Question about Projection Televisions
REPLACED BOTH STK'S RED CONVERGENCE STILL OFF. WHAT ELSE COULD BE THE PROBLEM? PLEASE HELP CUZ IM NOT PAYING TO GET THIS 5 YR OLD PANASONIC FIXED.
Next step should be to check the fuse-resistors and low values resistors for open conditions as well the solder joints on them.
These parts are located near the STK ICs.
Also if you can measure the voltage that power up the STK's. If you do not have the schematic diagram, check the ICs data sheet to know where the voltage is getting to the ICs.
You may have to do the convergence adjustment manually after you replaced those parts.
