47in Phillips-tv picture goes black still has


Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the case..you have the above problem!

Screen goes black after 30 mins of working.


There are a few things you need to check here.
1. It could be that your computer power management is set to turn your monitor and harddrive off after 30 to 45 min.

If the computer is however working for 30 to 45 min while you doing stuff and it shuts off, the there is an internal problem "Hardware"

I would suggest you check to see if the power management is set to turn off monitor 30 min and harddrive after 45 min. IF that is not so, then we go on to the next test.

It could possibly be your processor fan is not working so once your processor gets over heated it shuts off the computer.

Turn off the computer, remove the case "this is only if you know what you are doing" with the case off, power on the computer and see if the processor fan is working.

You can get back to me and I can walk you through it.

Hope thiss help.

Have you tried unplugging overnight? Sometimes mine gets screen garbage and that clears it up. Of course, now it says "Auto Scan Required" every time I power up. Maybe I should've grabbed that after Xmas 32" at Fry's for $400.

Black screen


Most likely suspect would be a bad solder connection. The connection heats up and becomes an "open" circuit like turning off a switch, and then as the set cools down the connection "makes" again allowing the set to come on. Parts should not be required as I consider this brand to be a "disposable" TV.
