Please help me with the original values of these caps. EC14, EC10, EC9, EC20, EC19, EC18, EC25.
the model number of the board is MLT169B REV. 1.1 2006.05.13[/QUOTE]
Someone worked on this board before and I am not sure the correct values.

Make a list of what caps you have in which positions now.
What problems does the set exhibit.

DO NOT POST THE SAME QUESTION IN MORE THAN ONE THREAD

Decide which one you want to continue with.

someone worked on this power supply and replaced these caps. The set is freezing and I found the 220 uf * 2 caps bad. I want to fix the power supply unit then I can procceed. It seems the 24 volts line is not ok. He replace the 3 front caps with 820 uf 35v.

Yes but what are the board numbers for the caps - cant read them on your picture.
