2405fpw yellowish/brown hotspots fixable?

Hi dav2012,

Welcome to the Dell Community

I understand that yellowish-brown smudging or hotspots appear on the monitor. I would request to try the following steps depending on which I could resolve this issue for you.

Step 1:- Change the color settings on the monitor. Please select the menu button on the front panel. Select “Color Settings>> Select “PC standard preset is selected to obtain the default (factory) color settings”>>Turn the monitor off and then turn it on.  Please check if the yellow spots appear.

OSD menu & select The MENU button is used to open the on-screen display (OSD) 

Step 2:- Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. Run the monitor self-test by performing the following steps:

1. Turn off both your computer and the monitor.

2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog (blue connector) cables from the back of computer.

3. Turn on the monitor.

4. Check if the yellow or brown spots appear during this self-test.

5. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.

The floating 'Dell™ - Self-Test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.

Please try these steps and let me know of the outcome.

Glad to be of assistance

Thanks,

The results are the same as in the picture I have posted. These are not burned pixels, but seem to be large heat spots on the screen or dirt/dust inside of the lcd. I'm not sure which.

Hi dav2012,

Thank you for your response

I understand that you tried the steps  that i requested you to perform  and  the spots do appear on the screen during self test. I would request to add me as a friend and send me a private message with the ORDER number, CUSTOMER number or Service Tag for the Monitor . When you send me the information , I will check the  configuration and warranty status  of the monitor and revert with the best possible resolution

Thanks,

Manpreet

noseyPete,

I have not seen any fixes for this in the field. Dell does not repair monitors or sell internal monitor components. We do not even have monitor repair/disassembly documentation. We simply replace them while under warranty. You can try these 3rd party repair sites and see if they sell monitor components:

Hi there,

I have the EXACT same spots showing on my faithful 6ish year old 2405FPW. The same size, in the same places, including the edges.

I notice this pic is from http://www.rage3d.com/board/showthread.php?t=33980146 so clearly this is a common fault that develops with age.

Does anyone know of any fixes or suggestions? It's been a great monitor and I'd hate to lose it.

Thanks for your response, Chris.

It's a shame there's no 'known faults knowledge base' or something to help others in similar situations. It's been a great monitor and I'd love to keep it going!

Guess I'd better start looking for a new one...

I bought a used monitor that had the same issue. I thought it was the bulbs so I bought replacements and installed myself. However, what I found was that the white reflective material behind the bulbs was yellowed - specifically the plastic brackets that hold the CCFL tubes. The dark spots correspond to exactly where the support brackets are. I don't know that they can be replaced, so the only real alternative is to go in and paint/cover them with something non-yellowing that's basically as reflective and white as the backing. This was obviously a design flaw.

While there was film of nicotine/smoke that told me it was used in a smoking environment. A cloth, Q-tips and rubbing alcohol took care of the film on the reflective backing, but the yellowing on the bracket is not removable - it's likely from the UV exposure. 

Good luck, Paul

P.S. Also be aware that the clips that hold the bulbs get brittle with age and may crack, also the result of the plastic brackets that degraded under UV exposure. Suggest a drop of silicone (non-yellowing) if that happens.

MediaVortex,

I would not call this a "design flaw". The 2405FPW was released in 2005. I think the yellowing is just due to them being 9 years old. How many hours of usage could there be in 9 years.
