I have a dell W3201C 32" lcd tv that i love, picture is great, no dead pixels or lines, but i am having an issue with the tv. after its been on for 45 minutes to an hour, the screen goes black. the power button is still illuminated, however the tv stops functioning. if i turn it off and turn it right back on, it works for another 5 minutes and goes black again. if i leave it off to cool down for a while, it works again, but only for about another 45 minutes to an hour. has anyone had this problem? any advise on how to fix it?
I removed the black backing from the TV set. My TV was doing the same thing. It would shut down after 2 hours or so and the power light would remain on. Once you turn it off then back on it would do the same thing, only more frequently. After taking the back panel off the TV stayed on 12 hours before having this issue again. It is running much better and I can only assume it is happening because of very very poor heat dissipation design. I am also going to blow out the insides with compressed air. I haven't had time to for that yet.
Its the power supply!!
well i migrated to this issue from having no sound and video with just the power button illuminated. I replaced the power supply with one from an online salvage store and it worked fine for about two hours and then it shut off, turned it back on and then twenty minutes later off again...repeat... need an electronics person to trouble shoot and trace which resistors and or capacitors are overloading. anyone??
I had the same problem with mine and eventually it wouldn't work. Dell sent a refurbished unit and it did the same thing. My warranty expired and the basically said there was nothing that can be done............

Coaxial cable does not carry video signals but rather rf-signals
To use coax you will have to tune like you are searching for a signal from your aerial..
If you prefer to use video then you will have to use a video cable either rca or hdmi. you can then choose video or hdmi from the remote
I bought two sets at the same time and the sound has gone out on both, So far no luck with Dell or a soloution. The post on attaching a surround system sounds like a good idea, but I can't get this to work. With a little feed back I'll create a site to log how many have this problem, a few can be understood, but from what I'm reading the sets were defective when shipped and Dell must know of the problem,
I Have a Dell Model # W3201C With same problem since i am a tech.
and am experienced on LCD's after taking set apart 1 found Problem's
on Hi-Voltage board that power's the front panel . seem's that the 24 volt
line from the main power supply is bad maybe even one of the surface
ic's is draging the line down.... don't know if the hi-voltage board is
available or not this board would probably fix this problem... also would
like to know it's part # if it is out there somwhere ////
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
