I have this tv, and have had the EXACT problem. my solution was simple. 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.

This is the way all of these fail. Don't buy Dell TV's.
Try this internet posted solution.
Turn on TV with remote control, if the TV does not light-up, find the Main Power Switch. Turn the switch off, then turn it on, the TV lights-up. Probably caused by poor contacts due to age and low quality parts.

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.

My dell w3000 tv wont power on


There are likely bad capacitors on the power board. You will need to replace 4 capacitors, labeled c101, c304, c305 and c404. I used 3 50v 33uf and 1 50v 47uf capacitors. The originals are 35v 33uf and 35v 47uf. Replacing these should fix most power board issues.

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.

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
