SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

The power/standby indicator is flashing a red light and my tv will not turn on.


Hi,
Flashing of the led light indicates an error code, count how many times it will blink to determine where the fault came from.

On power up I hold the power button down, I can hear some sort of relay kick-on, sometimes a horizontal white line appears across the screen, then it kicks-off, and the red led blinks four times...


Hi,
White line across the screen indicates that tv got vertical deflection failure problem that may be due to vertical output chip failure. If that kind of problem occurred, tv select protection mode and red light starts blinking 4 times.
Please check vertical output chip in tv main board and replace it to solve tv issue. This job needs soldering work so local tv repair shop will help you.
Thanks.
