Question about Mitsubishi WS-55809 55" Rear Projection Television
My Mitsubishi has a convergence problem as well as video display issue. It powers up fine and shows inputs and channel display on screen. It also has sound. But not getting any diplay video from either inputs and anntena signal. Blue screen shows when you select other inputs such as DVD, DTV etc. Already replaced STK convergence ICS. I as other member was able to get tv signal and raster by removing GENE-CONVERG board. I even swapped GENE CONVERG board from no success. Also convergence is bowed at top and right. When attempting to select Advance Convergence to show ADvance screen Adjustment, It does not come on. When Attempting to adjust convergence it does not move on either ere or blue convergence. . Any assistance is greately appreciated.
Also check resistor values on the chips and resolder the tuner as this can cause problems as they heat up , then replace any electrolitic capacitors in the video circuts selector ic
i will be back to see what you get
