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 ////

I think you will find the answer is now no place will have them.

Guess I am not the only one with this problem. Seems to be something Dell planned for us consumers to by another tv from them.... NOT!

Check for bad electrolytic caps on power supply, and you can also read the out put voltage to see if it is rifgt, and if so the you probably have a bad invertere, but I would say a bad power supply, and you can go to www.partstore.com to check and see if they carry your power supply.

The unit has a small board at the top of the panel call a t-con board. This is where the data gets transalted to the panel for picture. It most likely isnt available to be changed seperately from the panel. You can try reseating the small ribbon cables on this board. Be very careful! They can be easily damaged. Good Luck!

hi,
You have to check the Audio output IC (integrated circuit) of your tv. If it get faulty then there will be no sound. The audio amplifier IC is on which amplify the audio signal. You can easily find out the Audio output IC, follow the wire from the speakers its other end will go to socket in the audio output section in circuit board. Just trace the track in the circuit board it will end in the audio out put IC. Will be very near to the speaker socket. Normaly the audio output Ic will fitted on an aluminium heatsink. Replace the same with a new one with the same part number. You will get the IC from any electronic spare part shope near to you.

Make sure that you have your internal speakers enabled in your audio settings....

What type of connection are you using for video/audio? HDMI? Have you tried using a standard composite connection for audio?
Thank you,
Lee

If there is a buzzing sound coming from the speakers, when you listen closely the speakers probably went out, you should try connecting external speakers to the tv, if they work you know its the speakers if not, then it may be the TV screen itself, hope this helps.

I have the exact TV with the same concern. I disassembled my set and removed the sound module to verify part numbers. The cheapest one I could find was on eBoob for over $100.00. My solution was to buy an inexpensive sound bar at Radio Shack and install it. Very simple to connect and it sounds fine. I wouldn't suggest putting money into a low quality TV like the Dell, another board may blow out at any time per several techs I talked to.

Need the sound board, and they are hard to find, I once found one on Ebay, and no one at Dell would help. There is a large IC on this board and I couldn't get it. But later heard to check Digit-Key. I had this same set with the same problem.

The set is stuck in "Power On Self Test", aka POST.

Try unplugging the set from the wall for 15 minutes (to allow any stored internal power to bleed down), plug it in and try it again.

Hi,
Please check the sound volume . Or may it was muted.

Hi,
Please check the volume or muted.

When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.

It may be in the shutdown/restart mode due to shorted circuits or failed power supply. That will be the first place to check, please see my guides.
Here are the parts for your TV:

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Basic LCD monitor and TV troubleshooting guide: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors: http://s807.photobucket.com/albums/yy352/budm Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps. Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series. Please post back what you find. Please leave rating if it 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.
