T2341 won't display on monitor

My pc died on me awhile back. i fixed the problem by swapping out the power supplies. now the on board video card doesn't look damaged but the monitor won't display. is there anything i can do with the motherboard to test the problem?

the monitor does work for sure.

there is a red light on, located at the upper right hand corner of the motherboard. never noticed it when it was working so i'm not sure if it's an error light or not.

I think your motherboard is bad. We would replace both the power supply and the motherboard at the same time when this would occur. You may be able to find a motherboard on ebay.

My computer has no display even my RAM is new,,how to fix this


could be the video cable, video card, motherboard, monitor input settings or monitor hardware failure. start with swapping the monitor cables, then swap the monitor, then look at the video card (see if you can update the driver or swap the video card).

I Have A HP Pavilion a6300f And When I Cut It On I Get Nothing From The Video Port Nothing Pop Up On The Screen No Picture The Screen Stay Black As If The Monitor Never Cut On. The Monitor Works I Have...


Sounds to me like you're having one of two possible problems, first possibility is the video card burned out, second being the power supply died out. When you turn on your computer do you hear your harddrive make any sound(usually hear a bit of a louder sound similar to when you first put a cd in the disk drive) if not then it might be your power supply died out, if everything sounds normal then it might just be the video card. There are ways to swap out those pieces, but wouldn't recommend it to you if you're not too tech savvy, so what I suggest is you send it back to HP if you're still under warranty and see if they fix the issue for you.

If you are willing to try and fix it yourself you can order a power supply and/or video card from websites like www.tigerdirect.com or www.newegg.com, and to learn how to replace the parts go here(for video card)http://www.youtube.com/watch?v=Lh_rwIbVNrQ and for the power supply go here http://www.youtube.com/watch?v=UzolRkN7Eew

Screen bleeds into white after coming out of sleep mode. Turn on an off a couple of times and screen is fine. Is it my video card or is my monitor dying?mag FP-2226AFW 22"


guest, FP2226AFW may have internal "switch-mode-power-supply" problem. Swollen electrolytic filter capacitors or "thermally fractured" component leads to printed circuit board solder joints that will need to be "reflowed" to restore unit to normal operation. Prove that problem is monitor by swapping-in a known-good monitor to your pc first!!! If pc is ok, then 2226AFW unit will need "tear-down" and Inspection" of it's "switch-mode-power-supply/cold-cathode-fluorescent-lamp INVERTER power supply printed circuit board. Do some reading in my fixya profile and those of other CCFL back-lit lcd monitor tech's and you may just find a solution. All CCFL back-lit lcd monitors of the same basic design and functional operation. 12fixlouie

No vedio


swap monitors if monitor is same dell brand then its the monitor. otherwise you can buy a Video card PROVIDED that you can disable from setup the MOBO video card, and install drivers, also speaking of drivers try uninstalling the video and monitor drivers first !! the do mon swap, finally new vid card .

funky things can happen to drivers, esp improper shutting down windows like flip a power switch or not having a UPS and computer shuts down during a power outage or storm. seen this happen as well.

Pc starts and runs but wont boot up monitor shows no signal


1) When you turn on the computer, watch and listen for:

a) power supply fan, (power is on)
b) chassis lights (power is on)
c) ticking sound during memory test
(the BIOS POST is running)

d) beeps or rhythmical error codes
(POST failed, bad CPU, CHIP set, memory or video)

e) Monitor either comes on, displays garbled video,
displays a No Sync or No Signal message...

No depending on how far it gets:

Check power supply, cables etc.
Check video cable.
Check monitor with a different PC

Now unplug the power cord, with the computer still
on, this will help drain any internal capacitors.
Wait 5 minutes, then shut off the switches,
and open up the box. try the following,
one at a time:

2) Remove all I/O cards except the video card,
and don't plug them back in until the problem
is fixed. Unplug all the ribbon cables from
the mother board as well:

Hard drives, CD drive, floppies etc.

Make sure you make notes about how to plug it
back in, and cable orientation !!!

0) Re-seat all power cables: Red, Black Yellow harnesses.

1) Unplug and re-seat the video card

2) Similarly, re-seat all memory SIM/DIM modules,

3) Re-seat the CPU

4) Replace the video card

5) Replace memory, CPU or whole mother board,

Plug the good parts back in one at a time,
and test the machine.

Save for the power supply, there really is NO way to test
and isolate a bad module except by swapping/ trial and error
because of inter-dependencies.

For example a bad I/O card, any I/O card, can short circuit
the I/O bus, causing all other plug-in cards to stop working,
or even the main mother-board to freeze during the POST.

A bad power supply ditto.

A bad memory chip ... ditto.

The type of electronic instruments required to actually
test modern computers running at Gigahertz speed cost
hundreds of thousands of dollars, some cost millions, and
are only available to hi end manufacturers

Even the power supply will not power up for a voltage check
if the mother board is bad, although you can use a jumper
on the green wire to ground to force it on, when you unplug
the power connector from the mother-board, if you are brave.

Computer shops carry a lot of spare parts, and their service
department has gutted computers rigged up as test jigs.

They trouble shoot your system by either plugging your
stuff into their jigs, one at a time, or by plugging known
good components into your computer until the problem
is fixed.

This if of course possibly dangerous, since one bad part
can also fry other good parts that plug into it, or that it
plugs into. The compute shops, of course charge you
enough to make up for this.

If a computer is partially operable, it is also possible to
run software diagnostics.

If not, swap and pray is the only way.

Hope this helps

Please rate my answers, martin.

Motherboard detects nothing


anniegms, I had the same problem with a new Asus board running a Dual Core Duo Quad processor. The boards BIOS was not updated to handle the Dual Core Duo yet. I had to switch processors to a P4. Use a different PC to make a BIOS update disk. Update the BIOS and switch processors back. But I had all the same symptoms of yours. However I did/do have a PCI-E XFX Fatality (Nvida) based graphics card. I would check or swap processors, it sounds like the board is waking up but not the processor. Just my thoughts.... PCdok
