Question about Mitsubishi WS-55809 55" Rear Projection Television
For several days the colors would jump out of line for a couple minutes and then they would straighten up. After several times of this happening it shut off and now it wont turn on. When you hit the power button to turn it on, it shuts back off before the picture even comes on.
Your tv has two problems showing up at the same time,the convergence IC's have loose conections in some of the conecting pins,the Ic's are mounted on heat sinks and can be identify by the markings on its face STK--- ---,3 letters and 6 numbers,one IC for each color,this pins need to be resoldered as well as any other loose conection or overheated areas in the board. The shutdown problem might be a resistor next to the output transformer,its value should be .47 ohms but it might measure open right now,the resistor is at the back edge of the circuit board on the right witch is the deflection board.If you are familiar with tv service you have a place to start but if you are not too familiar be safe and call for assistance from a servicer.Let Us know how it goes.
