Question about Sony BRAVIA KLV-40U100M 40 in. HD-Ready LCD Television
A plastic/electronic burning smell coming from
vent at top of tv filled the room so i turned off the tv. attempted to
turn on the tv about 30 minutes later but it would not turn on -- no
lights showing either. did attempt to unplug power cord from the wall
but it did not help.
my sony bravia klv40u100m was purchased in january 2007, manufactured in june 2006 (according to back of tv) and has not had any problems at all before this.
It is a real possibility that the power board has failed.
It is fairly easy and safe to remove it and inspect it and the burnt component will be easy to find.
Make sure you place the TV on a flat surface screen down where it is well supported. Do not put anything on the table under the set if there is a chance it will come in contact with the screen. Allowing the weight of the set to rest directly on the screen presents a real risk that the screen will break. Lying flat on a table, the set will rest on the frame around the screen which should be safe.
Do not apply power to the set with the back off as there is a risk of electrocution.
The board is available as a module and can be found on eBay occasionally. The part number is 1-789-496-11 and it will cost between $250 and $300 new.
I suggest you turn the repair over to a qualified service professional for the best outcome. Attempt any repairs at your own risk of creating further damage or replacing the wrong parts. The board failed for a reason. The core cause may not be the power board.
