Samsung LCD Monitor Repair – How to Fix 3 Very Common Samsung LCD Monitor Problems
Looking for some Samsung LCD monitor repair tips? Well, you're in luck because I have some tips to help you sort out problems such as rainbow display, power shutdown and also the ever annoying display flickering condition.
Now, before you begin the troubleshooting process; make sure you have all the necessary tools ready for use.
Most repairing problems can be solved pretty quickly if you have the right troubleshooting and testing tools at your disposal.
You're going to need these tools: An analog meter with X10 K ohm range, a digital meter, flyback tester, a 35X magnifying glass (to read SMD codes, detect hairline cracks, etc), an oscilloscope, an blue ESR meter (extremely useful) and also a high voltage probe.
Also, try finding a Samsung LCD monitor repair manual that has lots of step-by-step photo instructions. I personally use this one. It contains in-depth repairing strategies for various LCD monitor brands – not limited to only Samsung monitors okay?
Alright, now let's go over some tips for fixing power shutdown, flickering and rainbow display condition…
Condition 1: flickering display
In my experience, this condition is often caused by defective e-caps. So use your ESR meter to test all the e-caps. A defective backlight can also cause this problem so be sure to check your Samsung LCD monitor's backlights.
Condition 2: power shutdown
Upon removing the LCD monitor cover, carefully examine the components located in the primary section. Keep your eyes peeled on the multiple electrolytic capacitors.
If you see any swollen/bulging capacitors, simply remove and replace.You know, I've done many Samsung LCD monitor repair gigs and most problems were due to defective capacitors.
They can' stand the heat. After a while they get swollen and busted so you got to replace them. Another component that you should check is the secondary output diode. When this thing gets shorted, you whole LCD goes off!
Condition 3: rainbow display
Okay, this problem can be caused by a couple of issues. The first is the cable linkup between the LCD panel and main board. So check the cable connection. If it's loose, then that's your problem right there! The second one is poor LCD panel.
If it's the latter, your options are to change the entire LCD panel or you could try reflowing the board.
Listen; don't panic if you're unable to complete your Samsung LCD monitor repair work. With the right photo instructional repair guide, you'll be able to fix all kinds of issues.
