1.Measure H OUT transistor-----Short.
2.Open transistor.
3.Again measure transistor-------short.
4.Power on----measure EHT supply voltage-----high.
5.Power off-----Add 100W lamp at EHT supply voltage.
6.Power on----measure voltage-----OK
7.Open capacitor C471(682/1600V)------reading-----internally open.
8.Set new transistor MD2103.
9.Set new capacitor 682/ 1600V
10.Then-------

একই সমস্যা হয়েছিল EHT এবং Pf পালটে দিয়েছি। এখন output tr. আর short হচ্ছে না। কিন্তু output tr. খুব গরম হচ্ছে। H.out section এ 160v capasiter 15j diode 400v pf এবং coil টা driver tr. এবং 10/50v capasiter পালটে দেখেছি। কিছু বুঝতে পারছিনা। please help me.

[@CosmicElectronics]

1.Check resister 91k ohm(two pieces)
2.Check KIA431(original).
3.Replace opto-cupler.
