Question about Samsung DynaFlat TX-P3064W 30" TV

2 Answers

Set will no longer turn on.

Set will not turn on. It is plugged in to known good outlet, but I do not any longer here the normal sound associated with turning the set on. Neither the front button on the set nor the remote will turn the set on. After unplugging the unit for a few minutes, and then plugging it back in, you can hear what I can only describe as some of the low energy part of the start up but not that heavier energy sound that always occurs when I turn the set on.

    I would think that statistically the power supply and board would be dependable enough to not be the issue.

  • jeff_brick Jul 15, 2009

    does the voltage board allow the power supply to be activated?

  • jeff_brick Jul 15, 2009

    What component tells the voltage board to activate the power supply?

  • jeff_brick Jul 15, 2009

    I hear ya, but, again, do you know what component directs the high voltage board to activate the power supply? Is it the on/off button and or the remote control that actually triggers the high voltage board? Thanks in advance, you are most helpful.

    Thank you very much for the insights, I believe this information will be helpful, Best Regards, Jeff B.

This is an older tv. Generally, yes the power supply would not be an issue but possibly it is, any part can fail and the power supply does make a low noise. Probably, the High Voltage board is the issue though and should be tested. I am going to let you know right now that if you want to repair it, it just won't be worth it especially if you aren't electronically inclined since shops will charge $50 just to look at it. A new LCD tv would probably be in your interests, especially with how electronics are always getting cheaper and cheaper.

Tv randomly shuts off. Not sure if it is just overheating or if it is broken.


Hello,
It sounds as if you are having problems with the AC Power reaching the television. Please verify the cord is firmly seated the tv's ac inlet
Also check the wall outlet (and power strip) by plugging in a lamp into it and see if it flickers when the tv shuts off.
Good Luck!

No pic no sound but has power


Welcome to fixya



I have a solution for this

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.



1. Many modern day monitors have an audio cable that goes from the rear side of the monitor to the green colored AUDIO JACK on the back and sometimes front portion of your PC. 2. Ensure to turn up the volume 3. If the speakers are built into the monitor, you may also need to ensure that your monitor is plugged INTO THE PC WITH ANOTHER THICK BLACK OR WHITE CABLE. THIS SAME CABLE WIILL BE ALMOST RECTANGULAR ON ONE END THAT WILL PLUG INTO THE BACK OF THE PC FOR VIDEO AND OFTENTIMES YOUR SOUND.



Solution 3

Lets focus on the external portion of the TV set first (95 percent of all TV problems are related to things EXTERNAL To the tv itself) Check the physical CONNECTION of all cables by removing each wire bare or RCA and reinstalling it (Each power cable as well), once you have removed one cable, check it for fraying, and if it is already bare, splice a new fresh connection for it. 5. Check to make sure there are NO OTHER uneeded radios, system nearby. these systems, when powered on, will cause electromagnetic interference and prevent more than just severe tv interference SURGE PROTECTOR Surge protectors account for more than 75 percent of electric faults to stereo equipment. Lets start with your AC Wall outlet. It is standard in america that 220 Volts from out of these outlets. This implies that each device will be using 220 Volts (From within that grid zone). If anything including an alarm clock is plugged into any AC outlet socket in the vicinity of the stereo equipment/TV, it will cause electric outage, and prevent electronics from even turning on! Your TV needs dedicated electric power. If your TV is located in the living room then unplug everything else in the living room. Lets plug the TV set into a Dedicated socket. Check all light switches to ensure that power is on for that outlet. Check the TV cable for Fraying both on the ac wall end and where it plugs into the TV. Check all GFCI outlets to ensure that all red reset buttons are pushed in, check the circuit breakers for proper connection and they are turned on. Now, lets try the TV set without it connected to any cable services, vcr, dvd, stereo system, etc. Please respond if we have found a solution.

Akai model PT50DL24X/SMS when you turn on the set it makes a popping sound then there is no sound at all. the only way to get it back is to unplug it and let it reset.


the popping sound is generated in the audio output amplifier IC, change out the ic and any associated electrolytic capacitors this should restore normal operation good luck

Sharp TV LC37D40U Aquos malfunction. It fails to turn on (no picture, no sound) except that power button light blinks off and on continuously. Any ideas. Thanks.


The blinking light is a indicator of a internal failure, it usually blinks as an error code, I have two suggestions, unplug the TV from the power outlet and let it set for at least 30 minutes not plugged into the wall outlet, then plug it back in and see if it has returned to factory defaults and returned to normal operation, if that didn't work then contact sharp @ 1-800-237-4277 and they will gladly assist you. Good luck !

Tv won't turn on


Try plugging something else (a lamp?) into the power-outlet, to see if the wall-outlet is providing power.

Try plugging the TV into some other "known-good" wall-outlet.

Take the TV to a repair shop, and have them trouble-shoot.

Lost everything on my laptop as soon as i open it


I dont think you lost everything. Do you see any green power lights and do you hear the normal hard drive and fan sounds when booting up ? If you do and still wont boot up to Windows then reboot and keep tapping on F8 to safe mode and select "last known good configuration". You can also perform system restore.

If you dont hear anything at all, no power and you dont see any green power lights then you may have to plug into another known good power outlet. check that your power connections (including the power adaptor) are secured and if on a strip power off and on. If that doesnt work, try another power adaptor. If those doesnt work
remove the laptop battery and just plug in the adapter.

If youre concern about your personal files you can always take out the hard drive, piggyback it to another hard drive on a known good PC and retrieve the files.

This TV worked very will until the past two weeks when it refused to start up


Any sound? If so, it could be a bad display or high-voltage or associated problem.

No sound and no picture could be a bad line cord, power switch, blown fuse or AC problem.

In this case, make sure it is plugged into the ac outlet and the ac outlet is getting power by plugging in a lamp that is known to work into the outlet. If it does not light, then ther is no ac power at the outlet and you have a bad fuse or tripped circuit breaker (most likely) or (less likely) a faulty outlet or break in the house wiring.

Good luck! :)
