All of a sudden, my t.v. will not turn on, whether attempting to turn it on manually, or by remote. I checked to see that it is plugged in, and all the other hardwares plugged into that particular outlet are functioning properly. It makes no noise when attempting to turn it on, it gives nothing. Just a cold black screen. :( This set is under a year old. I would hope that it has not reached it's end already.
Chances are there is a problem in the power supply ,or other circuit eg:microprocessor,horizontal.i think u should have it check by a qualified technician.its a technical problem and shouid not be taken lightly.
One of the best solution if you are bold enough is to open the case and try to see if the fuse has blown. This is located in the power supply section. Usually you can see this in glass cartridge type. try to see if there is continuity. If none then have it replaced with the correct size, rating and type. However if it proves ok, then the problem might be on the high voltage section which requires someone technical assistance.

This is caused by radio frequency and what i mean by that isyour tv unit is gettng confused with the crystals that control the connection between the tv and remote.The solution to this is to go to wal mart and buy a new universal remote and in the package should be an instruction manual to set the remote to the tv , First find your tv name in the pamplet,second there will show a code of the remote type it in and enjoy.
the problem is in your power supply there are small caps electrolityc capacitor that may be dry if you have esr meter check them and replace is around voltage regulator check for 25mfd at 200 volts or 4.7 mfd ..
