My 'almost 5 year old' 20" ACD's exhibiting the above symptoms. In addition, the upper half of the screen is dimmer than the bottom. I've done a lot of searching on the internet and have found that it can be the inverter board and/or the backlights.
At this point it is 'useable' but, according to others, it may not be for long. Have been agonizing over this for a few days now, mainly because I'm not ready to just 'toss' it and add to the proverbial electronic landfill. [Also, don't need a new computer. Love the iMacs but don't want to deal w/ Leopard. Much of the software I have would have to be replaced and I'm not ready to dish out that kind of $$$ when what I have serves me well. Thought about a refurb. but there's no way of knowing what OS has been installed--the 'store' can't/won't tell you...]
My question is this: has anyone dealt with this problem and found the two aforementioned parts at a reasonable cost on line and/or a schematic of the innards of the display so I'd know how many tubes to purchase for someone else to solder in place? Am not comfortable doing that myself and Apple charges $500+ to fix/replace it, almost the cost of a new one. They also do not allow Apple certified service centers to do that repair, at least as warranty work... go figure???!!!
If this is a rerun, I apologize. Tried doing a 'search' and came up empty-handed.
, in advance, for any thoughts/help you can think of!
