It's winter now. Is the room where the G5 sits cold, like much below normal room temperature? The start up problem could be related to the season.
... can hear the display working...
Your display makes noise? It's not supposed to. That could be another clue. What's it sound like?
Also, those time when the screen doesn't come on, try shining a bright light directly into the screen and see if you can faintly make out that there is an image on the screen. That will inform whether it is the backlight not coming on or the whole monitor not coming on.
Hello and thanks for your reply. Sorry I have left it so long before returning.
Errmm, my room can get cold with the radiator off but I wouldn't call it freezing as there is usually something on in the rest of the house. What evidence is there that temperature would affect the start up of the display? Just wondering that's all.
Regarding the sound of the display. I'll have to restart it again and have a good listen. Maybe it is the actual G5 I am hearing and it is somehow sounding odd when the display doesn't come on. The times when the display comes on normally, everything seems to sound right if you know what I mean. Maybe I can record this on my camera or something and post that for you to watch (don't know if you can upload things to a post).
Regarding the torch or bright light into the screen. I'll give that a go and post back.
Thanks for your help
Many power supplies have a surge suppression device called an MOV. An MOV should be designed to work at low temperature, but if they get cold enough they can prevent the power supply from turning on because they present too much resistance to the incoming voltage.
The flourescent lamps in the backlight can also be affected by being too cold. If they don't light during the brief period that a strike voltage is applied, they will remain off.
I don't know that the issue is related to cold. It's just something to consider. You can see if keeping the room warmer has an effect.
Hello. Thanks for the info. Regarding the display making noise, you're right, it's the G5 (which I have placed right next to it) which is making all the noise at start up. The display is silent.
I suppose it could have something to do with the temperature. In your opinion do you think the fact that it always comes on eventually is an indication that the problem is not too serious? Have you heard of this happening to other G5 users?
I am awaiting someone to give me a torch to shine into the screen.
Thanks very much

I wouldn't necessarily draw that conclusion. If something was working correctly and over time has been drifting towards not working right, you might conclude it will continue to drift that way to the point of no return.
Let's hope not.
Thanks. I tried shining a torch into the screen at start up. I saw no faint images so it would seem that the whole display is not turning on rather than it being a backlight issue.
I wonder if it is something to do with it being a more modern display being used on an old G5? My G5 is a 1.6 GHz (one of the early models). Perhaps if I was running a more recent G5 model the display wouldn't play up? Anyway, who knows? Thanks for your advice.
