macbook screen goes black several minutes into streaming, F2 brings display back

I Have a (2007?) black macbook. 2 Ghz Intel Core 2 Duo with 3 GB 667 Mhz DDR2 SDRAM running OS X Lion 10.7.5.

It's mainly used as a mirror display for streaming. Most recently, after several kernel panic messages that required constant shut down and restarts [after receiving black screen with multiple languages saying "required shut down of computer / power off"], I erased macbook and rebooted all OS X; from disk Tiger, to disk Snow Leopard, to Lion download. No peripheral programs being used.

I've reconnected several cords, adapters, etc. Cleaned computer. Also, employ cooling pad with fans while in use to keep temperature down.

While streaming Netflix, and occasionally other sites, macbook display shuts off and goes black unprompted while streaming. F2 will bring display back to life. Screen saver is off and set to Never.

What am I missing? Anyone have a fix on this?

MacBook, Mac OS X (10.7.5)

I am guessing the Screen Saver setting did not "take", Try this:

Thanks. Sadly, PRAM reset did NOT help. After 10 minutes, streaming stopped again and screen went black. F2 brought it back up. Suggestions?

Does the screen go black when the computer is idle, or only when streaming?

Have you run Disk Warrior and/or TechTool Pro. The former is excellent at file and directory repairs, the later is most useful for hardware diagnosis, including hard drive surface scans.

Only blacks out while streaming.

Sorry, I'm out of ideas. Let's hope one of uber-gurus will see the thread and offer a solution.

Restart your computer while holding the D key before the grey start up screen appears, it should start to the Apple Hardware Test. If for some reason it doesn't insert the original install disc that says it contains the hardware test. Since your original system was Tiger it may be on disc 2. Anyway insert the proper disc and start up while holding the option key, that'll bring up the boot panel from where you can select and run the hardware test. Run it in extended mode for awhile. I suspect that there may be a hardware problem due to the kernel panics you were having.
