[QUOTE="denyason, post: 1767160, member: 196347"] Dear forum members, I know my late 2009 iMac is old but it does a great job for my needs like web browsing, video streaming etc. Its a 27inch A1312 model. I've done a lot of research online and done most things to try to fix it but to no avail. Its a well known backlight issue all over the internet where the backlight is temperamental and only works on the lowest setting thats if you can get the screen to it work- ctrl+shift+eject helps but its not a fix. I replaced the worn v-sync cable which did nothing. External screen works like normal if that helps. What are my options? new display is around £200-350 which is great but what if this did not fix it? I'm no tech expert but i do have some basic knowledge. I did replace the graphics card few years ago when black boxes kept appearing on the screen and i definitely don't think its the graphics card. Don't want to or can afford to waste a lot of money on a new iMac/pc when mine still looks the part. if i can fix/mend it then it'll last a few more years, it aint dead yet. help would be great, whats your advice? replace the display or is there the option to replace the backlight component etc. [/QUOTE]
