Screen brightness control not working and screen unusably dim

A couple of days ago, while using the (original) phone, the screen abruptly dimmed, and won't brighten up even in manual brightness mode. Initially the back-light flickered a bit between different brightnesses, but I can't really notice that any more. Now the only exception to dim screen is when the phone has been sleeping for some time and is awakened, the screen brightness is sometimes normal for a fraction of a second.
I think all signs point to a hardware issue, which is why I would like to know if anyone else has had similar problems; or problem with the display in general and knows whether these kind of issues are fixable with reasonable difficulty and cost.
You can try opening CSD tool (enter ##310## in the dialer), there's a test in there which raises and lowers the brightness so you can be sure if it's a hardware issue or not.
