Default Re: JVC tv Power Supply Caps Question

Or you take the view that any cap that under 100uf replace it just because the small diameter caps dry out faster than the bigger ones do

Now if were me and the caps brands that have a tendency to be bad and ones that you replace on site when you see them ( Lelons ) for me this is a brand when I see them I replace them

Most of the time I just recap it and be done with it

But I would not be in a hurry doing this job for the reasons given by Ali in the post above
