    IBM Thinkvision L170P now distorts image intermittently

    Hi
    Shortly before I was concerned because of the CCFLs, but now I have a worse problem

    I can't describe better because the problem lasts a few seconds and I was caught me off guard but the image seems to collapse from the bottom and the upper part of screen shows below, sort of a vertical out of sync, but the image distorts, and also the vertical detail (lines, etc.) became sort of wavy.

    Once this happened while I was playing with the OSD menu, and to my dismay it also distorted the same as the rest of image so I discard the computer's video card as the culprit.

    BTW I am using a DVI cable I don't think that a faulty digital output could distort like this so I also discard the DVI cable (besides the OSD distorting).

    I tried to tap, and hit it gently to confirm bad joints but I can't replicate, the problem occurs and dissapear on its own and happens very rarely, but I am worried this is a death foretold.

    Does anyone have a clue what's happening? In the previous thread (https://www.badcaps.net/forum/showthread.php?t=15461 ) I've altered the inverter but I don't think it could cause that.

    Maybe this could help, but the problems happened shortly after turning on the monitor (10 minutes).

    Many thanks for your help

    PD: thew caps are fine (this monitor seems to be repaired in the past and it'srecapped with lelons (?) ) but all the caps on PSU, and the logic board (uses polymer) look fine

    Happened again, 10 min after turning it on... Indeed, it's like the image is about to roll vertically, including the OSD....

    Sorry I can't post pictures, I don't have a digital camera, only my netbook's webcam and I can't focus properly on the boards..

    Should I recap the PSU anyways? Can this be caused by bad caps? (thought all these Capxons look ok)
    Many thanks
