Default Tektronix TDS340, hard to turn on?

Hi, I just bought this tek and while it passes all the selftests,
it's really flaky at startup.
When you press the on/stby button the lights blink once , you can hear
some relays switching and it goes dead.
Then I keep pushing the button and eventually it "catches on"
from then on it operates flawlesly.
Sometimes it takes 3 tries sometimes ~30.
Has anybody seen the simmilar problem (solution would be nice)?
Thanks.




It's old enough for the electrolytic caps ESR to be rising.
Time to re-cap the power supply.Use 105DegF low-ESR caps.
