On this article you will get to know the most common problems with TV and their possible diagnosis.RT (cathode-ray tube) television sets have gone down in popularity with the introduction of huge screen, slim and flat LEDs and LCDs. However, there are many consumers who still have their CRT sets and are satisfied with them. But many problems often relate to the image quality, picture color and clarity and sound quality of those CRTs. Sometimes the value of repairing such problems within the CRT TV exceeds the value of replacing it with a replacement TV
No image on the screen
No image may be a quite common problem with beam tube TVs. If you’re facing such issue then check the apparent things first i.e. verify whether your TV is plugged in correctly and is receiving sufficient power for operation. If the facility is OK, then check the video settings (like brightness, sharpness, contrast and movie settings). If the settings are fine then there are often problem within the video cable and hardware. If the essential diagnosis comes out fine then it’d be the time to call knowledgeable TV repair person.
Bowed picture or images not lined up
This is a really common picture problem with CRT TVs. It is usually caused by the failure of an indoor circuit called the convergence circuit. The circuit has convergence ICs, which when go bad create the matter of bowed picture. Sometimes bad or faulty soldered-in fuses and resistors also can cause image distortion. A technician or a professional can easily repair this type of problem in-home.
CRT displays one horizontal line within the center when turned-on
Many time it happens that there appears one thin horizontal line on the CRT TV screen. The evidence of this problem are often a faulty yoke with a defective or burned coil inside it. The other evidence are often loose contact between the yoke and therefore the main board. The third possible cause are often a defective capacitor
Single vertical line in the center of screen
Sometime once you power on your CTR TV you see one thin vertical line on the screen. The evidence of this problem are often a faulty yoke with a defective or burned coil inside it. Other reason can be defective vertical ICs. The ICs may have lost contacts with solder joints because of the heat production during operation
CRT TV crackles when powered up or emits a robust electrical odor
If you’re facing problems with TV not responding to remote inputs, first replace the batteries! If the TV still isn’t responding, there’s a drag with the remote. In this case, it’s better to exchange the remote rather than repairing it.
