Screen Problems and solutions

If not caused from an obvious break or damage source to the panel, screen failures can come about from five different sources in the machine:

1. The Screen Panel backlight can fail: The screen still shows some form of display, dark and hardly visible.
   
   
2. A small board in the screen panel, called an Inverter can fail: This board supplies power to the panel light, and when faulty will reflect the similar phenomena to a failed panel light.
   
   
3. The screen cables can fail: Movement of the screen or oxidisation over time causes a break in the communication between the motherboard and the screen. Phenomena can be the same as 1 and 2 above, and/or full brightness with no visible image, and/or no sign of any signal or light at all.
   
   
4. The screen itself can fail, totally or partially: Oxidisation and movement over time results in breaks to the interior screen connections. The screen may light up brightly, with no visible image. It may have lines or blocks of missing image.
   
   
5. The onboard video chip can fail: No life in the screen and no result when plugged into external monitor. This is rare.

Some tests on the above problems can be carried out at Home/Office:

• Plugging the machine up to an external monitor which reflects a normal screen display, generally removes item 5 above as a problem source.
  
  
• 1 and 2 above can be determined from switching the machine on, although this test will not determine which of the two is the problem. Further tests are best carried out in a workshop.

All other tests should be carried out by a professional
