My laptop makes loud beeping noise and screen comes up all fuzzy & crazy

One of the things is to hook it to another monitor and see if that still happens. If it does not then it is most likely the screen on the laptop. Not to worry though it could be the cable that connects the laptop motherboard to the screen. When you open and close the lid, it flexes the cable and the little wires in can break. The cable is not cheap though. One way to test this is to change how far the lid opens by flexing it open and closed to see if the screen changes. If it does then it is that cable.

Blue means that your system is not charging, when it is charging it should be pink/purple. when the battery is full it will turn blue. If the blue/pink light stay on it may mean that your battery is no longer charging completely. If it is still under warranty, get a replacement battery for free... otherwise it may be time to invest in a new battery.

replace Main PCB (it has the I/O ports & circuitry on it)

Maybe the cpu fan is fubar - check that out.

hi
This is not a tuner problem . The blue color is missing and the cause is the main board if you are handy with tools you could find the part#
printed on he board and find it on ebay

You could have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

OK did you ever try to hack your system did you open the inside of it did you drop or smash it or leave it in extreme temps if not it might be the result of poor cable connection,first turn off your Xbox 360 and check out the cables that are connected to the system. Remove them and re-connect them firmly. Now switch on your Xbox 360 again. There is a good possibility that you will find the fuzzy purple screen gone. If you still find a fuzzy purple screen then this might be a bit more complicated problem that your system is experiencing. Usually system overheating is one of the major reasons that cause various Xbox 360 errors

I have a new screen that I will put in it for $24.

try to replace the video card , that causing the different colors.

The beeping noise is usually related to the Horizontal out put transistor or flyback being faulty or one of the coils are loose near the flyback. If you remove the rear cover without touching anything can you tell if the beeping is coming from the large transformer with the red wire coming out of the top or is it coming from a black transistor on a aluminum heat sink.
