Question about Dell W3000 30 in. HD-Ready LCD Television

4 Answers

Dell W3000 lcd TV picture will not come on the first time power is turned on.

Dell W3000 lcd TV picture will usually not come on the first time power is turned on but will eventually come on after 2 to 8 times of turning it on and off. However, the sound will come on immediately and every time I turn it on. Once the picture comes on it stays on and the set works perfectly. Note that there is no consistency here. Sometimes it comes on the first time, sometimes it takes almost 10 trys.

    The TV is not new, I cannot take it back nor is it being used as a computer monitor.

    I can't perform this test. Any idea how much this replacement should cost?

The failure on this Dell W3000 is found in the power supply assembly, specially around the 5VDC line due to dry or leaky capacitors. Their values should be 1000uF/16 volts. If you have a capacitance meter they can easily be found when you measure the value or you can see them bulging on top.
The audio is getting Its power from a 12VDC source that is why the audio works instantly.
Let me know if you need more assistance.

    If you are unable to troubleshoot the power supply module. It looks like the only option is to replace the power module.

    You can call Dell or inquire here for the power supply. It could also have a defective inverter boards.

HI,

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

ONE: Check the line cord. Wiggle both ends near the molded part.
TWO: Make sure you have power in the outlet by plugging a lamp into the same exact outlet.
THREE: Do a hard reset; merely unplug the line cord but leave it unplugged for 4 hours before powering up again.

The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.

If this does not solve your problem then the only solution to fix your the problem is to get it repaired by a technician

Goodluck,
Please don't forget to rate the solution.

Dell W3000 LCD TV has sound but no picture. In the past have had to turn on and off several times but this no longer works.


The problem of the picture not firing up right away on the Dell w3000 display is a manufacture defect in the LCD Inverter Boards. Could be master and could be slave that's failing. Most likely Master, but I suggest replacing both master and slave just to be sure. Stay away from pulled parts sold on ebay for this fix. You'll just be buying the same problem most likely. Try http://www.lcdparts.net/InverterDetail3D.aspx?ProductID=1921 I have ordered from them in the past they are reliable and handle RMA's quickly. This is a huge plus if you run into another problem trying to replace. They want 149.00 and the fix requires very little skill level to replace. Just have to decide if 149 bucks is worth it, or is it time to go for the 50 inch. hmnmm. Good Luck,

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?

Dell W3000 display issue - logic board or inverter?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Dell w3000 & PS3


This may not be DVI issue.
I connected DVD player HDMI ----> DVI ( Dell W3000) LCD TV.
Later I found that Dell TV version of DVI does not support HDCP protocol ( High Definition Content Protection protocol). So I could not play HDMI to DVI movies from my DVD player instead I use Y Pb Pr -- this works ok.

Hope this helps... I am not use PS3 enforces HDCP - I assume Sony linked with Sony Pictures would enforce HDCP on HDMI cable.

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.
