Screen turns like a blueish color???

Contrary to popular belief, any display product can have "Image Retention" and even "Burn-In". This is true for Plasma, LCD, LCOS, DLP, and CRT. I do not see a model number provided, but I would bet that you have an LCD rear projection TV rather than a DLP projection TV. If this is the case, the Blueish and Greenish blotches you are seeing on the screen are the result of UV light damage. UV light will move heavily damage the Blue panel, due it's short wave length. So, bad Blue or Green (absence or Blue) is typically the the first visual indicator of a problem. Replacing the Light Engine will resolve the problem.

Problem self righted.

Your tube is failing.

RAM problem. Fix the RAM properly in the RAM slot.

If the Blueish problem appears try play around with the VGA cord and see if the Colors comes back, if not, try hiting the monitor to see if the lines and color problem comes bcak to normal. If not your monitor's circuit board needs some dry solder, it could be the cold solder problem. Cheers.

Are you using component video cables? If so, check that these aren't loose on either end. Next I'd consider that whatever video cable/input might be bad, and switch cable or cable type... i.e. switch from component to HDMI or vice-versa. Then change up the source (cable box versus DVD player). If you're still seeing blue at this point, the TV internals are the bad.

If the red gun stops working it could make the picture very blue-greenish. This could be caused by a number of problems, including a coolant leak, but it's most likely a bad electrical connection somewhere in the set.

Best left to a professional repair guy, frankly.

The blinking 5 times is an error code meaning that the white balance has a failure. And because you are experiencing a blueish screen then your problem lies in the circuit of the blue picture tube or possibly the blue tube itself is starting to go bad.
