Introduction

2 year old TV would not power up one day, after doing online research I found out that it could be the a blown internal fuse $.99, or the power board, around $70 on Ebay. Fortunately in my case it was the fuse (ft8ah250vp) that gave up, and after an hour of work, I had it up and running.

What you need

Step 1 Fuse - Power Board

Step 1 - Remove all 42 screws from back cover. Remove top center screw last, it will help to hold the panel in place during removal of other screws.

Step 2

WARNING!!! DO NOT TOUCH ANYTHING INSIDE. Even after disconnected from the power outlet, the capacitors are electrical components capable of storing electrical energy. Some can have the same energy as a defibrillator and could easily stop your heart. WARNED!!!
There are 5 fuses total, make sure to remove them from the holder and check for continuity with a multimeter.
If all test Ok, you might need to have the Power board replaced.
