Sanyo dp50747 Plasma TV fuse replacement and power board check

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

• Caution: Before you remove the motherboard, be cautious of the many capacitors throughout that could cause serious injury. Use a discharge probe to safely rid the capacitors of dangerous charges.
• Wearing electrically insulated gloves and rubber soled shoes while working with and near the capacitors ensures greater safety and protection against electric shock. See iFixit's Project Safety page for additional safety information.
• 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.
Step 3
• That's the one that I found faulty. Just Remove it with a pair of needle-nose pliers and replace with a new one (ft8ah250vp).
Step 4
• TV up and running... and the best part was that it only cost me less than a dollar to get it repaired!!!!
