Tip & How-To about Televison & Video
If you can use a screwdriver and have good observation skills you can probably change any board in modern TVs. With the kind of technology we have today the average person cannot repair a board and shops cannot either. The costs for replacement boards are low enough to warrant replacing the board.
There are many places to get the board or boards you need such as http://www.encompass.com or http://www.shopjimmy.com or http://www.tristatemodule.com . First you have to determine which board it is that you need. This can be difficult for even the most seasoned electronic technician.
For example, generally in flat screen TVs the most likely problem, when they will not turn on, is the main board or power supply board. Determining which of the two is the problem is where the experience comes in to play.
If you do not mind paying a restocking fee, and perhaps the shipping on the part, you could order boards until the cows come home and send back the ones you do not need. Generally if you are not a repair shop the restocking fee is 20%.
There are many variables and I would recommend asking the experts on this site to help with the diagnosis of the problem. My tip is only to explain how to remove and replace the board properly.
Once you have diagnosed which board needs replaced you need to order it. Most electronics today are static sensitive and you should not touch the board without being properly grounded. You can purchase the proper equipment at http://www.mcmelectronics.com under electrostatic protection. It should include a mat, a wrist band and the associated interconnecting wires.
Once you have the proper work station you can open up the set by removing all the screws around the perimeter of the back and taking the back cover off.
Locate the board you are changing and remove all the wires and connectors marking them if necessary for proper reinstallation. The most simple way to do this is to use a sharpie and put a unique number on each connector, both the male and female end.
Remove the screws holding the board in and reinstall the new board.
If this was the problem and you replaced the board succesfully you should now have a working set.
