Towers don't shut down monitors. Monitors either work or they don't. Maybe the graphics card is bad (if you have one)? Please explain the problem in more detail & tell us if you made any changes to the system that may have brought on the problem. Also, why do you feel changing the motherboard is going to fix it?

I believe the correct model number for the "1920" is SR1920NX & for the "1720" it's SR1720NX.

The 1920 uses an A8N-LA board, aka Nagami2L-GL8 (GeForce 6150LE/nForce 430).

The 1720 uses an A8AE-LE board, aka AmberineM-GL6E (ATI RS482/SB400).

Notice they're based on different chipsets so if you were to swap the boards, Windows would most likely have to be reinstalled from scratch. And if you're running XP & have a SATA HDD, you'll have to know how to do the SATA installation. The HP disks or recovery partition probably won't work so you'll need a retail XP disk with the SATA drivers slipstreamed into it to be able to pull it off.

EDIT: the A8N-LA is the better board, the A64 is the better CPU. If you swap boards, make sure to use the A64 rather than the Sempron.

Hi & thank you for the reply. No upgrades have been done to my system.
Problem: I was in yahoo & the screen started displaying
a bunch of squiggly lines & then went blank.Could not cold boot or get anything
to happen.Could not turn off the tower,had to turn off the power strip.Wait a few & turned tower back on,the green light lights up on both tower & monitor,but a moment or two,the monitor color will change to a yellowish color & will stay that way.Then I can not turn the tower off.Have to use power strip again.
I have another good monitor that works well with it's tower aka. sr1720nx.Changed the monitors,plugged back my tower & turned it on.Same thing.Tower shows as if it's on,monitor color is green & then will change to the yellowish color.Tower will not turn off so I use the strip.Both monitors work fine.Am using the 1720 system with the monitor I use with the 1920 system as we talk.My 1920 has all my info including windows & 1720 is as bare as can be so I want to use the 1920.
I have taken my 1920 for a diagnostic check & the mboard is what they believe is
the problem.They said,Since the tower lights,the p supply is good.Since there is no
output,the mboard is bad.I would do a disk recovery on my 1920 if it would fire up &
put it on my 1720.Really don't know about the graphics card.

✔ Best Answer
"Since the tower lights,the p supply is good"

Not necessarily so. The PSU has 3 main voltage rails, +3.3v, +5v, & +12v. Of the 3, the +12v is the most important. However, if any one of the 3 fail, the system will not boot, but there may still be enough power to light a few LEDs or spin a few fans.

Do you have another PSU you can try?

EDIT: to power off the tower, there's no need to use the power strip, just press & hold the button on the tower & wait for it to shutdown.

I have the psu from the 1720 I could use.Will it have the 3 main voltage rails ?
I have held the button in for 10 seconds
without it shutting down & that's why I used the strip so maybe it is the psu.

Can always try getting a spare PCI video card and seeing if you can get video from that. I am assuming your video is built-on to the motherboard. I would try to stick with 1920 hardware vs the 1720 from the information the first poster replied with.

Could definitely be the PSU, or could be the video chipset on the board, or could be the board.. Need to actually test the equipment (PSU testing, MB tester) to get that answer. Or test with comparable working equipment.

Thanks for any input.

I want to thank you for yr imput.I have a problem & you've help me try to solve it.Per yr suggestions, I've tried but can not not use anything from my 1720 system to transfer to my 1920 system.
Going to purchase a p supply for my 1920 & see if that solves my problem.
I thank you again.
