If the power supply fan is working when you turn on the pc ,it probably is not the power supply,
and is most likely a motherboard problem ,if you have the ability to install another video card that you have (or a friend may have), this may solve your problem.

i am not sure what you mean when you say "my system unit automatically turn on after i turn on my AVR "
good luck

Front display is totally dark. AVR keeps operating.


Do a soft reset. Turn off the system using the main switch on the back of the unit, then unplug it for 3 minutes. This should fix it.
Also consider investing in a power stabilizer as the avr is quite sensitive to power fluctuation.

I am currently on my laptop because when I turn on my desktop, the monitor (ViewSonic VX2235wm) powers on with a message that says No Signal Digital and then turns off. Any suggestions?


hi; your monitor has no problem, its your cpu. Try to hook your monitor to your laptop,and change the display setting to your LCD monitor. If LCD has displaying no signal mean signal coming form the Video card of your CPU try to visualize if you hearing some beeps into from CPU, some motherboard has beep codes if there's an error or failure to your CPU, 1 beep means its good system test. if you don't hear any beeps, try to check first your Video Card marmeto12_21.jpg if you have Spare try to replace it, try to reset all the connectors even Memory card to its slot. reset means pull the connectors and place it back again, also check the power supply of cpu if still functioning good.but you can test it by multi volt meter. if nothing happens check your motherboard most common failure is bloating capacitor, and overheating chipset. thanks....................hope this helps...................

Hello

If this is the first time to turn you on your computer check first the power supply of your computer if connected to their proper connector. Check your memory if clip properly in there memory slot. If you are using Video Card check it if it is properly connected to the connector. Then connect your VGA connector at the back of your computer when you have video card connect the VGA Cable of you monitor to the video card VGA output if does not have connect it with the onboard VGA output. Then press the power switch if the unit is still no visual in monitor try to search or hear a beeping sound in your computer by its on board buzzer. Find which beep you hear from your computer.

No Beep- No Power, Loose Card, or Short.
One Short Beep- Normal Post,, Computer is OK.
2 Short Beep- POST error, review screen for error code
Continues Beep- No power, Loose Card, or Short
Repeating Short Beep- No Power Loose Card or Short
One Long And Short Beep- Motherboard Issue
One Long and Two Short Beep- Video (mono/CGA Display Circuitry) Issue.

Hi, what you have not tested for isolation is your power supply, re-seating of processor for 20 minutes, cmos clearing or battery removal and mother board swapping. If all your isolation seems futile the worst is the mother board.

Hey im having issues ive had before but fixed easily i just cant remember how to do it. I connect my PS3 through hdmi on my dell W3201c tv, however, now it is saying OUT OF RANGE CANT DISPLAY THIS VIDEO...


Have you tried to reset the PS3's video manually. To do this you turn the unit off at the power supply. Turn it on. Press and hold the power button. You should after a lil time hear a series of beeps. Soon the system shoudl turn off. Turn it on with one touch and it should reset the video for detection mode and then select the monitor by itself.

No sound regardless of input. front panel lights up and functions as per inputs however also noticed pwr supply fan and internal heat sink fan do NOT turn on. Any debugging tips appreciated! Thank You...


The power supply has to be on to some extent or it wouldn't light up.

Does it tune FM? That would indicate some life.

No sound? Is it Muted or a tape Monitor selected inadvertently?

Processor Reset

In the rare case where the unit's operation or the displays seem abnormal, the cause may involve the erratic

operation of the system's memory or microprocessor.


To correct this problem, first unplug the unit from the AC wall outlet and wait at least three minutes. After the

pause, reconnect the AC power cord and check the unit's operation. If the system still malfunctions, a system

reset may clear the problem.


To clear the AVR 335's entire system memory including tuner presets, output level settings, delay times and

speaker configuration data, press and hold the Tone Mode Button (5) buttons for three seconds. The unit

will turn on automatically.


NOTE: Resetting the processor will erase any configuration settings you have made for speakers, output

levels, surround modes and digital input assignments, as well as the tuner presets. The unit will be returned

to the factory presets, and all settings for these items must be reentered.


If the system is still operating incorrectly, there may have been an electronic discharge or severe AC line

interference that has corrupted the memory or microprocessor.


If these steps do not solve the problem, consult an authorized Harman Kardon service center.

1000 VA 600W-S/N:20436760610. Unit failed after


I have gone through a few UPS, Im lucky to get 3 to 4 minutes if my power is cut.
I think most people plug too much into the UPS sockets.
The Battery backup protected sockets cant take the drain from everything over a prolonged period of time.
The nature of rechargable batteries means that when plugged permanently into a power supply they get damaged (li-on batterys especially).
Im afraid i cant help with this UPS, looks like you need a new 1.
I now only have my PC/Monitor/modem and router plugged into the UPS protected sockets.
Speakers / printer and other stuff are plugged into the unprotected sockets.

When I turn on my receiver, it automatically turns off and the power button flashes red. Prior to shut down, the receiver display notes "Tuner Ext. In" What's the problem? It has worked p


Protection circuit turns off the unit because of critical conditions- wrong power supply voltages or one of the power amplifier channels is bad. First, visual inspect the power amp board near the heat sink for burned resistors, test outputs for a short. If there are no problem you may try to turn the unit on and you have several second before it shuts down to check power supply voltages and power amp output voltages and bias, then ... Long story you'd better take it to a repair shop or repair at ebcelectronics.com

Monitor on HP Pavillion a656x---blew up the power supply--had an extra and installed it--when machine was turned back on--monitor displays "VIDEO CABLE CONNECTED?---what am I going to do----help!!!---


First thing I would do is try the monitor on another system to see if it's in the monitor or computer. Next would be to fire it up and see if you hear a beep from the motherboard. Most consumer pc's will come with a small speaker that sounds on startup. If you don't hear this beep it could be indicitave of a fried motherboard.

But it sounds to me like your video card or onboard video was messed up when the power supply conked out. If it's onboard video you may be able to switch to a video card. If it's a video card you may need to replace it.

Also check to make sure there are no loose wires, that your video card is seated firmly, and that your connectors are all snug. If none of this works then you're most likely looking at a motherboard replacement.
