Whats the worse thing that can happen? You blow a $4 part? You already know its bad and its the #1 part that fails.. Install the transistor - 10 minutes work and see if progress is made. --- End quote --- That’s why I usually get multiples of any chip, IC, or transistors I order, if possible. You never know.... --- End quote --- oh yea.. My spare parts are multiplying quickly.. *feels* less painful ordering a bunch of stuff at once and reducing the shipping overall cost. :) |

Better to have a little stockpile to help save time, more than money! |

Sounds like a plan. When the parts come in I'll replace the H/Out, thoroughly inspect the flyback and give it a try. I'll let you as soon as all that is completed. |

Perkin, Last night I disassembled the monitor circuit board from the monitor. Since I’m going to be replacing parts soon, I thought this would be a good time as any to get started. This also gave me a much better view of the flyback and other components. I cleaned up the flyback the best I could and took some pictures of the front and back side. I also noticed some discoloration in the center of the board. Not sure how serious this might be. I also noticed what looks like flyback splatter toward the inside back of the cabinet. Only thing is, I’m not sure if this is an old war injury from a previous problem or if this is the cause of my current problem. I can only speculate as to what might have happened. See all pics below. |
