I am working on my plasma tv that went black and I am wondering about these High-Voltage Ceramic Capacitors. I have one that I think is bad that has a 102m 400v and another that is a B222k 1kv. I have found a 222k 1kv High-Voltage Ceramic Capacitors will it work instead of the b222k 1kw High-Voltage Ceramic Capacitors? On the 102m 400v can a higher voltage like 1kw be used instead of a 400v. Thank You for the help. Sprinkfitter

Ok, I give up! Where is the Arduino connected?Anyway, unless those capacitors show signs of overheating, like exploding or some other splitting apart, they are ok. What makes you think they are bad?Higher voltage rating for capacitors are almost always acceptable. Just more expensive.Paul

The brown spot on PCB is not bad and is normal for thermistors.Thermistor is always (in this case ) hot on beginning when power is turned ON for a short time then resistance is dropped to almost 0 ohm = current limiter = soft torning ON the electronics.Did you check te capacitors ?Most of the time is problem with the diodes - check 4 of them - those ones between 3 blue capacitors.
