1) As with all power supply boards please exercise caution and allow the board 5-10 minutes after disconnecting from power before starting to work on it!
2) When using a substitute for Q406 it will come with scratched identification on the corpus; we do that to prevent competitors (often without repair experience whatsoever) to copy what we come up with after investing time and money in actual repairs.
3) As with all repairs please note that we can never guarantee that this kit is all that is needed to fix the TV. It is offerred based on experience and technical information available to Coppell TV Repair at the time of the listing. For details please see the warranty conditions section below.
