Re: Manson NP-9613
There is a connector from the transformer, I opened it, I want to check the condition of the transformer,
4 pins on it, I put one as reference (0) and the other for checking the secondary voltage output, from the result, the transformer is ok .
I checked it with AC voltage on my AVO.
I'm not sure if the relay is good or not, or may be one of the 3 transistors is not good 2x 2N3055 and 1 x TIP 31, I have replaced one of 2N3055 since I checked the hfe of it, it's low. but it doesn't help yet....
Could it be TIP 31 ?
Thanks
