Question about Mag Innovision 19" LCD Flat-Panel Monitor LT916S
My mag lt916 lcd monitor will no power on.There is no led power light so I'm sure its not a display issue. It was working fine while I was online and then it just turned off. I could smell a faint burn odor from the air vents on the top. My real question is how to remove the back so that I can look inside to see if something melted or blew up. I removed the for screws at the bottom but I cant figure it out from there . Please help. Thanks Lupin..
Here is where you can find the replacement capacitors. Although, I am curious to know if the others are holding up NUTZ.... http://www.mcminone.com/search.asp?fkey=25v&restrict=3829501&keyword=470UF

I'm afraid there really isn't much i can say about removing the cover but will say that it sounds like its toast and opening up the back is only going to confirm the fact that you really don't have any idea what's in there...lol...sorry to shoot it straight but I've been there. Start shopping. Good luck

I follow the instructions and replace the capacitors with the same rating. However, the monitor still refuses to display.
I don't have experience in repairing electronics, so i ask my friend who repairs electronics for many years to take a look.
He said one of the inverter transformers is dead. I think he is quite good, since he shows me the oscilloscope waveform of the bad transformer.
Does anyone know where i can buy the inverter transformer?

Just like to say thanks for the capacitor advise. I to had a problem finding a 25V cap so I got the 35, works like a charm.
Trust me I'm NO Electronics techie but this was actually simple thanks to your insight.
And I agree with your comment about the wise crack of the other poster, "Don't knock something till you try it!"

OK PEOPLE I GOT THE SOLUTION TO THE MAG INNOVISION LT916S GOING BLACK AFTER ANY LENGTH OF TIME BEING ON!!! I JUST REPAIRED MINE TODAY! THE PROBLEM IS THE CAPACITOR BANK IN THE POWER SUPPLY PART THERE ARE 6 CAPACITORS I HAD A FEW LEAKY ONES "NOT GOOD" THE CAPACITOR SPECS ARE AS FOLLOWS 470UF 25V 105 DEGREES C MEANING 470 MICRO FARAD/25 VOLTS I HAD A VERY HARD TIME FINDING THE 25 VOLT ONES SO I WENT WITH 470UF/35V 85 DEGREES C THEY MIGHT NOT LAST AS LONG AS THE OTHERS DUE TO THE TEMP RATING HOWEVER, IM THINKING SINCE THEY CAN HANDLE UP TO 35 VOLTS IT SHOULD EVEN OUT AND HEY, ITS WORKING SO FAR SO GOOD!! THE CAPACITORS ARE FROM UNDER A DOLLAR A PIECE TO A COUPLE BUCKS EACH. THE CAPACITORS HAVE A BOLD LINE RUNNING UP ON ONE SIDE INDICATING THE POLARITY. BOLD LINE SIDE IS "-" SIDE WITHOUT BOLD LINE ITS "+" THE POWER SUPPLY BOARD HAS THE POLARITYS STAMPED ON THE BOARD ITSELF UNDER EACH CAPACITOR. EASY 30 MINUTE FIX IF YOU ARE LEARY ABOUT SOILDERING, FIND A FRIEND THAT KNOWS HOW TO. ITS REALLY NOT THAT HARD THOUGH AND YOULL HAVE SOME DECENT ROOM TO WORK WITH. I PROMISE WHEN YOU OPEN IT UP YOU WILL ALMOST CERTAINLY SEE AT LEAST 4 OF THE 6 CAPACITORS BULDGING AT THE TOPS MAYBE EVEN LEAKING BROWNISH STUFF. DO YOURSELF A FAVOR THOUGH AND REPLACE ALL OF THEM WHILE YOUR IN THERE "THE SIX BIGGER ONES ONLY" IF ANY OF YOU NEED FURTHER HELP OR ANY OTHER QUESTIONS ABOUT THIS PROJECT PLEASE FEEL FREE TO EMAIL ME AT [email protected] I DAMN NEAR WENT CRAZY TRYING TO FIND A SOLUTION ON HOW TO FIX THIS THING SINCE I SPENT OVER 300 BUCKS FOR IT NEW. AND IM BY NO MEANS A EXPERT WHEN IT COMES TO THIS STUFF BUT I DO KNOW A FEW THINGS. AS IM SURE MOST OF YOU DO. TAKE CARE YOU ALL AND THANKS TO THE GY WHO MENTIONED SOMETHING ABOUT CAPACITORS BEING BAD IN HIS!
