Default Size of CRT screen keeps changing - loose connection?


"Jon D" schreef in bericht news:9733593903CA171E5D@...
Hi guys. I need some specilist help here.

I am in the UK. The size of the visible part of the screen on my
17inch CRT monitor on my desktop PC keeps changing slightly.


I have had this problem with a Compaq V70 monitor, and only at certain
refresh rates.

The problem was a "broken" resistor (33 kOhm in my case) within the
horizontal deflection circuit, after using cold spray (or air upside down)
the problem was pointing to this one resistor.

Good luck,

Ben - www.pe2bz.nl
