    midway through playback the display read poweroff, and the unit turned off.

    I can turn power back on, but when the relay should "click" after 5 sec to power the amp circuit it displays poweroff and turns off

    What are the instructions i need to repair this my self?

  • jason May 11, 2010

    it will need repair , you will need to take it to an electronic repair shop , unless one of the speaker wires are touching the other terminal then the overload protection circuit is engaging because of that

    but if thats not the cause then it will need testing to fix the problem

This unit is going into protect mode because it detects a problem. The unit shuts down to prevent further damage internally. This usually is caused by shorted output transistors in the final stage of the amplifier. This is a simple fis for any shop that does audio repair. Expect a parts cost between $15 and $30 along with the local labor rate. If you wish to attempt this repair yourself, update this and I'll try to provide you with more details and instructions. You will need a multi-meter and soldering equipment.

My Samsung dvd/vhs player will not stay on. Says hello, then bye a couple seconds later


Sounds like a bad power switch. When you push the power button, it will initiate the unit to turn on, but if the switch does not keep the power on to the unit when you let go of the power switch, then the unit goes into shut down mode. Then the unit will display good bye. I would have the power switch looked at first.

Why will my rts he 10 not stay on no longer than a couple of seconds


Have you been playing the unit really loud or have you connected more speakers to the device, than originally came with the unit? I had a Yamaha unit and connected 4 extra speakers to the unit, which eventually overheated the device and the device would simply shut off, until it cooled down, however; the unit finally failed and burned up. I used a fan to keep the unit cool, until it finally failed, though......

Turn unit on,light stays on for 5 seconds and shuts off,robot doesnt move


If the power supply switch is popping off after a couple of seconds the most likely cause is a failing rectifier. You may want to ship it to a service center to confirm that is the issue and that the switch, which is also the circuit breaker, and the PCB inside are OK. For help finding a service center contact Matronics directly at www.maytronicsus.com or 1-888-DOLPHIN.

MY R.C.A. MODEL 20F420T WILL NOT STAY ON. TURN IT ON IT MAY STAY ON 3 SECONDS TURNS IT SELF OFF TRY AGAIN IT MAY STAY ON 2 SECONDS BACK OFF THANK YOU ????


The first couple of seconds of operation, most TVs are doing some self-test and if something has failed making full power on dangerous (for fire) they will shut down. Either a major component in the horizontal section has failed or the main power supply itself is defective.

Check that the fourth burner tube is set properly into the unit. Then turn all burners off, turn off the natural gas supply or remove the LP tank. turn all the burners on (don't try to light) wait a couple seconds turn all burners off. reconnect gas source. turn on gas, open burners fully and try to light.

My new Clarion CMD6 stereo won't stay powered up.


If all power and ground are good to go then the unit needs to be fixed. Being that it is more likely to "see" moisture, it may have water shorting out the circuits.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

Pioneer VSX-D409 - Remote Control Problem Hello. I'm from Brazil and I have a 12 years old Pioneer VSX-D409 Receiver. My problem is related to the page 16 and 17 of the Owner's Manual. I'm trying to do the steps to Set up the surround mode, changing some settings and the type of connection I use to delivers sound to receiver, using optical cables. Well... I just cannot enter this mode, the surround setting mode. At this moment I'm hearing the sound from a FM station on the speakers. But just this function works. Tuner, wiht FM station. The remote control works only to: - Turn on or off the receiver. - Change the volume level. - Set the loudness function (on or off). - Change the function of the receiver (to select Tuner, DVD, TV or other device in, but I don't gain access to change some specs like distance, speakers volume levels or type of connection of each device). And nothing more. The remote control has seven buttons on the top: DVD/LD, TV/SAT, VCR/DVR, CD, TUNER, CD-R/TAPE/MD and TV CONT. According to the source device you want to use, you just press the button and the receiver selects the IN connection (coaxial or optical or just the Tuner to listen FM stations) and reproduces the audio. Until last week, anytime I press this button, the source device was selected. But, of course, I didn't use all of them. Just two: TV SAT and DVD. Why? This receiver has two optical IN units on its backside. I have two optical cables connected in the receiver. Optical 1 is connected to a PS3 and Optical 2 is connected to a SmarTV. Before my hollyday's trip, all the connections were allright. But not today!! The problem is: I do not have access to the process to change the type of connection that is assigned to the device I've choosen. I want to do this: TV/SAT --> OPT1 (to the audio from PS3); DVD --> OPT2 (to the audio from Smartv); The process is described at the page 16 to 21 of the owner's manual. But, it doesn't starts. Seems my remote control just forgeted how to do this or is blocked in another function. I don't know how to fix it and need some tip or help. Thank You! :)
