Monitor is mostly green, please help!

[sfetaz]

I have a 29 inch makvision monitor in my DDR Machine.  Recently a cap blew and I had betson repair it.  I put the chassis back in today, and after finally getting things seemingly right, two problems exist.  The first is after a reboot of the machine, the holds are always off, even after fixing them on the last boot.  Second, the screen color is overly green, with no other colors really shining through unless I increase the gains of RBG on the neckboard.  In that case, I see overly red or blue on black colors.  I believe this may be connection problem as opposed to a dial or setting problem because I have tried all the dials and cannot get anything close to correct.  Please help!

Check the transistors in the green color circuit, if not l@@k @ my sig. PM me.

Check the green variable resistor and transistor on the neckboard but try to adjust your brightness/contras/screen first to see where your colors are at. (variable resistors are often damaged during shipping, so take a good look at them). If needed, I can service your machine if you're in the new york city area.

You may want to send it back to Betson for repair.  It sounds like something isn't right.

I am at the point now where the holds don't need readjustment each time but the color is still screwed up.  It sucks cause I need the machine for an event tommorow, Wednesday and for Saturday.  I am in Fort Lee, NJ so if you are in the NYC area help is greatly appriciated and compensated.  My tech and I might be meeting up tonight but he probably won't be able to figure out the cause.

how do you mean mostly green,i doubt they would send back a faulty unit-more likely they tested it on different unit and made many adjustments.if your green drive transistor is short then your screen will be unbelievably green,i doubt you have this more likely their adjustments are different to yours-i am not familiar with your monitor but nearly all i have ever worked on have foreground colours/background colours/contrast/brightness and on the lopti(flyback)focus and screen volts.the neck card is the most likely place for background and foreground pots and just cos you cant see them dont mean their not there.to me your problem is that your background or fore ground green is too high and when you try to comonsate with the other colours you are getting overdriving causing a smudging effect.turn all your colour pots(back/fore)down,turn contrast to min,turn brightness to min,adjust screen volts so you can just make out a picture,bring up your brightness a little,bring up your backgrounds so your colours can just be seen.bring up your foregrounds to give a little depth,bring up your contrast to give richness then adjust your brightness/screen volts and focus to refine picture,you may have to go back and slightly adjust one of your colour pots but this is how i do it,good luck

I brought back the chassis yesterday to betson, and behold, they had the same problem, thinking it might be one of the chips on the board.  Thankfully the repair is warrented so they will fix it and hopefully everything ok.  Unfortunatly the event today had to be changed for one less machine.
