Centipede g07 repair kit installed - no life in monitor

[Peale]

Raise one leg of R908 and meter, it may have gone open. Replace if it has. It's a common ailment on this monitor.

Okay, after long time working on the monitor on and off - there is life. But there is a sync problem. I only have the 6 pin connector connected to the monitor, from the PCB. It seems like there is a 3 pin connector on the monitor chassis too - but what do I connect to this 3 pin connector from the PCB?

I did like Dokert said in post #31 - but just wanted to check that nothing should be connected there.

You don't need to connect the three pin connector, it is for negative sync and Centipede is positive sync.

What is your sync problem?

Ah, the h.freq pot was broken - so now I have a stable picture - but I have to do the curl mod.

Okay, I've done the curl mod and that helped a little bit on the picture - but it still curls a bit in one side and is a bit wavy on the top and bottom.

How does one center the image on a g07? I see there are some pins, but how does it work? The image also does not fill the screen verticaly, looking at the monitor the way it is placed now - any ideas?

you can adjust the horizontal width coil to try to fill the screen vertically; it's listed on the previously posted pictured as "width adjust." make sure when you do it that you carefully use a plastic or otherwise non-metal hex adjustment tool as a metal hex key will heat up like crazy and chances are good it'll crack the HWC core if it's over torqued.

from what i remember from using a K4600 and K4900 in my Centipede, it didn't fill the screen vertically on either anyway.
