PlainBillFor a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.
Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

The only way that I will know for sure what the value of this resister is IF i can get one of these board to work ONE note I do not have any CLF tube that good for these two monitor at this time I do have two other screen that do have good CLF tubes
Like said in the other post I know this board has more problem I may just use this one for parts IF I do this I will cut the inverter board part off the main part of the board and use it to test CLF tube9 PC LCD Monitor
