![]() I'm new in self-repair. However I will try to keep it short and simple.
Info: Samsung Syncmaster T220 Modelcode: LS22TWHSUV/EN Produced: 2009 Problem: When pressing the power button it takes 3 seconds until a picture appear, then that picture disappear after 2 more seconds. Using a flashlight I can see movement on the monitor so should be a backlight turning off issue. Slogan on the box: "Design That Performs" (..badly because of cheap components) Troubleshooting Done so far:
Now, I'm trying to get my hands on the needed tools. But before I have them I would like to find out precisely what to do. Ok, I tried to read the guide at http://www.badcaps.net/forum/showthread.php?t=10419 While the caps looks fine I guess i will have to check those as well, don't know if I can get hold of a ESR tester or know how to use it. I think i understand the mosfets, there's only one (IC102) and will test that as soon as i get my hands on a multimeter. As far as I understand I set it to 200ohm and check if it below 30. The same with the fuse/picufuse, where it has to be below 1.0ohm. Now the "Bad inverter transformer" troubleshooting is causing me trouble. I don't know what to do. It mentions 4 pins but I seem to have 9 pins on each transformer like this: Any comments on what I should do here? These seem to be the most likely things to test before I go further down the guide. Any other things I should test? Thanks in advance for any comments /Carbonic |
