Samsung LCD TV used to take forever to turn on just clicking

Customer Question

Samsung LCD TV used to take forever to turn on just clicking on and off. Now it clicks once and backlights come on after "jingle" and only white screen. I have checked caps, but none are bulging.

Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems.

Caps have nothing to do with the set clicking before coming on, that is caused by a faulty Mainboard. Even the Samsung tech bulletin stated this, but somehow all over the internet people post about capacitors. Anyhow to fix the TV you need to replace your "Mainboard"- which is the board with the AV jacks on it. It provides the turn on command to the power supply board.

The mainboard for your TV is part number: BN94-01545D , BN97-01870D

It is available used at the link below for just under $50 for your set:
