Dear munu007 good morning this is viswanath

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.
Finally change LOT.

With the new flat panels all the rage, you can buy a new and maybe better monitor for next to nothing. Or, as I heard about and then found one, people are leaving perfectly good, functional monitors out on the street for trash pick-up all the time (I assume they have a new flat panel and can't sell a CRT for enough to even bother listing it. I wasn't looking, I was walking my dog, and came across an amazing functional Compac crt monitor! Look around? Repairs are not worth the price

I have a Samsung CRT monitor, every time when I switch it on it constantly changes the colors for atleast 20 min... after that it just works fine. is there any options to service or changing the monitor...


Sounds like the monitor have a "cold joint" or having issues with overheating parts. I believe your monitor was used for long periods of time with no power saving active.

If you are a technician and are planning to fix it, you need to solder all cold joints. Also maybe the filaments inside the CRT are reaching the end of it's life.

If the power cable is detachable, you can check it for continuity with a multimeter.

If you are aware of the hazards of imploding glass, high voltage, and x-rays, you might consider opening the monitor to replace a fuse.

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.
