You are very right! Something that I overlooked! Shall be more careful next time! Many, many thanks for your keen observation!

In such a large scale repair,if I were in your shoes, I would have replaced that fuse as well. I have bitter experience about this issue. Many times, when repairing similar large scale failures, I performed catastrophic tests on the fuse itself just because it had survived. I can assure you dear Parasuraman that all surprisingly they were no fuses at all in the sense we use the term! They opened far beyond their rated current offering no protection at all as they should supposedly do!

Well, if you find the capacitor is dark, rather symptoms of heating up, better to replace it. I would not recommend 'touching', unless it is in secondary, low voltage area! Please use a temperature probe of the Digital Multimeter to check whether the cap is getting heated up! If you have an analogue multimeter, remove the suspected capacitor, select a very high ohms range and check the cap. You should not get any reading. Sometimes the needle will kick to right and go back to left, which is an indication of good cap. Though it is advisable to have a capacitance meter as these are nowadays available at cheaper rates, it is not a fool-proof test, as the cap might breakdown at voltage built-up. For that, you may need high voltage capacitor tester, which is a costly instrument! (Breakdown tester)

is there any way to figure out wether a ceramic capacitor is bad or good on visual inspection
or by touching it ?

thank you
