You could first try a hard reset by unplugging it for 8 hours and plugging it back in which is a hard reset. Dell had you perform a soft reset. I don't think either will work but it never hurts to try.

I believe that it may be a problem in the microprocessor circuit

All parts could be bought through dell

The first thing I would try though, is calling Dell and see if they will replace it for you for free or fix it has I have seen them doing this for many people even out of warranty. So be persistent and see if they will replace this for you. 1-800-624-9897

Let me know how everything goes and if dell won't do anything for you then have a look at the boards for bent pins if the microprocessor circuitry checks out fine.

good luck

Firstly i would suggest you to perform Self-Test Feature Check (STFC)
Your LCD TV when used as a computer display through DVI and/or VGA connection provides a self-test feature that allows you to check whether your LCD TV is functioning properly. If your LCD TV and computer are properly connected but the LCD TV screen remains dark, run the LCD TV self-test by performing the following steps:

  1. Turn off both your computer and the LCD TV.
  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 LCD TV.
  4. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the LCD TV cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually

This box also appears during normal system operation if the video cable becomes disconnected or damaged.
Turn off your LCD TV and reconnect the video cable; then turn on both your computer and the LCD TV.If your LCD TV screen remains blank after you use the previous procedure, check your video controller and computer system; your LCD TV is functioning properly.

OSD Warning Messages

A warning message may appear on the screen indicating that the LCD TV is out of sync range.
See Specifications for the Horizontal and Vertical frequency ranges addressable by this LCD TV. Recommended mode is 1280x 768 @ 60Hz.

    Try disconnecting cables and turn it on again if its not going to show anything still, try to reconnect cables from the back- make sure all cables from dvd and tv line are plug in tightly...

    i think you have to wait til it feels like showing an image, turn master power
    on/off and that should work.

SOURCE: Dell w3000 has green power on no video just audio only

Had same problem as described by others, green light, audio, but no picture. Decided to look inside. Layed the TV face down on three textbooks (1 at top & 1 at left & Right) so that back (9 large screws & 2 small screws) could be removed along with stand. From the power supply (board that 110v AC plugs into) there is a cable connected to a circuit board on the left (again looking from the back of the TV) covered by metal shielding. Unplug this cable clean the male contacts with a miniture wire brush (bought mine at Home Depot) & plug the cable back into the socket. With rubber gloves (just to be safe) plug the AC cord into the back of the TV & wall and turn on your TV. The bulbs should activate in 7 - 8 seconds. Reassemble the back of the TV & install the stand. Enjoy your TV Doug

Dell w3000 no green power light unit will not power on


This was a product malfunction with that TV. Dell ended up paying out $$ in a class action suit over this product...I think I got a check for like $30 in the end. There is no fix I was told...but try to toggle the master switch, or unplug and plug in again - that often times worked for me. In the end I bought a new tv though because the frustration level was too much.

Dell w3000 will not turn on at first try. Takes many attempts turning it off and on before video comes up. Audio always works and green light is on.


Faulty caps, if you take the back cover off of the monitor, there are 2 boards on the outside edges of the left and right of the monitor. these boards are covered by metal shields. remove the 3 screws on each board shield and slide them off.(careful this can be tricky) on the boards are 2 capacitors that need to be replaced. 4 total, 2 on each board. the capacitors are 150uf at 35 Volts. go to your local electronics repair shop to get the parts and tools needed to do this repair.
make sure to get the polarity of these caps right. stripe side on cap goes to the minus.

W3000, power and audio but not picture


Yes I tried it and now I have nothing, not even a green light. So much for that. I have 2 of these sets. If you never unplug them from 110 I never have a problem. Un plug them and wait 2-3 days and nothing.
Any lawyers what to take this on?

Try turning the master power on and off a few times. Give it a few secs inbetween power offs and that should work. It's worked for me. Sometimes it takes longer that other times to show a picture.

It's repairable, sounds like the main board, but try some other cables and sources to see if the same thing happens
