NEC FE750 17" PC occasional field collapse
Hello all,
Can anyone help me as to how or where to locate a fault in my NEC FE750 monitor (.25mm dot pitch / flat aperture grille tube). Every few hours, (it's done it about 5 times now over the past few days), I get loud "Clunk" sound as if it's just been switched on or off - picture field collapses to a bright horizontal white/magenta line, (pretty sure it's not white), field collapse lasts for just a second then "clunk" again, and Windows desktop appears in the middle of a degauss cycle then it's fine again for hours. This NEC monitor was in storage from new along with several others for years, I've had this one for about a year, tube is like new. Shame to have chuck it for the sake of a disc capacitor ...if that's all that's wrong !! ....any pointers, or referral to a good monitor repair technician appreciated. regards, Richard |
