How to Fix samsung monitor when screen and power led both blinking ?






After the watch full this video, you be able to repair all monitor that any model and any brand, I use capacitor 1000uF 25V. I have to say if any capacitor is spoil is better we exchange with 25V because the voltage for a capacitor is equal 2X energy that section of a circuit. If you don't have the inverter transformer. Better you test after an install new capacitor. If problem solve, monitor is ready if monitor still has the problem , please keep in touch and subscribe my channel for next video. I wish the best for all of you.
 you looking for a special solution  and can not find it, please publish comment on here your question I publish solving the problem on next post, better you also follow the blog.

This different problem power LED blinking and no display. We tray to open screen frame first take out the stand then open the back cover. Second is open all wire (LCD cable, Inverter cables and keyboard cable. Third take out the power board. Now you can see the four capacitors spoiled and around the inverter trans changed color. That means we have the problem of inverter trans need to exchange and two capacitors near to transformer are spoiled because trans gone (this is a solution for no display problem here). And two capacitors near to output cable are spoiled this means 5 V has problem then power led is blinking, we need to exchange capacitor. Better we change all capacitors by 1000uF 25V. Now we will close the back cover and stand. Monitor is okay.
