Samsung T220 Screen Flicker

I have a Samsung T220 monitor for about a year and the screen displays for a few second but goes back to black. When i hold the source button my screen shows but goes to black again. I check my cables to make sure everything is in place but the problem continues.

When the LCD monitor display flickers and or has a black screen then the fault is usually a faulty inverter or the CCFL lamp. When you look at the screen at a sharp angle and you see a dim image then it is a backlight problem and it is caused by a faulty inverter or a CCFL lamp.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

m_r_murphy, The T220 may have developed an internal ac to dc "switch-mode-power-supply / CCFL inverter supply" power problem an you may need to need to have it repaired, Look into warranty or outside technician to refurbish the unit's SMPS/inverter!!! From your description, I believe that the SMPS is in "partial shutdown" mode!!! (no 12 to 14v dc) to power-up the "cold-cathode-fluorescent-lamps" that enable you to see the text and graphics that you already know are being displayed on your lcd panel!!! (+5vdc or 3.3vdc rail still alive!!!) You have "black screen" symptom!!! NOT BLANK n BLACK screen!!! There are lots of DIY videos on YOUTUBE to help you decide if you can attempt a cheap (<$20usd) repair to your unit. Do some reading in my old fixya profile (louie12fix) and visit some of the links you find there. Because your T220 isn't any different than any other brand of CCFL back-lit lcd display in it's basic design and operation you should be able to fix it. Get back to me lmistyrel on aim or do additional comment to this original post here on fixya with info on your next step to repair this unit.
All the other ccfl back-lit lcd monitor tech's on fixya already know what's wrong inside your unit!! Do your research first!! Bye for now, 12fixlouie

Call them as these monitors have a 3-year warranty. No receipt? They will accept your word regarding your purchase. I have two that failed exactly the same way. I called 1-800-SAMSUNG and they gave me the choice of an exchange pair sent directly to my house (requiring a temporary credit card deposit) or by having the exchange pair sent to the UPS store where I would swap out my bad units. No receipt. They merely asked me when I purchased it so they could have it for their records. Manufacture dates such as your (March '06) and a purchase of September '06 are not far fetched at all.

Gateway monitor FPD1975W won't display


Same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.

The start up problem is common and will only get worse. Call Samsung as these monitors have a 3-year warranty. No receipt? They will accept your word regarding your purchase.
