Coppell TV Repair offers you a repair kit for a common problem developed in power supply board YPSU-J013A.
Difficulty: Basic soldering skills are required to apply this kit. You need to have a soldering iron - almost any type will do - and some experience soldering.
Contents: This kit contains 11 electrolytic capacitors. It is always possible your particular board may need more than that, but this is what we have seen common and this is what we offer for the best price/coverage ratio.
Symptoms: Typical symptoms are TV taking time to power on or flat out refusing to power on.
Visual inspection should reveal a number of swollen electrolytic capacitors at the left side of the board (when looking from the back of the TV).
Contents: The kit contains 11 replacement capacitors for the usual offenders.
Notes: Please make sure to let the TV stay disconnected from AC for at least 30 minutes before you start working on the power supply board - there are powerful and highly charged capacitors on it that can hurt you!
