There is an adjustment that can be done by an authorized tech, this is not something you can do. it is a voltage adjustment that needs to be done . the panel has now come to full conditioning and needs to have changes to the power that drives it. it gets worse because of the higher voltages that are feeding it.

I just replaced bulb with new and after a day there is a dark spot on the screen


I have the same TV - I have a dark spot in the upper left hand corner. I have always thought this TV was dark. Be sure to get OME lamp. Cheaper ones are not worth it and can damage your TV more.
dlplampsource,com--Just a note if this ever happens to you. TV would not come on in the AM-Had no picture, but had sound. It was not the lamp, but the safety switch. It's blue and at the bottom of the lamp housing. As soon as I flipped it and replaced the back cover, the TV came on.

Sounds like your light engine is going bad. I would have it verified by a service tech.

The colours on the screen are very dark and run into each other


This is an older model plasma and could be as simple as a loose cable, make sure you check all inputs, if it does it on all inputs including the ant/cable inputs then it is either a bad signal board or a problem on the Y or X board. if something is loose (bad connection) on one of the boards I usually take the back off and stand the TV back up with the stand rebolted to it. with the TV on and a picture showing gently tap the boards one at a time to see if something is loose. The signal board is in the middle lower section and has the ant screw in on it. the Y is middle left, X middle right when facing the back of the set.
If nothing is loose, there are some adjustments on the Y board that can cause blotches, dots, shading, color distortion. If you want to try adjusting them make sure to mark each ones position with a sharpy. Turn each slightly to see the corrective effect then back till you find the middle spot where the picture looks normal.
