Question about Samsung DynaFlat TX-P3064W 30" TV
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.
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.

Unfortunately - it is probably the power suply in the tv or the board..

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.
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.
