Dell W3000 display issue - logic board or inverter?

I've been reading many posts about the issue I have been having with my Dell w3000 for years now (have to turn tv on and off many times to get picture to show up - green light and audio are not a problem and always work). It seems as if there have been many possible solutions - the two that sound most reliable are replacing the inverter (http://www.lcdparts.net/LCDTVInverterdetail.aspx?InverterOriginal=6632L-0048) or replacing/fixing the logic board (http://www.lcdrepair.us/w3000-logic.html). Both options cost around the same amount and although the TV might not be worth as much anymore, I am still committed to fixing it as I have no other issues with picture quality, etc.. Can someone with expertise help me figure out which part to by? Thanks so much in advance!

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.

HD Ready does not mean that it is HD compatible without the addition of an optional part.
The title only implies that it can be adapted to HD reception.
If you did not purchase it with the set, check your user guide to see what you need to make it whole.
You may have to seek this add-on on eBay since it is not guaranteed that Dell will still offer it, or you can buy the convertor (with a $40 coupon) that many sets need.



You can order (backorder from what I read) the coupons here:


Convertor Coupons


After surveying many of the set-top convertors, I bought Zinwell ZAT-970 units for two older sets not currently in use but will now serve as backups when our sexy flat panels die like so many.

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.

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,

I have no 24v and 12v on a dell w3000 tv


Incase the inverter board has shorts circuits that caused the 12/24vdc power supply to shut down, try disconnecting the power cable from the power supply that goes to the backlight inverter board to see if the 12/24vdc come back, if not, you need to find out if the power supply is getting the PS_ON signal at one of the power supply connector (you will have to trace out the board to see which pin that will be unless it is labeled on the Power supply board). No bad DC filter caps that you can see?

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