Question about Samsung SyncMaster 971P LCD Monitor

1 Answer

Got a LCD Samsung 971p and when I turn it on it flickers until it either goes black or the image stays fine. But it seems harder and harder for it to start properly. Sometimes it's for over 5 minutes.

Hi i have a 42" LG lcd tv .When i switch it on


the inverter for the backlight likely has a bad capacitor or more. The fluctuating high voltage is causing the jumping and eventual blackness until sufficient charge is on the caps, at which point it stabilizes...it eventually will stay black unless the caps are replaced.

Flickering screen


Hello,

The flickering problem you have is caused by a failing power supply. There are parts called capacitors that are failing and causing the power supply board to put out pulsing voltages until it can stabilize. We have a repair guide posted on our web site at: http://www.ccl-la.com/blog/index.php/samsung-214t-repair/ If you can soldethen you should be able to do the repair yourself. If you don't want to do the repair we offer a repair service for this unit. You can get details for that service here: http://www.ccl-la.com/blog/index.php/service-request-form/

I hope this helps, If so please rate our solution.

Hello Dsidneysis,
It appears that this failure could be in the power supply due to swelling/ bulging capacitors in the power supply.

Sumsung 930b goes dim,and flickers after about 3 min.


This sounds like the inverter has gone bad. If the bulb were bad only, you would see a faint image on the screen with a flashlight.

The problem is on this monitor, it will probably cost about $100 or so to take it to a shop to get it fixed, and that is nearing the cost of a new monitor.

If you are a little bit handy, and can disassemble the monitor, you can replace the inverter. The hardest thing about this, is getting the monitor faceplate open. Just use something firm and softer, such as a nylon spudger (this is something you can find online) or you can carefully use a thin scredriver. You just have to be careful, those cases are really tight.

Here is a good guide for general ideas on how it is done.

I have a Samsung SyncMaster 971P and it flickers while starting up. If you turn it on and off a few times then it will come on with out flickering.


The flicker might be caused by a defective plyback or a cold solder. Have it checked at the nearest service center.
