20 Most Recent Samsung 215TW SyncMaster 21" LCD Monitor Questions & Answers

Have you tried connecting the monitor then powering the PC on. at that point i would say it could be a problem with the PC. When you connect the monitor and power on the PC, do you see anything on the monitor screen at all? Has anything been modified on the PC right before it stopped?

The capacitors BigTech referred to are C110 & C111, 820uf-25V Electrolytic, on the power supply board.

With minor soldering skills, you can replace them with Radio Shack in-store capacitors, Stock # 272-1032, 1000uf-50V Radial Lead Electrolytics for $1.59 each. Works great!

Four bucks and little bit of time saves the monitor.

Flickering or wavy picture is a very common symptom of failing capacitors in the power supply board. This is a very easy repair, it just requires replacing the 6 capacitors on the power supply board. Here is a link to a repair guide for the SyncMaster 214T which uses the same NP-20 power supply board so the repair information will be the same.http://www.ccl-la.com/blog/index.php/samsung-214t-repair/I hope this helps,BuddyMc

Hello,Check for a failure of the capacitors on the power supply board. This is a common problem with these units and its a very easy repair. Here is a link to a repair guide for the SyncMaster 214T which uses the ame power supply board so the repair information would be the same for the 2 units.http://www.ccl-la.com/blog/index.php/samsung-214t-repair/I hope this helps,BuddyMc

Check cable plug, conent it properly

Look for bad caps, very common problem as you can see here:

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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 monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

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

Look for bad caps with domed tops first.
There are more than one versions of the board to get the correct set of caps.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Basic troubleshooting guide here: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors pictures: http://s807.photobucket.com/albums/yy352/budm/ Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.

I have the same problem its defenitly a problem with the lcd monitor not with the graphics card nor the pc. I hooked up the digital and afterwards the vga connection both had the same result. 1 s perfect screen all visible but than black. pushing the on/off or standby button again shortly 1s the display works than it blanks. Did the same test while connected to a dvd player via the composite video... same problem . Since the previous posts are that old and without a solution I guess there is no hope in getting it fixed.

Hello
Yeah, i also faced the same problem i changed all 7 capacitors and the and the LCD monitor was ON aging, i advise the same for you,
Good Luck..

More likely to be bad DC filter caps in the power supply section just like the rest of failed SAMSUNG monitors as shown here.

Hi


Try and change the refresh rate of your monitor by following these options--

1.) Right click on your desktop.
2.) Select Properties.
3.) Click on the Settings tab.
4.) Click on the Advanced button.
5.) Open up the Monitor tab.
6.) Manually increase the Screen Refresh Rate to 75Hz, which is measured in Hertz.

If this doesn't help then check for any electronics item kept near the monitor like speakers, phone,etc. However, if the flickering still doesn't stop then the Internal Flyback Capacitor has gone faulty and you'll need to replace the capacitor. Also, check for the resistor near this capacitor, you may need to replace this as well.

Please post back for any further assistance. If you are satisfied please do accept the solution.

Here is the user manual: http://www.retrevo.com/support/Samsung-215TW-Monitors-manual/id/278ag702/t/2/

Just get an audio cable with mini stereo phone plugs at both ends, attach one end to the PC audio line out jack (Green), the other end just goes to monitor audio line in jack (green).

should be a line in. 3.5mm standard jack to plug in the speakers. Definitely a different plug then the video.
Thank you,
lee

i think this is depend also in your vega card , try to found the latest driver update of your vega card
