Monitor fails during use

Hi,\015\012From your description/post, it would seem that something is overheating in your monitor. It is possible to be a cold solder joint or a component starting to fail. Since this involves component level repair, use of a VOM and a soldering iron, it sort of limits a do-it-yourself repair not unless you are comfortable working in such an environment and with such tools and equipment. A sure sign of cold solder though is if when it is jarred it turns itself on. The "growing darker" possibly indicates backlight fading.\015\012You may need the services of a qualified professional to have this repaired. Good luck and kind regards.\015\012Pls post again should you need further information.

Motherboard failure Hi I have been told that my motherboard in my Compaq Presario , which is 2 .5 yrs old and has not been used for 1 year , has failed. Can someone please tell me how a motherboard can fail. I bought a new monitor and plugged it into the PC and I got "No Signal" on the screen for a few seconds before it went blank. The monitor is OK on my other PC. I have been quoted 400 AUD / 600 USD for a new motherboard. Is this a reasonable cost? Thanks
