Question about Samsung Syncmaster 940BW LCD Monitor

I need a new inverter board

I carefully took my 940BW apart to find my inverter board was completely fried with burst capacitors and a some burnt chips. Is there anywhere I can purchase a replacement board? Specs are AC in: 100-240 VAC 50-60Hz Outputs: +5.1VDC/2.0A, +13Vdc/0.4A, and 4 channels of 650Vrms/7.5mA

Why does my Samsung DLP tv keep turning off?


are you sitting on the remote under the couch cushion? haha. JK

other wise you have an issue with the motherboard, something burned out on the circuit board. Either take it apart and check the circuits, look for soldier melted down into a flat puddle or anything burnt. Usually a capacitor fried on the board.

Bad backlight inverter on 42" RCA LCD


Does the backllght go out after a few seconds? Could still be a lamp or something else on the inverter boards. You could try used inverter boards from the same set with other problems (broken screen), Or a complete working backlight from another set but very delicate operation to swap the LCD display from one panel to another.

Monitor only lights for a couple of seconds


These monitors have problems with bad capacitors, transistors and inverter boards. This is a common problem with all monitors. If you are comfortable taking the monitor apart, you should inspect the capacitors to see if any are swollen. If they are, you might try replacing them. If you are not comfortable with taking it apart I would recommend taking it to a reputable repair person. If it is capacitors or transistors, the repair could be cheaper than a new monitor. If it is the inverter board, depending on the cost of the inverter board, it mat be cheaper to just get a new monitor.

No screen or sound after removing the covers for the boards. I thought that a connection was loose to the cable connector, so I removed the back covers. I saw that there was nothing I could do, and...


Look again to make sure no cables/plugs are left out.
There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

X9G NAGAIV goes black; can display, but wont.


Took it apart, all the way down to the boards and first examined the capacitors on the power board7d50dd4.jpg. It turns out it was a cracked metallized polyester film cap (C10), not a blown electrolytic capacitor. Ordered a new one and some transitors from DigiKey. Dont know if that is the complete fix, but the cracked cap certainly isnt supposed to be there.

New defrost control fried in same place as old


If the electronics got fried in the same place then you obviously have a fault cauing the board failure. If the compressor relay was burnt out then it would seem to suggest the compressor as a possible cause. If the board is now back to par then I would suggest checking the incoming voltage to the board and when restarting the unit first disconnect the power going down to the compressor from the board. Make sure everything else works OK first. If everything is running I would sugest checking the relay on the compressor body for any damage or burn damage on the compressor windings. If everything looks Ok then I would reconnect the compressor and try again. Personally speaking though I would really encourage you to get a professional to check the system through as you dont want to keep blowing up boards, let someone else do it and be responsible for it. Hope this is of some help.

Resistor on power supply board


Dear Biigjohn, First, first C613 means that it is a capacitor, not a resistor.And It seems to be a electrolytic Capacitor.If it has burst, then it's can will be inside. just search. the details of the Capacitor will be on it. most likely it will be a 10mfd 160V capacitor. Check and replace.
