Samsung SyncMaster 551 15" CRT Monitor Questions & Answers
My Monitor is blinking in
Hello mrakmed,
Welcome, and thank you for using FixYa!
To answer your question: Your issue is one of three things, that will have to be checked and tested by a professional TV Repair Technician, if you consider this worth fixing.
1. Bad soldier joints around the Flyback Transformer.
2. Bad soldier joints around the 5v low/high power supply Transistors.
3. Some or all of the parts above, could be weak, and need replaced.
Have a great day!

Why does the color white
It is possible that there is a grid voltage problem due to a leak on the capacitor for biasing the grid . So check on the HT section for the capacitor in the grid to the CRT. replace all high voltage capacitors, REDUCE the SCREEN voltage on the LOT(( line output trnasformer)
This must solve the issue.
Thank you using Fixya.

My Sumsang 17 inch monitor
Make sure the video cable is inserted properly at both ends. If it is, try another cable and see if that solves it. If it is hard wired to the monitor, make sure all the pins are in tact.
NOTE: replacement cost for monitor this old is very low so if you need to replace it, it shouldn't be too much.

My monitor displays in red
hi,
There is some dry soldering in the base board of you monitor. Its simple problem but the user cant rectify it. because removing the base board is not much easier. so consult some electronic repairing shop near you. It will not cost a lot. Also check the vga cable of your monitor, if possible remove the connection from the CPU and reconnect it and try one more time.. if you can do the same the i can assist you to do the same. feel free to contact me through fixya.
ok

After the installation of windows
Initially reset the monitor using the reset settings in the monitor and check it.If you were experiencing the problem only after installation of xp only means then it may be a problem related to the video drivers of the operating system or setting display settings to any wrong values .Check the video drivers are up-to-date and setting are default.
If the problem is not solved check the monitor using benchmarking tools and ensure hardware is correct some bench mark tools

About text sharpness
The monitor shouldn't be changing the settings itself unless you changed it. Try changing the brightness and contrast. Otherwise, it might be a video card issue.

Don't worry I can salove UR problem
1.First U can check any physical damage in power supply (220/400v)Main capacitor,
2.And also check LOT It's OK Than Remove H O/p Transister, check SMPS output voltages ,voltages are currect That means SMPS is OK.Check Boosting FET IRF630(Q402)Change it New One,and also change the IC604 7805 Regulator.

Color Problem:
in Monitor CRT Red-Blue-green cathode guns are there.. Mixing of these colour we can get the original colour chrominace technique. if any of the colour gun is faulty we would get more REad or blue or green picture. Measure RGB voltages. you can verfify which gun is faulty. if then check RGB processing circuits. Else there might be problem Chrominance colour decoder system. Contact service centre
