Yes normally clockwise. You will be able to tell anyway if you turn it too low the panel self destructs and cracks with sparks....

Haha just kidding no if you turn it too low the image will go dark and pixelated (pixels cant discharge properly due to not getting enough power) if you turn it too high you will get lots of red, green and blue dots on the screen which is the pixels over discharging.

hmm its only a slight green tinge, its not pixaleted or totaly green that just anyone can see it?

Also there is no limit to what you can turn Vs upto, you can put it at its max and the Tv will be fine image may be too bright and washed out though but won't cause any damage.

This is completely false, running Vs at 220-225V (typically the maximum for these PSUs) will cause damage after some time to the plasma panel, and will increase the power dissipation in the sustain board. The damage to the panel will cause maldischarge or in serious cases may even cause the panel to crack spontaneously.

I would not advise going above 215V.

Generally with the Vs voltage--If the panel doesnt show Any maladies, I tend to set the Vs 2-3V on the low side.

Reasoning being,--just a little less strain on Y-SUS and --who knows, maybe even panel life increase

The D and E series though--seems to Need the full panel sticker value or maybe a little more--depending on condition.
--I dont like these sets much Poor panels and flimsy construction leading to easy crackage.....

Old Q97 can often go 5V below sticker and still be fine--Even at the age they are, Built like a brick crapper!

So am I correct at thinking, that I'm able to swap the e series boards, into my d series?
Im offered the E model at £20 due to smashed screen, they assured me that it was bought Decemeber 2012 and smashed in the Febuary of 2013 which is realy low milage for the age lol.
