SOURCE: 23 inch lcd tv by dell wont turn on as if no power

if this is a DELL W3201C read this.

Have the same model and same problem
probably It is a bad inverter board, in my case one of the 16 transformers is burnt out on the inverter board. still trying to find a replacement component. if not replacing the board is the only option or getting the inverter board repaired.

by the way, this TV has a Samsung panel: model LTA320W2-L03. so it needs parts for a Samsong not a DELL.
DELL does not manufacture or fix them becuase they don't make them

SOURCE: Dell W2600 TV

I have had the Dell W2600 for about 4 years. My remote for the Dell stopped working after 16 months. Since I was using cable I used the cable box remote. However, about 6 months ago a dark shadow appeared on some parts of the screen but the tv was still viewable. Shortly after, my power light would suddenly go out and then come back on after a minute or so. The problem got progressively worse until tonight it was off for most of the show I was watching and would come back on briefly. I popped the rear cover off and removed the metal shield and found most of the wires on one of the wire harness coming from the power supply board burned so badly the insulation was gone and the plastic connector assembly on the board melted. Because of the nature of modular board construction the power supply board and wire harness would need to be replaced and that doesn't necessarily mean the cause was fixed! To me this is a safety hazard. The TV is definitely out of warranty but I wouldn't expect this type of hazard problem. FYI, the parts I can read are made in China....what's new!

SOURCE: I recently received a Dell

first check with a different cable , if it still doesnt come on , then you have to open it up and look for a burnt or cold solder where the transformer is ,also look around for any other solder. hope this helps AJ

No sound, picture perfect. w3706mc. works first 6 months


Hook an external Stereo Receiver (or surround sound system) up to the Audio Out jacks on the back of the TV... this should allow you to hear the sound again.
Hope this helps.

Just out of warranty Dell TV W3706MC,two years old


Sounds like a bad video board. No easy way to fix a bad video board. It needs to be replaced. That is why the repair shops will not fix it; they do not stock video boards for all models. And it is a pain to track one down all of a sudden. Once a warranty is up, you are running on bonus time. Electrical components have a definite lifespan. It is possible to recover some money by selling it "as-is" online somewhere. You could get 200-400 for it broken, pretty easy I suppose.
