[PCR-1000] still power on problem

[MN]

hello, i postet this already in the yahoo-prc1k-group,
and try it here again, maybe anybody has a good idea
whats wrong...

hey folks

some weeks ago i asked here because my pcr-1k needs some
minutes to lock onto the right frequency after power-on.

i checked the power supply, changed it against a stabilised
13.8V/6A laboratory-powersupply. without any effect.

the pcr needs still some minutes (from 5 up to 15 or 20) after
switching it on to tune the correct frequency.

some more ideas? i use it in the near of my pc, with a
desktop discone connected with a very short rg-59 cable
(around 0.5 meters).

after the first minutes it works perfect... like i told in the last 
message...

thanks for your help
