Question about Fisher PC-36S90 36" TV
My set was made in 1998. The set had been on for about seven hours. I noticed that the picture was wobbling and then the unit turned off on it's own. I unpluged the set and let it cool down. I pluged it back in and it did not work. I checked the internal fuse with a multi-meter. It tested good. The circuit boards were very dusty. I cleaned them with a soft brush. I saw no obvious burns on the circuit boards.
This TV may turn back on, if you let it set for a few days or week unplugged.Then plug in and see if it will try to start. If that is the case you have one or two bad capacitors. Look for values in this range....160 volts to 250 volts at 1 mf to 4.7Mf. Theses will certainly go bad. And suspect any of those that may be 16volts to 35 volts at 100Mf.You said you have a good fuse, correct? Also check out any bad grounds under the flyback transformer, power resistors and ICs mounted on heatsinks.You may have another fuse, please check again for a second fuse. If the fuse is blown, you have a problem that may cost more than your TV is worth. Remember this TV may have a lot of miles on it! Thanks for asking!
