Hi Paul,
Thank you for your helpful reply. I followed Peter and your advice and
have established, (with the aid of a torch and viewing screen at an
angle), that there is an image present on the laptop. I will try to
google the make, model and fault to see if there might be any
suggestions on the likely cause - do you know if laptops have separate
power boards as do desktops? if so, that might be a likely starting
point. I agree with you Paul, nothing lost in trying to repair something
thats already broken!
Thanks again for taking the time to help.
Regards,
John.

My tech group scrapped it, although a google search showed the model was known for this and parts were inexpensive and readily available.  My attitude is I try to fix most anything, it's already broken, is it worth $20 or so to try to fix it, if it's otherwise working ok for you?  I wouldn't spend significant dollars on labor.  Many components simply unplug/unsnap after removal of some screws..

The parts needed to repair such are not too expensive, but unless you can do it yourself, the labor will put a dent in your wallet. To tell if the display is bad or the backlight is dimming, try to look at the display at an angle when it appears to be off. You should still see the display but VERY dim if the LCD is ok.

> We have a Packard Bell laptop model PAWF7, its running win 7 and the display started intermittently going off, sometimes hitting the brightness button repeatedly would bring the picture back temporarily. I have tried using a pc lead to connect the laptop video to my television and everything works perfectly via the tv screen. Would anyone on the list have any suggestions what I could try to eliminate possible problem areas.
