a) Before I turned the set on, I made sure, that I had already found the optimum settings for all pots besides Vy-, Set_Dn and Set_Up
b) I set Vy-, Set_Dn and Set_Up full counterclockwise
c) I turn the TV on and let itself warm up with a fullscreen movie for about three to four hours
d) I turn the TV off and remove the power cord.
EDIT:dont wait till the tv power light completely turn off and go to the next step quick
e) I removed the LVDS-cable from the Y-Board.
EDIT:disconnect the ribbon cable that runs from the CONTROL BOARD TO THE Y-SUSBOARD just disconnected from the Y SUS BOARD and disconnect the LVDS cable that runs from the CONTROL BOARD to the MAIN BOARD just disconnected from the CONTROL BOARD still dont let the light of the tv completely turn off it have to be quick in order to go to the next step.
f) Turned the TV on again and let it warm up for half an hour.
EDIT:in order to do this step you need to connect the power cord and turn on the tv.
remember that the panel is off but the boards are on let the boards warm.
g) Turned Set_Dn to the exact location I knew it won't result in any noise
h) Turned Set_Up the same amount than before clockwise, but after that went futher clockwise (slowly) until I reached a point, where there were some little clouds of missfired pixels began to arise
i) I turned Vy- some very little amount - the pixelmissfires disappeared
EDIT:dont try this step the panel is off while all the boards are on not sure why he write that.
j) I turned the TV off and removed the power cord again.
k) I connected the LVDS-cable again with the Y-Board.
EDIT:connect the ribbon cable from the Y-SUS BOARD and connect the LVDS cable.
l) Turned the TV back on
EDIT: hope this help better to understand turrican tweak....This tweak also works to reset everything back to normal after you mess with the vs boost lol.just turn the vs pot to original position and go thru the whole process again.
