17" PB Parts of screen images appear in color negative

Mirrored displays have different colors. The PB one remains sickly. I tried running the extended hardware test again to see if the ext display would give me a comparison. It doesn't show the test. From what there is to go on the PB appears to have normal colors during the test but I've got no bench mark to judge from. Supposing it is the hardware to the display, what then? It's odd that the desktop image in Hot Corners/ All Windows and Application Windows, while darker as expected, is in true colour.

Oh !@*^ and bother 😟
Purchased in April 2005 in the UK, well out of warranty. I'll try the credit card company. Otherwise I need to look at service costs in the UK. Are there any previous instances of this type of fault? Is it user fixable?

Some other ideas:
A cheap clone part from China
Trade it in for a new Intel machine
Get used to it, wear color correcting glasses!

I called the credit card company to ask about extended warranty ... no way! 'Where did you get that idea' .. 'from someone in America' ...
I called PC World where I bought it. They say they'll call back ... like they may as well have said they'll kiss my ***. Nothing doing.
I called the Apple store, they want £40 ($80) to look at it plus I've got to get it there.
I repaired the disk directory just to be complete.
It's not like its completely broken, it still works, but to put it right it probably needs a new logic board, at least £500
Thats a lot of money to shell out on something only a couple of years old that I paid nearly £2000 for.
Even if it is a portable device this is not a problem that results from shock damage, it's a crap board.
There I've said it now. I finally had to say something bad about a Mac!

Just in case you thought that was the end ... I am pleased to announce that the display problem has just magically righted itself! The screen suddenly became a lot brighter and the colours reverted to normal.
I'm going to call this an intermittent hardware component fault.
Could it be related to an overheating problem. It does get a bit warm sometimes at the back of the keyboard, left side more so. Could there be a build up of dust in the cooling ducts.
Anyway I'm happy for a while at least. I take back what I said about the main board being **

Hi, sorry I haven't been checking the post, I'd kind of given up on the problem. The screen reverted to it's faulty mode, colors bleeding into the white areas, weird greys etc. I'm still wondering if it might be a software problem stemming from one of the 10.4 tiger updates. It starts on boot up just after the cogwheel and the apple come on screen. Any way things have got worse. I've been running with an external monitor and the extra power requirement has blown up my clamshell power adapter. I've rigged up an old PC power supply to feed 24 volts (-12 to +12) and can get by but as soon as I plug in the external monitor small sparks fly around the chassis/ground case on the extension plug and the psu cuts out. I am now worried that continued use of the ext. monitor (which works OK on battery power only) is going to burn out the rest of my power book. I was going to take it to someone, but from where I live in the UK that's a long hike.
In addition to the above trouble shooting tips I've also tried setting up a separate clean user account but that doesn't help. Maybe I'll try a complete reinstall.
How did you get on?

I just wanted to add that if it's the lamp, that's laminated to the lcd for extra slimness, so making the cost of replacement pretty close to buying a new 15" macbook, then I could use the old one for target practice! Or buy a dvd player and a cheap pc for my photos. Some people would commend apple for their method of securing repeat business. It's a throw away piece of state of the art technology which actually depends on extended warranty for it's continued usefulness. Unfortunately I didn't take this on board when I calculated the cost.

I wish I could edit replies after I send them. I don't really mean all those things. Maybe I need to buy a new one anyway. I'm a bit rattled and grumpy about it, that's all.

More to say. Just can't settle. Macs are wonderful. It's an operating system married to dedicated hardware. So far so good. So I moved over from Bill windows to ..... whowever. It doesn't really matter. The consumer seems to be paying for the development. There's no come back is there. I never thought computers were worth jack .... till I got into the Mac. Where do I go next? These guys are getting stupidly rich out of our dreams. And they dare to say they have given benefit to society. Do they really have anybody's interests at heart except their own capital gain? It's about time somebody said get it right or work out a better system. We deserve it after all this faith we've invested.

Please delete these stupid messages I keep sending, they're embarassing 🙂

Oh they're still there!
The solution must lie somewhere and I have got over being cross with it for now. The description of the fault is crucial for the service data base. I'm trying to be scientific about this. I have new information.
When the screen recovers from sleep its colour balance/contrast appears normal for about one second. Then it cycles through its changes into sickly. Although I think the time period is shorter if it hasn't been asleep for very long. I feel convinced that it isn't as serious as feared. If it's software there ought to be a fix. Or could it be the inverter that's overheating?
Is anyone still reading this stuff or is it a non runner?
Regards JohnM

Back again!
There is a wavy raster running along part of the quartz window header which is blue instead of grey. Horizontal lines tend to be continued across the rest of the screen. And vertical lines in the black text appear red, but not always~-)
