Question about Samsung 913B 19 inch LCD Monitor

1 Answer

Samsung 931B monitor (doesn't turn on)

I'm a high school student who was asked to fix a dud monitor. This monitor is the 19-inch LCD 'Samsung 913B [R] A' model (the model code is LS19MEBSBD/XAA). I have taken it apart and re-soldered the ground on the power supply. The power button lights up but the screen does not even flicker. I looked at the boards and nothing seems to be out of place and there are no scorch marks. I took it apart again today and checked the ports that I reconnected wires to, and nothing looks to be out of place. The monitor is not of great value to the school but it would be fantastically awesome if I were able to fix this and put it back in working order. Thanks everyone for all your help.

    Thanks. Very helpful. I identified four blown capacitors and my teacher is ordering them now. I will solder them in in two weeks. Thanks for the help! -Chris

Check for blown capacitors on the power supply board, this is a very common problem with LCD monitors. Here is a link to a web article showing what to look for. The second link is to a source for capacitor repair kits for that series monitor.

SOURCE: screen goes blank after 2 seconds

Do you have the video set to a range that this display cannot handle? Try rebooting into Safe Mode and set the resolution down to 800x600 or 1024x768 and see if it that will get you back. If so, then look up the specs of the display and set it no higher than it's max.

If it physicaly powers OFF, then you probably have a power issue.

Hello cstafford35,

Your monitor has a very common problem. The internal power supply has blown a part called a capacitor. If you are comfortable working with electronics and with soldering I can talk you thru the diag/repair. If you are not ready to tackle that we also offer a repair service, about $30 plus shipping for your model. Let me know if you want to try fixing it yourself and we can go from there. The repair will require opening the monitor case and replacing from 2 - 5 parts. You can call me at 318-447-9040 if you have questions.

savato321, Most black screen lcd monitor owners don't have the smarts to open up their monitors to do a VISUAL inspection of the "switch-mode-power-supply/inverter supply!!!! You're good. Now you will need to know some stuff about electrolytic filter capacitors! First, the "uf" or "UF" means micro-farad! It is just a rating given to express the storage capacity of the device. Next is the voltage rating. A 16v rating means that the capacitor should never be placed in a circuit where the voltage will exceed 10 to 12 volts DC. Your 820 uf cap rated at 25volts will most likely be in a 12 to 18volt dc circuit. Now for temperature rating. All caps have a maximum temp rating. Most clock radios, stereos, will use 85 degree centegrade rated caps. Printers,PCs,monitors, will use 105 degree C rated capacitors. Never replace with lower specification units! You can GO up but never DOWN. If 1000uf 25v is all you can get it's OK. If you can get 820uf 35v units and they are not too big and they will fit on the board sure you can use them. I would stick with the OEM design voltage rating. Electrolytic CAPS are polarized!! You must replace them + to + and - to -!!! If you screw -up they will blow-up!! The wire lead closest to the printed STRIPE on the cap will be the negative and the unmarked terminal will be the positive. If you visit www.ccl-la.com/badcaps.htm you will get more info on recapping your SMPS. You can also watch some DIY videos at YOUTUBE for "lcd monitor repair" that might be helpful. Also visually inspect the SMPS/inverter printed circuit board for "COLD" FROSTY looking solder joints. They should all have near mirror finish to them. Let us know the name of the BAD CAPS you remove from your unit. You may even want to document with pics with a digital camera what you find. Well, good luck guy. 12fixlouie

The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once inside there will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol! The other screen/monitor blinking(surging) is prob caused by the other monitors faillure and should stop when you replace/fix the broken monitor.

Samsung 19 inch lcd monitor turns on and right back off


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
