Hello,
I am having a problem with my monitor. It is a nanao ms9-29a chassis on a toshiba a68kju96x tube. I plugged in a board that had a multi freq output and accidentally switched it to 31khz(doh!!). Now the screen is distorted and wavy at times.
here are pics of the distortion as well as I could adjust to compensate for. The right side is the side that is distorted, particularly in the upper right hand corner..
and
I would just like to know from someone with more experience if they think a cap kit would solve this problem. I am considering the tri rez Dmauro put the instructions up for, but even if I do that I think that if I can fix the original chassis, I would enjoy the challenge and do that as well.
oh thats not good,normally input of 31khz kills the hot but you have what seems to be a sync problem
maybe u550 is damaged
have you lost width as well if so check d502
Thank you very much Grantspain, I was hoping you would respond . I have width control. I will check on u550 when I pull the chasis. Your help is much appreciated.
To give an update to those who were watching. I had no width problems and successfully replaced u550 with a new part. The image looks better, however the problem is still there.
i will have a think on this but for sure something has shorted due to the signal frequency
something like this i never have encountered as i have never put a 31khz into a dual sync chassis
i think it will turn out to be a bloody silly thing in the end
Thanks for all the replies. No there isn't a sync switch on my control board. The problem ocurred after I had switched a board to 31khz. So no adjustments were made, that would cause this problem.
