CTC 203

Is it shorted Collector to Emitter? Then it is bad. If you read around 40 ohms base to emitter, it is good. Look up the datasheet for any horizontal output transistor and look at the internal B-E resistor.

Might want to brush up on electronics and consumer electronics repair, i.e. TV sets.

Michele Smith: Make certain that you test the transistor "out of circuit" to obtain conclusive results. The HDrive transistor is usually a "standard" NPN TO-92 silicon so the testing is usually straight forward, whereas the HOT usually has an internal resistor and damper diode which will complicate the test results and cause confusion unless you know what to look for in your meter readings. Shorted transistors can be the result of faults in the surrounding circuitry.... or.... it could have just been the time for the transistor to fail without any other related circuitry failures. Old fashioned troubleshooting, testing and experience will speed the diagnostic process. You might want to go to the website for this newsgroup at
