You have to try to check all the connection inside your system unit, then try to clean it up and check your bios configuration... Try cleaning the memory and also with the power supply,,, Look for an appropriate power supply..

Did you try removing the power for about 10 minutes, then trying again?

do you get any lights or sounds after trying that?

    According to all the other users with that problem it winds up being the power supply.

    If you have a local computer shop you can remove the power supply from the machine, and bring it in. They have a small device that can give you a clear answer if its good or not.

    You could always swap it with another if you happen to have one.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

Hi Daniel,

Please check if you can access the "error code operational check" to narrow down where the fault came from.
How to enter to error code operational check.
Note : The TV must be in shutdown and not have been switched off. When the TV is switched off, the error code automatically resets to 12 (no error).
Press the buttons on the front panel "Input/Device" and "Menu" at the same time and hold it for 5 sec, activate the error code mode. The LED light will flashes denoting a two digit error code.
Example : if the error code is 22, the led will flash two times pause and then flash two times and will repeat the error code for five times.

If you can't access the error code operational check , please let me know the exact pattern of the flashes of the led light and its color. Check if it will continually flashes green to give you the caused of the symptoms and best solution.

Good luck and take care.

Computer will not turn on

Best way to check is to open your case. Near the power supply plug to the motherboard should be a little led light. If it is getting power to the board this light should be green. If it's unlit then most likely your power supply has gone bad. Hope this helps.

Another problem with my 52725

It may very well be a connection issue with one of the wire connections as its not giving you a error code. I would double check the wire plug connections
