PVM 27" SONY RED GREEN BLUE issue..

[GuerreFroide]

Hello folks,
I recently picked up a nice PVM from Sony. 50kilos of pleasure WHEN it works.
Sadly, it shows some troubles..

When I power it up, the screen is marvelous. But after some time, it gets worse, the red, green and blue gets far away from each other...


do you have any idea ?

Time based faults on CRT's are usually related to failing capacitors. But failing capacitors usually get better after warming up, not worse. The fact that it can produce a good picture at start suggests that this should be easily to fix, though I am no expert.
