Default Samsung SyncMaster 223BW

Hi all,

Have a little problem with a 223BW samsung ...

Have changed all 5 820uF capacitors,the 330uF,and the big one 100uF/400V (with 150uF/400V)

The problem is the monitor turns off after 2,4,5,10 minutes (no rule when) ...

The power led is on,but no picture,after pressing the power button off/on the monitor works (for 2,3,6,9 minutes) ...







Example : the autoadjust pressed,and after 5-10 sec screen goes off
the autoadjust pressed, and after 30 sec the screen goes off

the power button remains on (blue)


thx

Check with a lamp if the image is still present.
Low the brightness at minimum in order to see if it stays on for more time.

Hello,
As i can see you are using windows 7 and maybe this wont help you but i will say.

I had similiar problem,first i changed inverter transformer because it was turning monitor off after 5 sec, after that monitor was working same as yours 2,4,5,10 minutes.

I have found out that was problem with windows 10 and graphic drivers because i had one monitor and just switched on another.
