I finally received the replacement LCD from the same source that Mechatrommer mentioned and I took the lCD out of its frame and replaced it without touching the touhscreen
Very easy as nctnico said.
Now the screen looks nice and uniform...I am sure that original LCD should be repairable somehow but I dont know how...
Still running my 3.2GHz Prescott CPU and temps are ok with the original stock fan! But I have got a beefier cooler which I will replace
it. However the CD drive will have to go which is perfectly OK with me.
instead of those Gentle Typhoon Nidec fans (D1225C12B7) which was mentioned in the thread, I found these fans that you can easily buy from mouser : Sanyo Denky 9G1212F101 for the two big ACQ fans and Delta AFB0912H-F00 for the PSU fan
I have not replaced them yet but these fans are easily available and they have better specs both in air flow and static pressure and with the same noise level (or even slightly better) than those Gentle Typhoon fans which was expensive (at least for me with shipping to Canada)
now I am a bit puzzled as to how the fans are disassembled from the unit? There is a foam like layer underneath for noise reduction which is probably degraded after all these years and I am afraid it may be destroyed if I try to lift the fan holder plate. Any hint as to how to safely and cleanly removed the fans and replace them?
