My monitor is flickering


Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software monitor may flicker and goes into rolling state due to dust, overheating after a long continuous usage,loose circuitry or due to some electromagnetic interference with other like tv , UPS, large speaker systems etc.


FIX :

1.Try Re-installing your Video driver

2 If it is possible, connect a different monitor to the computer. If the flickering disappears, it is a fair indication that the monitor is defective, otherwise go to the next step.

3. Set up the computer and the monitor on a different place in your house. If the flickering disappears now, it is most likely an interference caused by something in the original location. Check for devices which can cause interference.

4. If the flickering persists, check the setup of your system. If available in the setup, make sure that the option Monitor Type is configured as Colour Non-Interlaced.


If you don't think any above possible reasons for the rolling or flickering state of your monitor then we recommend you to get your monitor checked by the monitor company at their respective service cente

Intense white & coloured horizontal line on black background on startup


I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

Disconnect the TV from your sky box and watch TV with just aerial. If this cure the problem, then it is the sky box that may cause the problem. If not then your TV has a problem. Check the colour setting and make sure it is not in saturated mode. Otherwise take it back to the shop.
