Failure symptoms

The most common failure symptom and the one tha this kit cures is usually manifested by the TV coming on for a few seconds and then shutting itself off.

Over time this can get to not ever showing backlight and directly shutting off.

Unfortunately the same symptoms can be observed from other failures, so we can not guarantee you that this kit will resolve the problem based on symptoms alone.

Visual inspection of the small blue capacitor C26 located on the outer side of one of the two large high voltage transformers may sometimes reveal swelling or even burning, but this is also not always the case.

Measurements with DMM are not guaranteed to help either as the problem may only show itself under load conditions (high voltage and high frequency).

Difficulty level

This is as easy a repair service as they come, but it still requires some basic soldering skills.

You will need an iron - almost any will do, some solder and a Philips screw driver so you can get to the board.
