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
9 PC LCD Monitor
6 LCD Flat Screen TV
30 Desk Top Switching Power Supply
10 Battery Charger Switching Power Supply for Power Tool
6 18v Lithium Battery Power Boards for Tool Battery Packs
1 XBox 360 Switching Power Supply and M Board
25 Servo Drives 220/460 3 Phase
6 De-soldering Station Switching Power Supply 1 Power Supply
1 Dell Mother Board
15 Computer Power Supply
1 HP Printer Supply & Control Board * lighting finished it *

These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

1 Over Head Crane Current Sensing Board ( VFD Failure Five Years Later )
2 Hem Saw Computer Stack Board

All of these had CAPs POOF
All of the mosfet that are taken out by bad caps
