Help: ACER 19" monitor model 7299SL arking in the CRT socket
I have this 19" monitor with this problem;
There is arking in the CRT socket ? I have removed it from the tube and it still arks? I have looked for shorted capacitors but I don't see any? any help appreciated, maybe you have fixed a couple with this problem? |

It is just about anywhere inside the socket. I have removed the red wire
from the flyback and it started arcing elsewhere. This is definetly a problem where the high voltage is way too high. This is obviously a bad design since most monitor go into shutdown if anything happens with high voltage too high? Without a diagram I have ahardtime figuring out where the regulator is. I see an IC around the power supply that is a SLA6046 which I think is involved with the regulation (5 N-channels) I think that somehow it the current load on the high voltage is fed back into that IC. I can't be certain without a diagram. Bad design for sure, "noisette" wrote in message ... Where is it precisely ? "Aslaner" a écrit dans le message de ...
