Convergence is the process by which all three electron beams (R, G, &B) come together and strike at a single spot on the surface of the CRT. Precise convergence is necessary as CRT displays work on the principal of additive coloration. When Red light, Green light, and Blue light are added in equal amounts they will form a white spot or line. The absence of all color makes a black spot or line. Variation of the relative strengths of the R, G, and B electron beams creates color variation. When the individual electron beams (R, G, &B) do not converge perfectly mis-convergence occurs. Mis-convergence can be seen as shadows which appear around text and graphic images. Convergence error can be caused by a Mis-alignment or damaged “shadow mask” of the CRT. Convergence can also be caused due to a defective Deflection Yoke. Since convergence highly depends on the electron beam striking the proper place on the CRT surface, mis-alignment of the Shadow Mask and Deflection Yoke could cause this error.
A wavy distortion pattern caused by the interference between the dot pitch of the CRT and the picture signal. This distortion pattern may vary depending on the pattern, screen amplitude, contrast, brightness, and other characteristics of the input signal
A system where the scanning in a CRT monitor occurs in a sequential or continuous. System using Non – Interlaced scanning contains One Frame and only one Field. By this we are able to produce a clear and crisp Picture. This also reduces flickering Which is observer in systems using interlace scanning. This is also called Progressive Scanning.
When in standby mode, the BIOS reduces power consumption, by spinning down hard disc and reducing power to turn off the monitors that comply with Video Electronics Standard Organization (VERA) and Display Power Management Signaling (DPMS). While in standby mode, the system can still respond to external interrupts, such as those from keyboards and mice, fax / modems or network adaptors. For example any activity from the key board or mouse brings the system out of Standby mode and immediately restores power to the monitor.
A system by which a television decodes an image – a frame is broken into two fields, odd (1, 3, 5, 7.) and even (2, 4, 6, 8.). A television will scan 60 fields per second with 30 odd and 30 even fields created. By combining the two fields every 1/30 of a second, a frame is created thus creating 30 frames per second – a standard in television broadcasting

Check whether the power outlet is working properly by plugging another item into it.
If your PC is in MS – DOS mode, the multimedia button on the keyboard will not work
If the PC beeps repeatedly or if nothing happens when you press any keys, it’s possible that the keyboard is connected improperly. Make sure the keyboard is connected to the keyboard port, not to the mouse port. If you need to reconnect these two cables, turn the computer off, reconnected the cables, and then turn the computer back on.
It’s possible that your system hangs. Then press Ctrl + Alt + Delete keys simultaneously then go to the shut down bar from tab key & press to restart the system which is called as soft booting the system. If that doesn’t work, press and hold the computer “ON” button until the screen is black (approximately five seconds)

Also make sure the power connectors are securely plugged into the Hard disk.
Check the interface cable connection between the hard disk and the motherboard.
Replace 3V battery or motherboard
Verify that the hard Disc drive is producing the noise and not a fan or CD/DVD drive:
Runs Disk Defragmentation – listen to the hard drive. Is the noise louder when Disk Defragmentation is running? If the noise is louder, the hard drive is probably causing the sound.
To verify this, turn off the computer, open the case, and disconnect the hard drive from the power supply.
Turn on the computer and listen for the noise. If the loud noise is gone, the hard drive needs to be examined.
The duration of recording depend upon the number of songs already stored in the player. For 512 MB, the usable memory is 496 MB. If the whole memory is utilized for recording then the duration would be approximately 2 hrs. The no. of songs which could be stored varies from 50-60 depending upon the duration of each song.
For I GB, the usable memory is around 950MB. If the whole memory is utilized for recording then the duration would be approximately 4 hrs. The number of songs which could be stored varies from 100-120 depending upon the duration of each song. The sound quality is undoubtedly good. There is a good inbuilt microphone.
A – The Intex’s MP3 player- 512 MB and 1 GB is not rechargeable. The user could use rechargeable batteries for 512MB and 1GB if desired. The continuous playtime depends on the battery backup which in turn depends upon the usage pattern (frequency) adopted by the user.
