Dell GX280 no display

Hi my Dell GX280 displays nothing on screen (screen light stays amber).
PC power button solid yellow, no diagnostic lights, & fan runs uncontrolled.
I have disconncted all disks & removed plug in boards, metered power supply (ok) tried memory 1 board at a time then got hold of a new motherboard but fault still the same. Do you think a second faulty MB or
am I missing something? Your opinion would be appreciated.
Regard Brian

    i am having the same problem with a gx270, or two of them actually. i have changed power supplys, mainboards, memory, processors, video cards and unplugged everything not needed to start into the bios. the computer starts and shows video on the screen then after a few seconds, the video goes away. the problem is exactly the same on both computers. i have even tried beating the computer with a sledge hammer. that didn't help either. any other things to try?

I solved this on a Dell GX280 by removing the CPU and then reseating it in the socket. Also cleaned cpu and heatsink and applied new thermal compound.

Re-seat the CPU and re-apply new compound. Worked without issue for mine. If it were the PSU you would get flashing amber PSU.

Reseating in the socket work for a GX270. When I did that, I noticed that the processor was bad plugged (when I remove the cooling, the processor also came throught)

Now it is working. At first time I thought it was the capacitor stuff, a lot of info on the web about that. I checked the CAP manufacturer (visual inspection) and I realice it was the replacement one, not the Nich... defective CAPs.

Thanks,
Danilo.

I had this problem as well - solid amber light and no power-up. I resolved it like "NoNaym" said by re-seating the processor. I should have tried that hours ago because I tried just about every other gymnastic I could come up with before trying that. I was SURE it was a power supply issue but in the end it appears that it was the re-seating of the processor that did the trick (for now anyway!)

Power supply didn't fix mine, neither did swapping processors, video cards. It has to be a motherboard issue. The op never mentioned getting a *new* motherboard so I'm guessing its another bad one. but thats just a guess.

How do I fix problems of Dell computer 780 with power light yellow and black screen?


getnet,
What do the diagnostic led lights show. The diagnostic LEDs are located on the front of the chassis next to the power button. These diagnostic LEDs are only active and visible during the POST process. Once the operating system starts to load, they turn off and are no longer visible. Below is the manual that provides information on what the led pattern shows to help resolve the issue.

Dell opitiplex 280 is not giving display. first of all his fan speed to much high and then after 4 or 5 day its display disappeared. its just picking now power and fan also start with high noise and...


OK, I use GX280s as home servers and ran into a similar problem with one of them...

The problem may be serious and not worth fixing (motherboard).

Turn power on
Fan(s) come on full power, sounds like a jet engine, or eventually gets that loud.

See if you power light has gone amber.

You get nothing on the screen, no Dell splash screen/post, nothing.

This is what I posted a while back concerning the above. Obviously I cannot bee 100% certain as I do not have your box in front of me. This a known issue.

--------

See if the power light goes amber after power up. I had (have - still siting in my basement) one that did same. Power up, fans go full blast . Power light goes and stays amber. This is USUALLY caused by bad capacitors on the mother board. Known GX280 problem going back. If you look on the motherboard, the capacitors should have flat tops and not leaking. If the are rounded or leaking, the MB has probably gone bad. Bottom line this is usually a defective motherboard. Mine was a bad caps issue, you issue could be different, but it does sound like the motherboard.

You can google "gx280 solid amber light loud fan" and see the issues. Here is one link.

Dell optiplex gx280 desktop when turn on just orange light even fan not working, what is the prob?


Normally a solid amber light indicates there has been some type of hardware failure. Possibly power supply, possibly motherboard.

We have around 30 units of DELL Optiplex GX280 having mother board failure. It was more then 3 years old already. Once the turbo fan become noisy then it will gone dead.

Amber light flicks once or twice no sound from fan or anything? What do we need to do


If the power button is a solid amber it is likely a motherboard due to a failed capacitor (Check the capacitors on the motherboard see if any tops are bulging)
If flashing amber, most likely a failed power supply

check on system lights... what are the diagnostic lights telling you??
if the 4 lights are off you may have a problem with the led itself or the powersupply is just messing with your head.
