Its the capacitors on the backlight power supply. Samsung installed crappy ones and they blow up after a year or two. Change out the caps and you're good to go

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.

SOURCE: flicker then display goes black

My samsung syncmaster 225bw when turned on would have the back light stay on for about one second, then go black, with or without the signal cable attached to the computer. After your screen goes black, shine a flash light on the screen to see if you can see any images
I repaired my monitor by replacing several bad electrolitic capacitors on the inverter board. These capacitors had broken bulging leaking vents on ther tops. There were two 820uf 25v and one 330uf 25v electrolitic capacitors that had failed. I ordered from www.digikey.com Panasonic FC series low impedance electrolitic capacitors, However, the 820uf was not curently stocked and had to be backordered, so I got one 1000uf and one 680uf to replace the two 820uf which were in parallel on the board. There were two 680uf 25v on my board which had not yet failed, so I also replaced them. On my monitor, the capacitors can not be longer than 20mm, due to space limitations. These electrolitic capacitors have a life time between 1000 to 5000 hours, so when you order get a few extra of the ones that went bad.

SOURCE: my samsung syncmaster 2232bw wont turn on at all,

Solution for Samsung SyncMaster 2232BWplus:

The problem is bad capacitors: 5 pcs. 820microFarad – 25v and 1 pc. 330microFarad -25v. Replace these capacitors. Then re-solder the two transformers of inverter side. Also re-solder the power transformer and the inductor coil.
To open the casing:
At the bottom of the stand just twist the knob to unlock. Then, use a small flat screw driver beginning from the bottom (left or right) then using a hard credit card (or alike) then slide/glide it in between the cover plastics.

Also damaged capacitors can cause a slow dieing effect to the display, from what I have seen during my research efforts to find solution for repairs to computers people have bought to me. I have only seen "dead" display lcd monitors that have repaired ok by replacing the $1 capacitors.

The set will need to be properly diagnosed to narrow down the problem. You could be looking at a bad inverter, bad CCFL lamp, fault in power supply or main board.

Flashing screen when i first turn on my SamsungSyncMaster 2232 bw


I had a similar problem with my LCD computer screen. I took it apart and noticed a capacitor that was raised up on the flat end and appeared to be leaking a substance. Replaced it with a similar capacitor and works fine, for three years now.

Samsung laptop black screen


Sounds like a loose connection between your mainboard, inverter or LCD. Try to connect an external monitor and see if the display appears to the external monitor. If a display appears on the external monitor, you need a qualified technician to check your laptop. I fixed 3 laptops with that same symptoms, 1 has loose connector, 1 has ground problem and the other is an inverter.

5570z and 2232bw


first, I would check screen cable. try replacing it with a new one, you will be surprised to know how many display problems are are caused by a defected screen cable.
in case this is not the problem, it can get more complicated, but first, just in case, reinstall drivers. its a long shot, but if you get lucky it will save you alot of pain. in case it didn't help, It's probably a bad vertical output chip. if you have some familiarity with monitors and decent soldering skills you could probably fix it yourself, but I would advise looking into taking it to a shop, or at least find an experienced hobbiest if you're not yourself. It's a pretty straightforward fix for someone who knows what they're doing.

Good Luck/Please dont for get to Vote.
