Picture goes off and on every couple of seconds

The device sources and the inputs have not been set to the correct mod.There could be a problem with the TV it's self for it to be turning off like a problem with the power supply for the TV.

You have one of possibly two issues. Issue one bad memory or memory slot. Test each memory chip individually, one will probably cause the computer to blue screen and that will be the bad chip. If they all cause a blue screen, test in a different slot. If this works then you have a bad slot, if not the try issue two.

Issue two, your OS has become corrupted. Do a fresh install of windows (wipe everything out), then reload your drivers and all software.

hope this helps

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a few seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

This can be caused by a hardware failure (e.g. hard drive, etc.) or an operating system (OS) issue. Either way I would recommend taking it to a computer repair shop so they can diagnose the issue.
If its an OS issue most likely the cheapest way to fix it will be reloading the OS on a new hard drive(because its cheaper to buy a hard drive then have a company backup your data) then plug in your old hard drive to get access to your data.

When you power up listen to hear a couple of beeps that come from the computer. If you do not hear them then you have a problem in your i/o processor and that is unfortunately on the only one main board.

I think it maybe time to buy a new monitor

I would replace the control box assembly that is the most common issue with those TVs

my polaroid model #3200  does'nt come on!  the light goes from red to blue and nothing,the picture stays black with no flashing or flickering

I have the same issue with my phillips tv. There is a blue ghosting/pixel issue on the left side. It's still under bestbuy's warranty so I am going to call it in for service. It's more visible with hdmi and high resolution inputs. It does take a while to happen. Looks to be a bad screen possibly.

Picture tube issue. How long have you had it? Call the manufactor.
