    Need to what is the real value R858


    One R858 is open which is next to U850

    Also every thing work but only if you have two power supplies one 12 volt and one that 4.5 volts then you see it work

      What are the color bands on the resistor?

      For 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 tube
