LCD Monitor Troubleshooting - Step-By-Step Checklist to Help You Troubleshoot LCD Monitors

LCD Monitor troubleshooting is real easy for me to do these days. It's a far cry from last year, when I had a slightly tough time figuring out how to troubleshoot and repair LCD monitors.
Prior to that, I did only CRTs repairs which were significantly easier to do. Unfortunately, people stopped sending faulty CRTs to my shop, thus I had no choice but to learn LCD reparation.
You know, thank goodness I found an encyclopedia-like LCD monitor troubleshooting guide online. It has photo instructions and everything so I learned the whole fixing shebang at home.
Yes! There was no need for me to attend one of those pricey LCD repair classes. There's one near my place and the registration cost is $300 for 2 full day lessons! The guide I downloaded from the internet was significantly cheaper and it helped me a lot.
By the way, you can check out the guide via link displayed right at the end of this article. It's a download only so you're going to have to print the pages out and bind them.
Now, if you want to troubleshoot faulty LCD monitors, but you're not ready to get the guide just yet - that's cool. In that case, let me share a step-by-step checklist for troubleshooting basic LCD problems such as no power or no LED indicator.
Checklist 1 - Tools of the trade.
Some of the tools you'll need for a successful LCD monitor troubleshooting are oscilloscope, flyback tester, DMM (digital multi-meter), ESR meter, digital capacitance meter and high voltage probe.
Checklists 2 - Before you take out one of your testing gears - use your eyes first! View each and every one of the components located in the inverter and power section.
Checklist 3 - Take a real good look at the capacitors. If one or more is bulged, then congratulations, you've detected the problem! But this may not be the only problem! Anyhow, you should go ahead and replace the bulged capacitors according to specification.
Checklist 4 - Now I want you inspect the vital components. I'm talking about the power FET, secondary diodes, fuse and primary winding of the SMPS. The last one has to be tested with a flyback tester.
Checklist 5 - If the fuse along with the rest of the vital components turned out alright after testing, then you can turn on the LCD monitor. Since the faulty capacitors have been replaced, you should be able to switch it on without any problems.
