Question about LG Flatron L1710B 17" LCD Monitor
That spread across the screen when a window is open. any suggestions? Thanks in advance!
ITS THE CAPACITORS!!!!!! READ THIS POST IM PUTTING IT UP ON ALL THE OTHER LT916S FORUMS I JUST FIX MINE THAT HAD THE EXACT SAME PROB!!!!!!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 BTLEE26@HOTMAIL 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! when it eventually dies just replace the capacitors! mine was doing the same thing then it finally died. and also please send or call mag and complain this is a ridiculous problem due to crappy business practices.

Try checking the neck board for cold soldered joints. resolder as needed. probably a bad capacitor thou.

I've examined this same problem, and found it's due to worn out electrolyte condensers (the little metal cylinder you can see on the main board). Maybe few of them are at fault, but since the problem is connencted to aging of components, it's convenient to replace them all. Servicing is not simple, because you need identical replacement parts, suitable tools and a certain skill. Best luck.

With a good freind and his good computer swap parts. His monitor on your system, yours on his. After swapping monitors if the problem goes away on yours and appears on his it's in your computer. If your monitor still has errors on the other computer it is your monitor. If the problem goes away on your monitor and appears on his monitor (on your computer) it's your video card or your Mother Board or maybe software. This problem seems most likely to be a hardware problem but I have been wrong before. Reinstalling the OS, Video Drivers, and any Monitor Drivers may also work. If you have built in video support on your motherboard and that's what your useing turn it off and install a new (friends) video card eather PCI or VGA which ever one your computer supports best. You can do the oppsite if you have a video card in your machine and your computer has a built in video support disabled. Remove remove the card and enable the boards video support. If the problem goes away get a new plug in card. If the problem stays minus any plug in cards or with a known good card plugged in it most liklely is mother board related. Hope This Helps

I would first suggest that you verify the video cable and connector are okay. The connector should look like the one in the photo with no missing or bent pins. if you can plug in another monitor, that would help rule out the PC. After that, it would probably need component-level troubleshooting, probably in the video or signal circuits.
