Can you help me locate the area on the circuit board which is causing an intermittent fault on my CRT monitor. I would welcome some help to work out which part of the circuit board is a candidate to specifically try the next time it happens.
It is a Tatung Mitsubishi V70. Model VM71RDA. (17inch)

HERE ARE THE DETAILS
This fault causes the picture to move vertically. This might happen only once every two days or it may happen maybe four times in a day.
The bottom of the picture will go up by about 1 cm and the top will correspondingly come down by approximately 1 cm.
I notice that the picture at the top and bottom edge is no longer "linear" but appears squashed: I can see the small icons in XP's Quick Launch bar looking all squeezed up.
This effect may not be stable and it may move into and out of this squashed state every half second or so.
I can't help but think that the effect is partly linked to what is on the screen as (I may be hallucinating) there seems to be a co- incidence sometimes between the start of some screen activity and this fault starting.
