1 , the entire screen in just machines reddish (some with color display will retrace lines ) , but the blink of an eye to normal ;

2 , in use, the screen occasionally redness , but also on the normal blink of an eye ;

3, the entire screen was white and with a heavy red line and immediately retrace protective shutdown ( or black and can no longer boot up ) .

 

Understand the point of failure errors:

 

For a lot of people say that this type of failure is the graphics card has a hardware failure , it was also said CRT scrapped , others say that the graphics driver damage caused by these types of views are wrong.

 

Cause and Countermeasures :

 

Indeed, this very touching picture tube failure will cause the failure phenomenon , but it is not beyond repair - a slight shock available , serious supply filament winding rewinding , and sometimes a color video amplifier electron gun power resistors Weld or in the form of damage or breakage resistance increases will cause such symptoms. In addition , there are some models just have some minor leakage between poles , usually no maintenance, but there are moments when you boot cast, a few seconds of normal ( the first one kind of failure phenomenon ) .

 

For touch -pole ( sometimes only leakage ) fault that you can give a professional service personnel , which is characterized usually cause a protective shutdown.

 

For non- regular cast failure is usually related to the electron gun as long as the video amplifier and peripheral components resistance welding power supply what can be done.

 

 

For the power supply circuit damage resistance was caused by the failure phenomenon and the same as full screen touch pole line and a sweep back very bright colors , but it does not result in a protective shutdown , the solution is simple - the new resistance for the same resistance You can ! Of course , if the resistance is bigger, should be treated ones .
