Same symptoms when I inject a signal from computer vga connector. I've not yet torn too far into it, year of manufacture is 2003. Man, these things go bad fast! Fred MTS Electronics fremur01@xxxxxxxxx Hello there -Dont know your name,but mine shuts down too fast to tell.To answer your question,the flouro tubes age & draw too much current causing shutdown @ convertor ps. So,with that,maybe isolate tubes,scope the waveforms etc.Highest failures I see are the tubes,bad sm electrolytics all over the place[main bd/convertor] FYI Site bylaws dictate you have a sigfile.I didn't even know what that was when I joined.Everyone is pretty helpful here.Regards, Pete "fremur01@xxxxxxxxx" wrote: Pete, I have a similar problem with a DELL 17" LCD in for service. Does this Compaq you're working on also show OSD or self test mode? I wonder if these units develop backlight problems prematurely. My experience is that HP will not sell service literature on their monitors. -----Original Message----- From: techassist-bounce@xxxxxxxxxxxxx [mailto:techassist-bounce@xxxxxxxxxxxxx]On Behalf Of majorthom@xxxxxxxxxxxxx Sent: Saturday, June 04, 2005 4:31 PM To: techassist@xxxxxxxxxxxxx Subject: [TechAssist] Compaq 19" LCD monitor Mod.TFT8000 Comes on then blinks right out.Scoped anodes of the Hi V xfmr drivers and saw great swings but just hash.
