Windows 7: No sign of output from computer

No sign of output from computer

I have a dell inspiron 620s as a media computer under my TV. I press the power button to turn it on, like I always do, but my TV gives no response, it continues to say no signal. I have a dvi cable running directly to my TV and I know that everything is set up right, it worked fine two days ago. The light on my mouse does not go on like it normally does and my receiver gets no audio input (I have it hooked up to my PC via HDMI). I did get it to show the BIOS loading screen just once, but it hung there for several minutes until I held the power button to try again. I'm guessing the problem is hardware related, but I'm still clueless. It could probably be a plethora of things. Any help is appreciated!

Try disconnecting all external devices and hook up a VGA monitor, wired mouse and wired keyboard.
I won't be able to help you much if you can't see what's going on with your machine. So the first step is get a base system and then go from there.

Hi randomperson1,

Welcome to Seven forums.

Please let us know what is the color of the led on power button for the system. If you happen to see the BIOS screen you should be able to access diagnostic partition as well. Check this video to perform diagnostics on the system:

http://dell.to/18xQpRy

Also, remove all the devices from the system except mouse,keyboard and TV to check if system boots properly.

Make sure there is no remavable media like CD or Media card inside the system. Kindly update your system specs here by following this.


Keep us posted with the results so we can advise you further.

The led on the power button is orange for a split second after pressing it then it changes to its normal bluish white. I left it on for four+ hours and nothing changed. I can not get the BIOS screen to pop up again. I removed everything from all the ports and drives except the display and used a wired mouse and keyboard. I would update my specs but as it will not boot I went on what I can remember. Also I took the same vga (I know I said dvi previously, I meant vga. Sorry for the confusion) cable I am currently using with my pc and plugged it into my laptop. It showed up on the TV immediately so there are no problems there. I can't think of any other useful information I can give you. If you know of anything I could try, please let me know. Thank you for helping me.

Do you hear any POST beep codes?
Quote:
Beep Code Possible Problem
One Possible system board failure BIOS ROM checksum failure
Two No RAM detected
NOTE: If you installed or replaced the memory module, ensure that the memory module is seated properly.
Three Possible system board failure Chipset error
Four RAM read/write failure
Five Real Time Clock failure
Six Video card or chip failure
Seven Processor failure

Do you hear the HD spin up?

You might try clearing the CMOS. SandeepP might know exactly how to do this, but some mfrs tell you to
remove the power cord (and battery)
press and hold the power button for two minutes

Not sure if that works on a Dell Inspiron, the other sure fire way is to remove the CMOS battery for about 20 minutes and replace it in the machine. You'll need to check the manual or search Dell, I didn't see it when I skimmed the manual.

After yu find the information - Ask first - SandeepP might have some other suggestions.

Hi randomperson1,

Thanks for your reply. I appreciate the time and effort that you took to troubleshoot the issue.

Your post is little confusing. Can you please confirm if the system worked fine with the VGA cable when you connected it to the TV.

First of all you need to isolate if it is an issue with the System, Cable or the TV. Check the system with different video cable and with different TV and let us know the results so we can advise you further.

SandeepP,

I have been using this computer in this connection set up with no problems for almost a year.

Like I said I connected my laptop (not the broken desktop) to the same vga cord hooked up to the same tv that the broken desktop was hooked up to and there were no problems. I think this is enough to isolate that it is a problem with the computer.

If you think it is necessary I will haul down my monitor and vga cable from my upstairs computer and try with that.


Slartybart,

I do not remember hearing any beeps on start up, but I will listen carefully when I get home this afternoon.

I will also try what you said about holding the power button when I get home and post the results.

I'm not sure what the CMOS battery is or where to find it, but I will research that and try that as well.

Thank you both. I will be sure to keep you updated.

Just looked again at the service manual (2nd pdf in previous post)

1) Hold off on BIOS - the manual lists that fairly early.

2) Coin-cell battery is the reference in the manual. Don't worry about replacing it yet, just pull it to reset CMOS. Again, there might be a simple "hold the power button" option so you don't have to open the hood. The manual does mention the power button to ground the Mobo, but that might not discharge the capacitors to the point where CMOS is reset.

If you read something and aren't certain, please ask first. There's a good chance that some piece of HW is preventing the POST to complete. So, you've removed all external devices (yes?) except those you need (Monitor, KB, mouse). The next step, if the beep codes don't tell you anything, is to try the internal devices (memory, pci boards...)

Since you can't get the machine up, we can't stress test the components with SW.

I'll suggest things starting with the easiest - beep codes and CMOS

Then you can try reseating components inside - but first things first.

Slartybart,

I have disconnected everything and removed the cd and sd card except for the mouse, keyboard and TV. (I've tried with everything unplugged as well, and then plugging them in after turning it on.)

I listened carefully and did not hear any beep codes. I did hear either the hd or fan spin and continue to spin until I shut it off. (I've always heard this)

When it was off, I held the power button for several minutes. Immediately the hd started spinning and then died immediately after. It did this about every 30 seconds while I was holding it down. After I had held it for 4 minutes nothing had changed.

I unplugged everything and removed the cover. I found the coin-cell battery and took it out. Should I get a different battery?

I hope this does the trick. Please let me know what I should do.

For the remainder of this exercise leave everything except KB, mouse and monitor disconnected.

Hold off on buying a new one for now. The coin-cell batteries rarely need replacing, but it is possible.


Reseating internal components: Follow the instructions in the service manual to
  • to disconnect the disk drive, then reconnect it (both the data cable and power cable)
  • to remove the memory cards, then put one (if more than one) back in the slot.
This eliminates one possible cause - loose connections

Then put the same battery you removed back in and see what happens.
