Samsung 940mw - no power. Have read many similar issues - it used to blink (green) and require many "pushes" of power button to finally start, but now it won't do anything. Help...

Hello,

That is a hell know problem with the 940MW tv/monitors. The power supply has failed because of parts called capacitors have shorted. If you can solder then you should be able to repair your monitor. Here is a link to the repair guide for this issue.

brinz97, Yes, to your ?.. Do this first!! Turn it off and subin a working monitor. Place 940MW in safe place! Now check to see if it is still covered by Samsung warranty. The next thing for you to investigate will be YOUTUBE!! If you haven't been there yet, you sure are missing a ton of stuff on typical repairs of lcd monitors!!! Only you can make the decision to spend $12 and fix it yourself or $40-$100 to contract out the work! A very good clue was when you stated "great picture...when it comes on" !! This leads me to believe that a simple repair to the "switch-mode-power-supply" is all that is needed. It could be as easy as resoldering 1 "frosty/cold" solder joint or replacing 4 to 6 "electrolytic filter capacitors" that have failed prematurely!! To view some of these goto www.ccl-la.com/badcaps.htm or any of the sites that deal with BAD capacitors. Here is the advice you need. I say "If you are able to effect a repair for less than $15, then also think about getting a new one also with the $ saved!!! Then you will also have a working SPARE unit on-hand. If you need more help get back here to fixya with another post to your original. or [email protected] I'm 12fixlouie

kirstin_lewi, It is fixable, but you should check with Samsung first! Is it covered by warranty? If not, can they provide you a REFURBISHED unit under a SWAPOUT+$ type program? Is your unit <3yrs old? Some units which exhibit your symptom of failure can be fixed for $30-$70. I would visit youtube and view some video clips (the longer ones) >8min length to see what is involved with doing a repair of a typical LCD display. Search under "LCD REPAIR" or "LCD Disassembly" or something similar. Also query for "bad capacitors", "swollen capacitors", and last but not least "failed inverter circuits" which are the things that provide the 800 to 1000volts needed to light-up your CCFT lamps. I hope that this information was helpful to you. Please rate this response with fixya if you can. I'm louie12fix on fixya or lmistyrel@aol
Bye for now.
