Specs: windows 7, 4gb
As stated before I am running Windows 7 Ultimate 64 bit. HP A1410n desktop. Using TV as monitor and screen goes blank every 5, 10 to 20 min. Says no input. Hit menu button on TV and everything is fine or another 5 to 20 min. Does this only when using the PC on TV (watching movie, playing games or surfing). Gave up on it but I just installed Linux Mint 15, 64 bit, two weeks ago. It's running with windows (or along side of windows). You have to select which OS to use at start up. I can use Linux or let it sit for 3 hrs. with no problem. Screen does not go blank. Any suggestions why it goes blank on Windows and not Linux?

Do you have a screensaver enbled or have power options set to turn off the monitor?

No. It will even go blank when Windows is loading. But not in Linux. I thought that maybe it was a onboard video card issue but since it does not do it in Linux it has to be something else. I even went as far as reinstalling Windows before I put Linux on it.

Yeah, it doesn't make sense that it'd work with linux and not windows since you're using the same hardware for both. But if hitting the menu button on the TV gets it going then maybe it's the TV. Maybe the TV is having a problem displaying the resolution or refresh rate. You might see if altering those settings has an affect.

Done that. Even messed with the (Phase) on the tv setting. Could it be some thing in Windows?

I meant the video settings in windows. If the windows settings are different than the linux settings then maybe that's the reason. Offhand I can't think of anything else.

Yes I have done that. If you mean resolution, I matched the resolution same as Linux. Tried every setting in Res. That's why after messing with it for what 2 mons. now I'm at my wits end. Maybe somebody else has an idea Thanks!!

You might try temporarily using a regular monitor. It the monitor acts the same way then it's the OS. If it acts normally then it's the tv.

My guess is it's the tv and it's somehow seeing the linux signal differently than windows. Try a different tv input if more than one is available.

Hooked one up and it does the same thing.

You hooked up a monitor and it does the same thing? Then the problem is in windows--drivers, video settings, power down options, screen saver--or maybe something else I haven't thought of.

I went back the first time you asked about that stuff and rechecked all of it. "EVERYTHING", Hard Drive included, is set to never shut down.

Any screen saver that was enabled would be through display properties and not power settings but it would only take a mouse movement to shut off a screen saver.

The only other thing would be some peculiar setting with your drivers in display properties.

Well there are some power options in cmos/bios setup. You might check there too. It could be linux is ignoring them and windows is using them. Maybe alter the APM/ACPI settings there.

But I'm really running out of sugestions.

OK I don't and never use a screen saver on any PC. Will check into the others you listed later. But I did get a Windows update the other day, which has not shown up on the other PCs. It only came to this HP a1410n with the problem. It was/from (LifeWorks Technology Group LLC. Input-USB Human Interface Device) Googled it. Didn't fully understand what it was for but I went ahead and install it. The only other thing that has been acting strange since I reinstalled Windows is Peerblock. It takes anywhere from 3 to 10 times to load after I click the run button to load PB. It gives a message > PB is not responding - Windows is looking for a solution. Removed and reinstalled PB several times. Now it, PB, did not do this before I reinstalled Windows. Before I reinstalled Windows I did a complete format of the hard drive.

I'm not familiar with peerblock/peerguardian but it has its detractors:

It doesn't seem like it would cause the video blanking but you might want to uninstall it and leave it that way and see what happens. The lifeworks update is legit and I couldn't find anyone posting problems associated with it.

If you boot to safe mode and run it there for awhile, does the same thing happen?

OK update. I just finished rebuilding a eMachines W3611. Only had 1-1gb and 3-512gb of ram to put in it but it works for now. So I hooked it up to the TV and been using it for 2 days. NO video problems with the TV not getting a signal. So does that tell you anything as to why the HP a1410n shuts off as explained above?

It just confirms the problem is with the HP and not the TV but I can't think of any possibilities other than what I already mentioned. It's a puzzler.

Yea figured that. Could it be something with the windows installation? I know as far as I remember it didn't do this before I reinstalled Windows. The reason I did that was because I put Linux on it but did it wrong, (it worked but I installed the wrong version), but couldn't figure how to delete Linux. So it was easier to just= "wipe it all and reinstall"TM <<sounded cool. Didn't have much on it anyway. I looked into the APM/ACPI settings but that didn't help. I wish somebody else would weight in on this. Thanks again. I'll let you know what I find out.

Yeah, it would be good to have input from others but this thread is a few weeks old and it's doubtful anyone will scroll far enough down to check it.

It doesn't seem like it would have anything to do with the windows installation but to check that I guess you could do a reinstall.

Wasn't knocking you, just two heads are better than one. In this case many. So I guess I will reinstall Windows. Now what the best way to do a HDD erase? I have the Hirens boot cd. What do you recommend?

When you boot the windows disk and start the installation process it should come to a point where you can delete the existing partition--I'm not sure of the exact steps with windows 7 but it should be clear. Do that and then recreate the partition and continue with the install. Deleting the partition won't wipe it but will leave what's on it as unusable and the new install will overwrite everything.

Will that take off Linux also. Linux is running either with or beside of Windows.

I can't say for sure because I've never it. If you're sure to delete the windows partition and not the linux I think it'd go ok. Although I think sometimes it removes the boot loader menu and just goes into windows. You might want to repost in the Linux forum. People there should know how to do it.

Update. Instead of deleting HDD that was in it and all that mess. I had another newer HDD with Windows on in I stuck in. It's one that I used the same PC to install Windows on. So started doing updates and got a message about "Away Mode" not compatible with 64bit. So read up on that. Rechecked all the settings, Sleep, Hibernate and so on. All power options. Screen res. Everything I could think of. And it does the same thing. May go 10 sec and turn display off or maybe 4 min.36 sec. and turn off. Sometimes after 20 sec. three times in a row. You get the picture. Just hit the TV remote menu button and it comes back on. Now remember it didn't do this when hooked to a different PC. Can I repost this thread?

You could start a new thread basically describing what you've done so far and the results. Then you can include a link to this thread for additional details.

OK so read the above to reset your mind. But I finally got another Flat screen TV, different brand, to use as a monitor. And it does the same thing. Display cuts off!!. So it must and has to be something in the PC settings. I'm still not sure what the Away Mode has to do with it. I guess I will repost when I get more time. Thank again!!!!!!

Can't remember, did you try updating the video drivers?

Since it's got to be the video adapter or its drivers, if you're using on-board video maybe you should add a video card, or a different video card if you're already using one
