Samsung syncmaster 216BW

[henrysin44]

My syncmaster will turn on for a little bit then flicker then the screen will turn black but the power button will continue to be illuminated. I replaced 1 cap that was blown but it didn't help. Any suggestions?

Re: Samsung syncmaster 216BW

When my syncmaster did that, I just replaced them all. It's a few dollars to do. You save nothing given the time to take it all apart and put it back together.
Search the site, there are several threads on re-capping the 216BW and 226BW's.

Can you define " a little bit" 5 seconds 5 minutes 15 minutes

Re: Samsung syncmaster 216BW

Sometimes it will stay on for a couple hours but mostly like 15 seconds to 10 minutes.

Re: Samsung syncmaster 216BW

I have replaced all of the caps. It will not shut off anymore but every once and a while it will flicker for about 10-30 minutes.

Re: Samsung syncmaster 216BW

First thing is to check your soldering,making sure the joints are good,and you have not made 'bridges' etc to adjoining components.

Re: Samsung syncmaster 216BW

Could be a bad solder joint, bad inverter transformer, or bad lamp/wiring.

Re: Samsung syncmaster 216BW

how would i know if a inverter transformer is bad
also the flickering will get much worse if the brightness is increased

Re: Samsung syncmaster 216BW

Fault on a inverter transformer doesnt come and go. What you can do is
resolder it - remove all the old solder and replace with leaded.


What make /series caps did you use to recap the board?

Sounds to me like it could be the lamps/wiring - when it is flashing can you hear anything
like arcing, Have you nay bulbs in anything you could substitute or another monitor you could try these bulbs with.
If neither how about making up some test lamps

the rest were exact UF and all copasitors are the same voltage or higher.

Re: Samsung syncmaster 216BW

Sounds to me like you have a bad ccfl (lamp), bad wiring, or a faulty inverter transformer. Check out retiredcaps guide on 2 seconds to black. Especially the section that deals with ccfls and inverter transformers and how to test them.
