Fried power supply? Possible outlet surge
Hi Everyone, new to the iFixit forums but im seeking some assistance and thought, where else would i go?…
ANSWERS:
"Hi,
Is the TV standby power light on or off when there is power connected to the TV?
If it is off then try replacing the fuse first. If the TV was not turned on at the time there is a fair chance that only the fuse has gone and not other parts of the board. If the TV was turned on at the time then it would be another matter.
Looking online at images of the power board it has a T5A 250V fuse. Ensure that the fuse you get is a 250V 5A Slow blow axial fuse. The T indicates that it is a Timed fuse, the axial type means that it has pigtails so that it can be soldered onto the board
A normal fuse i.e. fast acting having the same rating would blow as soon as the power is connected to the TV due to the initial high inrush current whereas a slow blow fuse is designed to hold until this current has subsided. We’re talking about 10-12mS of time here.
The fuse should cost <$2.00 each from most electronics parts stores whereas online they usually don’t sell in quantities of less than 5 pieces which increases the cost. Just a thought.
If the TV standby power light is on but the TV is not turning on when using either the remote or the TV controls then it may be the power board or possibly the mainboard. Further testing would be required to determine where the problem lies"
