Pentranic CH-288
« on: November 11, 2018, 05:39:22 am »
I have a 33" Pentranic CH-288 that has a very dull image.

The B+ is at 108v so right on spec but the video B+ is 140v instead of around 180v and the 18v line is very low also.

Any pointer as to where I should be looking?

When I crank the V adjust pot to max the picture looks alright, Video B+ is around 177v but B+ is 144!
 Didnt want to blow something so i put it back to 108.
