Question about Samsung 906BW LCD Monitor

Power Supply for Samsung 906BW

The power supply to the 906BW has been intermittent. Sometimes the blue light and screen comes on, but shuts down after several minutes. Supply voltage is o.k., the problem appears to be in the AC/DC converter inside the monitor. Is there a maintenance manual available to help trace the problem and help to disassemble the unit to get at the parts?

SOURCE: Intermittent Power Supply

There is a high resistance short between the pins on the board for the channel/volume/power etc. buttons. This can be verified by ohming between the pins on the board. Clean around the pins to remove the short.

SOURCE: my wife's mom bought us a desk top p.c with this samsung 906bw

Well, seems like the CPU is the source of the problems, not the LCD Monitor.

The simple way to check it is by remove the cable from CPU unit, see for any sign such us color pattern moving or any sign.

the other way is, try using other CPU or Laptop, then connect it to the LCD Monitor.If it works, then you need to repair your CPU.

Hope it's working

SOURCE: what kind of capacitor does a samsung 906bw lcd

There capacitors would most likely be electrolytic type. They are polarized capacitors and used for filtering DC voltage supply to remove the ripply and smooth the DC power.
If you cannot get a 10 volt capacitor then you can use a higher voltage type provided it can fit on the circuit board.

Samsung TV shutting off by itself and relays clicking


If you don't know what you're doing, don't open it up to fix it!
There are HAZARDOUS voltages on the power supply board EVEN WITH THE TV UNPLUGGED!!! The capacitors can hold a charge for several weeks!

Clicking noise can be coming from bad capacitors on the power supply board.



It's usually easier to just replace the power supply board.

I have a element model #ELCHW402 42"screen it cut off and when u turn it on blue light comes on the element logo comes up very dimmed looking and popping in speakers then shut off


Hi Cecil
Cant see anything in photo

Sounds like Power Supply is faulty or senses a heavy load (current) and shuts itself down.
Popping probably is poor voltage regulation from power supply

Open it up and check power supply capacitors
Or

Samsung 906BW failure. Screen is black; Power indicator blue and flashing. Worked fine the day before, Alt monitor works on same desktop (Win Vista Home Premium on Gateway DX4200-09/AMD Phenom 9150e...


Try it on another PC first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, 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
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Samsung 906BW monitor wont turn on, power switch


rommelnmariv, 906BW will need to use warranty or if you are not a tech with soldering equiptment then unit will need to visit a tech to be evaluated for it's Black screen or It's Blank n Black screen problem. Read my older fixya responses (late 2009) and follow all links. Yes, some of these can be fixed-up (DIY) for under $10. Read my fixya profile for about an hour !!! Maybe you will ask your 906BW " What Brand of capacitors do you have inside you??" Bye for now. 12fixlouie

Power supply will intermittantly not turn on when start button is depressed. After a period of time, it will start. Ten or 20 minute wait period insufficient. Sometimes successfull after several hours. No...


This could be one of two issues: Your motherboard may be set to shut down when your CPU reaches a low temperature, which can be fixed by getting into your computers' BIOS settings...Or replace your power supply.

Two things in the problem one would be with the power supply unit another would be due to pins bent on the cable itself check those and make sure that is not the case.
