The machine constantly switches off, goes to standby or simply freezes mid use. It got so bad that eventually it just wouldn't power up. It's been back to Lexicon twice - recently they replaced the the power supply and said it was 'fixed' This is the first day of using it and it's no different.

    Hey Dan
    Thanks so much for the reply. In answer to your questions
    1. It fails when on for fifteen minutes. Then if the unit is switched off
    it will turn itself back on and go into 'standby' mode and then flash the lexicon logo and then freeze.
    2. Yep, see above. The only way to turn the machine off or to restart is to switch off the main power at the back of the unit. Then as explained above, it will only run for about 15 before freezing.


    The only thing done by the service centre was the first time they sent it back saying nothing was wrong. Second time they updated the software. Third time they replaced the power supply.


    Thanks again.

    Sorry Dan, tried to respond before but I think it got swallowed in cyberspace.
    In answer to your question
    1. It's after about 15 minutes of use it freezes. The only way to turn it off it to switch off power at back of unit.
    If the unit hasn't frozen and I switch it off manually at the front of the unit or with the remote, it will wait 10 minutes then turn itself back on - and then promptly freeze.

    2. See above ;)

    The unit was sent back 3 times.
    1st time they said there was nothing wrong with it
    2nd time they updated the software
    3rd time they replaced the power supply and told me it was a favour as
    it was 'out of warranty'. The machine has done this since 2005.

    At the moment I have the most expensive amplifier I've ever heard of that has since day one been a lemon.

    Any help appreciated.

I have access to the Lexicon service guys, but will need a bit more info to assist in tracking this down.

1) Have you noticed any pattern to when the unit fails. In other words, does it tend to fail more readily after being on for a while, or is it consistant in behavior regardless of time?

2) Does the volume level of the unit change the total time before failure?

3) If you uinplug the unit for 1/2 and try using it, does the behavior change?

Please update this with the answers and also, if you could post what has already been done by the service center, that would help as well.
At this point, I would be suspicious of hte 5V line and/or the microprocessor internal controls. I'll research this a bit and try to get you more details as well.

Thanks,
Dan

    One more piece of info please. Where did you send the unit? I have access to the Lexicon service folks and would like to look this one up. Send along the service ticket number as well from the last service. I'll research this and post any new info I can find.



    Thanks,

    Dan

Elonex tv keeps going onto standby, take about 10-15 goes to work.
Sounds like you may have some capacitors going bad. If it is a high end TV it may pay you to take it to a repair shop.

My Pfaff model 1211 machine won't come on. The power switch has been replaced but no light and no power for stitching
Sounds like a bad connection somewhere as the power seems intermittent. Consult your repair man to check the electrics.

Define hibernation & stand by
Hibernation: The computer saves all data currently in memory and all open programs just as they are. It freezes everything in a way. All the saved programs and data are written to the hard drive for storage. That way the computer can sit for a long time without drawing power to keep the open programs and data saved. However, it will take a longer time to wake up the computer.

Standby: The computer does not save open programs and data to the hard drive. Instead it keeps everything open and simply goes into a super lower power state. The memory receives a constant stream of minor power so that it can keep the programs and data in memory until the computer is woken back up. The computer will wake up much quicker but will draw power slowly as it sits in Standby mode.

My playstation 3 beeps twice and then freezes mid game not even allowing me to turn off the system without using the back switch
Sounds like a firmware issue. Happened to me after I had an update. I was told by Sony to wait for another update. Turned out it fixed the problem. Also check on your memory, if you're running low..delete some etc...might resolve. Lastly hold down the front power button for 5 seconds until you hear 2 beeps release it and this should reset. Here's a link http://www.youtube.com/watch?v=dMexfcOzreE&feature=youtube_gdata_player

My plasma's power light is orange and when I press the on/off button nothing happens. What should I try next?
Hello Sir, hi, when your TV's power light is orange, it's on "standby mode" meaning the power supply will not respond to any power switch press. the standby by mode can be anything, this could be that the TV is not receiving any signal, this could also be that some thing a part or a section of the TV goes bad that makes overload. This needs to be checked thoroughly, I cannot be particular on this section simply the trouble is to broad to explain, this needs a pro for checking, but if you want a quick answer, simply replacing the entire power supply board will restore the TV back.

Dishwasher pumps even with power off
Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.

Avr 235 power at standby mode but sometime unable to power up, please help. A lot of thanks.
Open the unit and measure the voltage across the reset microswitch on the transformer board (with the unit in standby). It should be a hi signal, over 3 volts. If it is low, below 1 volt (when you can't turn it on) it is sending a constant reset signal to the cpu. Remove the switch and try again. If the problem goes away, the switch was bad. Its a service switch so you don't have to replace it.

Tv stays on standby when switched on, then switches itself off after a minute or 2. Then may show a picture after several attempts to turn on, but will turn off again after a few minutes. It does...
I would suspect this has issues with the power supply, I would put it down to faulty capacitors, take the back off and look on the power supply for domed shaped capacitors, they may also leak a brown liquid like substance.
Replace these and all should be ok if it is capacitor related.

No powerr
If the led comes on for an instant and then faints quickly, leaving the TV with no led, no blink code, and no power at all, then the fault is usually concerning the PSU board, or the power connection. If you already replaced the cable, the next step is looking for bad solder joints on power cord connector, and then testing and eventually replacing PSU board.
