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.

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

It was a bum tv. Dell paid a class action suit over it. You need a new tv. Sorry.

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.

Old tube-type tv?...check H/O (Horiz/Output) transistor for internal short or burnt signs around it. Hope that helps.

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,

Hello,

If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.

Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.

If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.

TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.

The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.

So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.

If the above is contrary to your question, please let me know and make your question very clear in the case.

Regards.

Tienes problemas en los flexibles cables. Tienes que resetearlos, o sea sacalos y metelos en su conector. Si no mejora el problema, tu panel esta defectuoso. si tienes otra pregunta avisame.

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

I need the exact brand and model # of your TV

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.

On the bottom of the tv there are two boards that buffer the vertical sections of the screen. You need to take the tv apart (if you're able) and look for burnt sections on the buffer board below the problem area. Once you replace this section of board you will have no problems. The problem is happening once the board heats up from normal use.


Hope this helps :)

If it's failing to turn on, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core (no laminations as with a line-frequency part) transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.

Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.

If you see signs of overheating such as discoloration of the board material, the PSU may not be repairable but if you can find a part number on the board, you might be able to buy the power supply from the mfr. and install it yourself but it will likely have the same problem eventually unless they have altered the design or improved component quality.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the main power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload and the power supply for the backlight may be at fault.
