the bottom of the next screen, you will see "Data wipe complete." Press the power button to restart the system.

DVD is stuck in Bose lifestlye 48 media player


We had a power surge during a thunderstorm that dimmed our lights, and after that the CD opened as normal.

A friend suggested that I pull the power connector, press the open/close button and hold it down as I reconnected the power connector. The power surge beat me to that, so I don't know if it works. It was more than "Tech Support" could offer however.

Lx 9000r wont play any dvds even previously played


You can try reseting the unit.
Reset the set to the default factory settings:
All the information stored
(programmes, time and date) will be lost.
1.
Disconnect the set from power supply.
2. Press and hold down "STANDBY•ON" on the set and reconnect the set.
3. As soon as "IS TV ON?" is displayed, release "STANDBY•ON."

Hopefully reseting it will clear whatever problem it is having and allow you to once again use your DVD player.
Hope this helps. Good Luck.

Protection displayed and shuts off


are all the speakers good?? discont all the speakers and see if all the lites come on. Then shut off and start to connect one at a time untill the unit shuts down and then you know you have a shorted speaker. If the same thing happens you probably have a power supply or an output stage falure and this should be serviced by someone who is quilified to work on stereos
