I recently bought a refurbished HP w2408H LCD monitor. It flashes red, blue, green, black, white repeatedly, about 1 second per color, when idle.
No amount of changes on the built-in LCD menu change this, nor do any changes on my computer (in fact, the flashing colors happen even when the monitor is disconnected from the computer).
Is this some kind of factory test mode or burn-in that is required? Any way to disable it (or any idea if it turns off at some point)?

It is a factory test mode and can be reset by doing a "factory reset" from the Menu button (On Screen Display)
Sorry that it got out of the factory that way.

Hi there, i'm experiencing the same problem with the original poster so i don't see a need to start a new post.
What happened is that i've just bought HP LP2275W monitor after reading all the good reviews. However to my disappointment when i first set everything up all i got is a "no signal" screen and the monitor went to sleep. I've then rechecked all connections but didn't manage to get it work.
Then i played with the buttons under the screen and somehow after around 30mins the screen is showing and i managed to log on to my Ubuntu and installed the driver, set the resolution and refresh rate to the correct one (off the top of my head i think it is 1680x1050@60hz).
Anyway the next day when i switched on my pc the monitor went "no signal" again. This time after numerous reconnecting the cables, rechecking the connections, toggling the buttons under the screen, i couldn't get it worked. The monitor went to sleep and didn't wake up unless i switch i off and on again. I then pressed the "reset" button for a few seconds and to my surprise the monitor "woke up". But it's now having this red, blue, greeen, black and white flashes.
Is there any solution to the above problems? Or is the monitor i bought a defective one? Should i arrange for a return?
Appreciate any sort of advice. Cheers!

btw not sure if this matters but the following is my computer specs:
Intel E6320 Core 2 Duo processor, 4gb DDR2 RAM, Ubuntu 8.04LTS (OS), Sapphire HD 2600XT 256Mb video card...

I was able to solve this by turning off the "burn-in" on the Innolux factory menu. However, I can't figure out how I got that menu to appear or how to get it to show up now, so I can't pass that on to others. The Innolux menu appears directly under the Main Menu.
Does anyone know how to get to it? That would help others.

I have exact the same problem as gidyeo!!
My LP2275W is stuck in test mode and there is no way of escaping it...
I tried to unplug everything, pressing the buttons short, medium and long time, I changed the connection from DP to DVI.... no reaction.It color-cycles on and on. :-(((((
At the moment I can only point to HP an say: WTF??!!! I always thought, HP-Products are expensive but worth it... until today!!!
I hope someone can solve this problem!!!
Big Thx in advance anyway!!
The long story:
I´m using a PNY Quadro CX card and first connected my both displays (1st: HP LP2275W 2nd: Philips 200W) to the Displayport-Connectors.
The HP directly, the Philips-display by using the adaptor from DP to DVI.
The first time I powered up, the HP told me, it got no input signal but after 10 or 15 sec it came up with: displayport: active.
But the resolution was limited to 640x480.
The other dispay works fine on DVI...
I thought that resolution-issue can be controlled via driver or OS so I installed the display-driver provided on the CD.
After rebooting nothing had changed. When I opened the OS-display config it let me only select between 640x480 up to 1280x1024px. No 1680x1050 option. The same with the NVidia Display Config.
Using the HP Display Manager didn´t help but it also only detected the Philips display.
Trying to install the monitor INF failt too because WinXP x64 said that the connected display is a generic display not a plug´n´play display.
Already anoid about this I started Everest UItimate 4.60 and checked the display settings. It only showed me the Philips-display, the HP has disappeared.
After searching many forum posts I came to the conclusion that HP f**ked up the DisplayPort-Connection and it will be better to use DVI instead.
After reconnection the displays to DVI the LP2275w stayed black. After pressing the Input-button and selecting the DVI-Input the display switched to the test-mode and remained there until now!!!
The help from the HP site: "How to end test mode by making a facotry-reset" dont work!!!!
No reaction to any button, unplugging, unpowering....
I even shout with it but didn´t punch it so far.. ;-)))
I can say, I´m a very experienced user and used to change hardware but I´ve never seen such a strange behavior...
I hope HP can provide a solution for this!!!

Having received no help whatsoever from the "consumer friendly" HP since my last post, i had another go to revive the monitor, and it paid off.
All i did was connecting my LP2275W to my 6year old laptop's vga port. Thank God the flashing screen stopped and it picked up the signal from my laptop. I then quickly unplugged the cable from the laptop and stick it into my pc and voila it's picking up the signal (again)!
Having used the monitor for the past few weeks i can say that this is a cracking monitor but with a few fatal flaws (which is very common from what i read from other forums):
- dvi to vga connection is not reliable, i still get occassional "no signal" message.
- i then switched to dvi to dvi, but the infamous flickering/flashing horizontal blue/red/green light appears occassionally (they'll disappear after around 15mins of usage usually)
- my monitor takes forever to wake up from sleep, again a very common problem.
more can be read from the following url:
Now all i'm thinking is to get a replacement from HP, but having searched on HP's website for monitor warranty info i couldn't find anything? i would appreciate if anyone from UK (esp. Midlands) could tell me how to go about getting a replacement monitor with HP? (the receipt is gone so i couldn't return the item to the vendor)
So much of "making the computer personal again" eh...
ps. i would have gone for Dell's 2209WA (going for around £200) if i could return this...

As I mentioned above, the flashing red, blue, green, black, white sequence is not a defect; it's the factory burn-in. If you can figure out how to get to the Innolux Factory menu, you can turn off the burn-in.
I can't recall how I got to the factory menu but it might involve some combination of the physical buttons on the monitor, or it may be using the menu that shows on the screen.
The factory menu showed in the same spot on the screen as the regular menu.
Hope that helps.

Thx for the workaround, I will try it with my old notebook too!
I had the same idea but I tried to connect my Panel to my other PC on a Radeon 1900XT via DVI and still got the color-test.
Maybe it will work in my ugly old notebook ;-)
If you want to get a replacement monitor you should go to the HP website an look for the SUPPORT CASE MANAGER. After registering you can enter you Productdetails and tell HP whats going wrong.
I recieved answer a hour after I postet the case wih "Replacement Kit is on delivery"!
Next day I got a replacment display but unfortun. it´s one of the "Assembled in Czech"-units with the annoing loud sound and it also was a used one, because the OSD reads 125h of Backlight duty...
SHAME ON YOU HP!!!!!
I immediatly started another case and insist to get a brandnew, bugfree display.... no reply so far.
Hope I could help!
I just tried to conect it on my old notebook via the VGA-Connector but still no reaction from the panel... too bad!!!!
