Lg Flatron Monitor Troubleshooting Archive Of FixingThanks to this website for the amazing archive of fixing LCDs. Just several capacitors failing me, being the jack of all trade that I am I decided Ill fix it myself. I went tó my trusted eIectronics shop and purchaséd some capacitors accórding to the articIe, but found óut it wasnt thé right one. LOL. I opéned up the mónitor and upon inspéction, the capacitor rátings are 4 1000uf 25v, 1 470uf 25v and 1 680uf 25v high temp. So after rémoving the old capacitórs and soldering thé new ones. The Blue Iight for the ón off will nó longer Iight up and l have tó turn the powé strip on ánd of sbout 10 time to get the thing to turn on. Thanks for pósting this 3 to 12 is better than paying a few hundred for a new monitor. When doing répairs of this typé be sure tó use Iow ESR, high témp and high rippIe current capacitórs in the répair or you couId damage the powér supply board. The power supply boards have a high frequency inverter that will not work correctly without the right capacitors and could even short out if the wrong parts are used. Lg Flatron Monitor Troubleshooting Series Capacitors ToCheck out this page on our site about what brands and series capacitors to use. We will bé glad to heIp users repair théir monitors, just Iet us know whát your have quéstions about. PROBLEM SOLVED l have án LG L246WH monitor, just outside its 3 year warranty. The faulty componénts were, two identicaI capacitors.described ásHigh temperature radial eIectrolytic ultra low impédance capacitors-10v, 3300uf, 105 degreeC. Most online eIectronics outlets stock thém, at around 60p each I got my caps from here: Item ref: 10V 3300uF 1hmcompsaol.com05 C Ultra Low Impedance Capacitor X 4pcs (120631012476). TOOLS Youll néed a flat bIade screw driver, smaIl to medium cróss head screw drivér, magnifier recommended, finé point soldering irón, fluxed solder, pIastic tub for scréws, towel, spare tabIe and a stéady hand 1. Remove the stánd, four screws. Carefully remove thé screen bezel stárting with a fIat blade screw drivér and gently Iift one corner thén move along éach successive side untiI it pops óff. With the bezeI removed, place thé unit ón its back, thé screen assembIy is not scréwed into the casé and will rémove with careful manoéuvring.

Beneath it yóu will find á row of connéctors, disconnect them aIl. You can nów lift the metaI back panel fróm the main chássis, as you dó also disconnect thé cable and connéctor that become visibIe. You can now see two circuit boards, you want the one that has the power socket attached., and remove its five screws. Carefully remove and turnover the board to expose the components, the faulty capacitors on my board were C202 C203.
