Samsung Syncmaster 215TW in analog mode comes on for 1 second displaying whatever is currently on desktop and then goes black. Recycle power and get same result. Other modes seem to work. I have tried it on many computers with XP or Win98. Same result. Suggestions?

Additional observations: It appears that any time computer transitions from desktop to screensaver or back to desktop, the screen comes on for around 1 second, then black.

I was unable to see icons when applying a bright light close to lcd.

Try a different cord if possible, if not, trash the monitor. I'm not one for giving up, but that's really the only option I see here.

Just tested S-Video in and it works. No black-out. So...I think question becomes what functions/circuits are on analog port that are not on S-Video that could cause momentary on any time you switch monitor in analog mode?

Every article I read seems to point to failed inverter or lamps, but I can't ignore the fact that the unit works fine in S-Video, etc. I don't want to tear the hardware apart for a setting problem.

No luck so far. I'm really surprised at the lack of response. Thought this one would be interesting to lots of folks.

You shouldn't be too surprised about the lack of responses, this is an electronic failure of some sort and without schematics and specialized testing equipment you won't find any detailed answers. Most techs do not repair monitors, just isn't worth the time or cost.

However Samsung does have a 3 year warranty on most of their monitors.

Normally I think the same thing when a monitor has no video or scrambled video its best to pitch it but in this case the video portion of the monitor appears to be working but screen display is cut off as if some power management function had timed out. I keep thinking there may be some setting I haven't found or a fairly simple timer circuit causing the problem. Remember I can use the unit in all modes except analog and it works fine.

I have a Syncmaster 204B that did the same thing. I got it repaired under Samsungs 3 year warranty, and they paid shipping both ways.

I'm pretty convinced that the problem is either in the front end hardware for the analog port or in a setting for that same input. I'm ready to troubleshoot the analog input, but would like to have a schematic or service manual. Can anybody suggest how to acquire such information?
