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.

This is straight from the service manual (I'm not sure what the problem is but it sounds serious):

When an abnormality has occurred, the protection circuit operate and cuts the power supply. At this time, the defective line can be
identified by the number of flashes (red) of the power led indication at the front of the unit.

Green light flashes 5 and then red light flashes 6

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

is this electricity pocket plugged up to a timer ? or take the tv back to the shop... lost the receit just look for the same tv on computer

check your sleep timer settings thats the most comman prob
