The problem with your TV trinitron wega is at the color adjustment section. It is located at the color board mounted at the back of the picture tube. There are variable resistors that represents the color pattern in the picture tube. Adjust the red color to low level to lower the red color.
Sony sets have several protective circuits that blank the screen if something happens that might damage the picture tube. One of the more common causes is trouble in the vertical output circuit. Given the age of your TV (the XBR models have been around a while), this might also be a symptom of a picture tube starting to fail. Most of these sets have circuitry (called AKB) that adjusts the color drive signals to the picture tube to keep them balanced. If one of the colors is enough out of range the screen will blank. It might be the tube itself, or failure of some part in that AKB circuit. The set might also have defective parts in the input switching or video processing stages.
Unfortunately, I can't suggest any place you might look if you want to try repairing this on your own. This kind of trouble usually needs to be diagnosed and repaired by a professional TV technician who has the service information to track it down.
Hope this has been helpful. Thanks for using Fixya!
A solution I found for our KV-32XBR200 was to press Setup on top of the set, then select the "Demo" item with TV/Video. The text overlay apparently banished PIP. Verified this twice, as I'm at this page because our remote can only turn PIP on :-).
It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.
