...PTK195 there is (with back removed and set unplugged) a small circuit board suspended above the main boards to the right as you look from the back. This is (if it is there) the power supply for ...
...PTK195 chassis some dont have the fuse. in that case you will need the convergence power supply board thats what likely blew the 5 Amp fuse. let me know if you need help locating one of those power ...
...PTK195 you can most likely install the updated power supply board. If you can solder and know safety (like discharging caps) you can update the PS chip from an STK730-??? to an STK730-180 (IIRC). I ...
...power supply out and found R14512 colored white from heat. Do you know where I can get schematics or a service manual? I think the resistor is a 10K, 2W. Any way you can help me would be greatly ...
PTK195? THE PTK 195 uses a power supply mounted above the main boards and is about 10 inches wide and 4 inches deep. It is very common on this model for one of the ten diodes to be shorted; confirm it
...PTK195 chassis. There is a separate power supply for the convergence circuits in those sets. The earlier versions used a switching transistor but most sets use the STK730-010 power IC. I have seen ...
