Question about Samsung 2043BWX 20 inch Monitor

1 Answer

Hey Experts! I need assistnace. My Samsung 2043BWX 20" monitor is black (or blank). I do have a flashing blue LED next to the power. When I plug the monitor in a power supple without being connected to the computer I should get screen that says, check power cable but still nothing... Any thoughts or ideas? By the way - the light will blink for 2 - 3 minutes then stop blinking and turn off. (probably a internal power safe option) I want to try and fix this myself without have to wait a "few" weeks for Samsung to fix. Signed - In the dark

Actually, the ultra high voltage 'charger' for the florecence (a.k.a. your back light)has gone Kaput...

If your lucky, someone will have a monitor like yours that has the back light come on, but no picture (should get a similar blinking light situation, but a different code. Like... blink, hold, blink blink, hold, blink). In this situation (if your comfortable doing it) you can swipe the exciter from that monitor and put it in your monitor. Obviously this is a more economical way of repairing the monitor.

Just to be on the safe side (as the repair is blindingly easy. 6 screws, pop out, pop back in) DON'T touch any of the back side components. You WILL shock the supreme **** out of yourself. Between the heavy duty capacitors and the ultra high gain transformers on those things you could jump start a bus. So don't be fooled... those little transformers pack a mean sting.

Hope this helps...

    Thanks... the blink on the indicator is a slow blink....hold... blink...hold...blink... and so on... same pattern. Any idea what the exciter looks like? and thanks for tip ont he power supply - I would hate to go kaput - like the monitor did. LOL

    This thing won't let me post a picture of what the thing may actually look like, but suffice to say, is about 5" square. There will be 6 to 8 small white plugs that orient either on the left or right side (or across the bottom and top, no mixing) and right next to the plugs are the same number transformers. Their almost double the size of a dice (these are the things you want to watch for).

    If I can find a way to add a photo to this clip, I'll post it. I just didn't think to do it earlier...

Sounds like either the inverter board is failing - or it may be the power to the inverter board. Look up your model# on eBay and you may get some insight as well as a source of parts.
