Screen going black at random (Radeon)

Post by Njan » Sun Mar 18, 2018 8:53 pm

The symptoms are very similar to those experienced by bobguy10 here.

A little more than a week ago, the screen started simply going black without it actually switching off or the power light blinking as it does when I am AFK for too long. Several people who have no access to the machine, use Nvidia rather than Radeon, and don't run any version of Linux at all on their computers have suggested some quite outlandish things.
More often than not the problem is ‘solved’ by manually switching the monitor off and then on again, or, sometimes, by manually switching the monitor off, waiting for a random period of time, then switching it on again.
When this started I was a couple days away from my scheduled upgrade from LM 17 to 18 and I said ‘well, this must be a driver issue’, so I just waited some time and then upgraded the system. Several days passed after the upgrade without any trouble. (I had already tested 18 from a pendrive and this problem never happened)

Today it's happened again with the new LM 18 and (the horror!) with the USB version LM18.3 as well (as in, just now).

So... is there something wrong with the drivers? Is is a temperature/fan issue, as some have suggested?
Is the graphics card about to die on me?

Any help will be appreciated.

sounds more like a backlight problem with the monitor. Tried another monitor yet? If you do and it doesn't happen with that monitor, then you know the problem is probably the power section in the current monitor. There are videos on youtube on how to repair/replace those parts in a monitor/TV.
All things go better with Mint. Mint julep, mint jelly, mint gum, candy mints, pillow mints, peppermint, chocolate mints, spearmint,....
