Symptoms
TV refusing to turn on or taking time to turn on are the two most popular symptoms of vented capacitors on any LCD/LED TV power board.
Sometimes the power supply may give whining noise when TV is being turned on, but not necessarily.
Visual inspection of capacitors CM851,CM852,CM854 and CM855 near heat sink HS805 is recommended; puffed / swollen capacitors are a great indication for need of change.
Difficulty
If bare board replacement is considered easy then this is intermediate as it requires at least basic soldering skills.
Several components, such as the above mentioned capacitors, will have to be desoldered and replaced with replacements from the kit.
Kit contents
(CM851 and CM852), (CM854 and CM855), CM859, (CM856 and CM858).

Kit tested by Coppell TV Repair:
Yes (with various success; we've see more than one case when this was not the only problem on the board, but we have seen more cases where it was all that was needed).
Notes
1) As with all power boards please exercise caution and allow the board 5-10 minutes after disconnecting from power before starting to work on it!
