Samsung LCD monitor repair and disassembly procedure explained in steps. LCD monitor can be repaired by replacing fused capacitors which are the major cause of faults.
After replacing the faulty capacitor with new ones my Samsung LCD monitor is repaired and working great from 6+ years.
Initially I was facing the issue where in the monitor was not powering up and there was no dialogue box saying check signal. So I thought disassembling and checking out what is wrong with the power circuit might help. This is how I found the reason that is just 3 faulty capacitors. I got new ones for Rs.20(Less than a dollar) dirt cheap. I saved like 1000-2000 INR if I had given the laptop for repairing in Samsung service center. The only hard part is to remember to put back everything in proper place or else there will be a new issue.
This is how LCD monitor repairing was done.

I used this video to help me repair my Samsung SyncMaster 953BW, Very similar. I also had this same problem with my SyncMaster 204B. Crapy caps. Change any swollen caps and any others of the same brand. These caps are junk.

Very helpful, but you didn't show the actual replacement of the capacitors. Do the unplug? unscrew? where do you buy one and how do you know the size? That was the whole reason for me to watch your video. Well done except you missed the climax!

@sayeretmatkaal
@sayeretmatkaal 3 года назад
There are High-Voltage Fluoroscent tubes in this model, not LEDs. First try bypassing the "protection circuit" (search on internet) If you cannot pinpoint the cause of flickering, just convert it to LED (unofficial kits are available)

The repair guy titled the circuit and threw away the metal, the monitor still worked fine for a few days then went back to how it was and after I opened it and fixed the bent the monitor won't display anymore, it turns on but it doesn't display and I have no idea what to do, I used to hit it hard to force to display, now even that won't work.

The inside part of the glass of my LCD monitor shows lot of mottled appearance. How could I open and clean the glass ?. Electronics is OK
@TechnofallKaran
@TechnofallKaran 6 лет назад
You need to check if the lcd and the glass are not like a single combined module. If the problem is only in a few spots then it is better use it without tampering much as it can get worse. Or else it would be better if you can send in some pics of your LCD so that I can help you in a better way. Email me the pics at technofall007@gmail.com
@carlosperesdacosta436
@carlosperesdacosta436 6 лет назад
Namaskar: I went and opened the monitor. In my unit the lcd is separate from the glass. A polarizing film is there stuck to glass. This film has lots of mottling. Trying to find polarizing film or a surplus glass with good polarizer.
