Promac LCD-2051 power problem

Promac LCD TV model# LCD-2051 powers up from stand-by, sound comes up and backlight lights up but set goes back to stand-by before picture appears.
Found some bulging 47uF/16V capacitors on power supply board on location C3 and C8. Replacing the capacitors restored normal operation to the set.
