What should I do if the power indicator is blinking on the front of the TV? If the power indicator is blinking on the front of the TV, turn off the TV. Then unplug the power cable from the current power source and try a different electrical outlet. Also, remove the power cable from the rear of the TV and plug it back it in (the power cable tab is inserted correctly when you hear a click).

SOURCE: power light flashed red 4 times then repeats no pic,new bulb/fan!

Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

SOURCE: the power red light keeps flashing six times

The blink code means that something on the board is over current/over voltage. It could be an overload of the +5 line (A/B boards) or the +5 line is shorted.

The TV needs to be opened up and the boards checked. You may be lucky and only need a thermal fuse. Also check your bulb.


I hope this helps.

The TV will not turn on. When the switch at the lower left corner is pressed the light in the switch flashs green for about 4 seconds as the TV seems to go through a start up procedure. Then the light...


The red flashing light is the service code. My guess is the power supply is bad now, but it could be something else. If the TV is under warranty, take it in and get if fixed. If it is not, then you may try to check the power supply first. Count the flashes of the red light and check online for the issues when this model flashes, 4 times or 6 times... or 9 times, etc.

Good luck!
