Left part of the screen becoming dark

Hello,

We own a 27" intel iMac (A1312 model) and since a few months now, the left part of the screen is turning to dark frequently.

This happens several times a day, without any evident cause related to its activity.

Its serial number ends with DHJP .

I just wonder if this might be related to a faulty LED Backlight Board or display cable ?

A picture of the screen can be seen here : http://www.bru.licr.org/~lejeune/images/...

I would appreciate any thought on the subject.

Thanks Dan and aebelcarris for your reply.

Now I've just to decide to replace either the backlight cable or the board, or both …

I'll keep you informed.

Regards,

Jo

Replacing the LCD panel did the job.

Nor the backlight cable nor the board were involved in the troubles we had.

Of course replacing the LCD panel has a high price tag...
