pentranic chassis failure
« on: June 07, 2022, 06:13:21 pm »
Hello everyone, I need your help.

 I've got :
 Chassis: Pentranic CH-288
 Display: Pentranic A68PNT18X

 My chassis makes a sound (click-click)
 I changed all the electronic capacitors, the ic2-ic3 and something else as recommended in multiple publications and the failure continues

 Today I unmolded the hot collector (q401) and placed a lamp on +b, the "click-click" stopped and I was able to measure that the voltage of +b= 130v. With this I rule out that the problem is the source, now I don't know with which tests to continue , or perhaps to change .

me thinks if you disconnect Q401 and it no longer clicks, that Q401 is needing to be replaced.
