This info is from a set of notes by Phil Frakes. I have condensed and re-written them to save the important points. I know there are a number of you who can make use of 'dead' 318 monitors. At the end I have also attached a not about reconditioned TAXAN monitors. George THIS INFO POSTED SEPARATELY FROM INTERNAL AT&T NEWSGROUPS, KEEP IT THAT WAY please.... Taken from the hotline bbs [1-201-769-5616] Subj: CRT 318 H Phil Frakes 02-05-89 ================== Many of you have heard that the 318H monitors are not repairable. Tan't so! This note details the symptoms of a common problem (at least the symptoms are) with 318H monitors. [the monitor is made by Hitachi] It is VERY similar in nature to a problem Mac's have, I believe we are on the right track. When the flyback transformer goes, apparently the power supply senses the overload and shuts down after a few seconds. [Lots of folks have told me they thought the power supply was at fault but could not find a diagram to fix it.] If you can keep the power supply running, you will find the horizontal output transistor will get very hot very fast. [That, btw is only for the experienced few, PLEASE DON'T JUST TRY IT!!!] Replacing the flyback fixed the monitor. After Phil saw a second monitor with the same problem, he knew it was going to become a common one. If you are the type that would want to change that part yourself, you can get a flyback from: Integrated Systems Service PO Box 713 Lafayette, NJ 07848 [Phil got his parts here I am sure we might be able to find out more sources if we acn get a little help] Phil said they were $88 +shipping. A service manual was also available. TAXAN NOTE From: JEFF JOHNSON Subj: EGA ON 6300 For anybodys info, I called Taxan and found that you can get many of their discontinued monitors from them as refurbished models. I just got a 650 for $280 and it will handle EGA just fine ( but not VGA ). They also had 630's, and 640's and the special cable for the 6300. I don't have their phone number right now but any dealer should be able to give it to you. -- George Wilkin AT&T Network Systems,(IH MAIN BL) 2000 N. Naperville Rd.
