The 2 blinks are an indication of over-current. This is usually because of a shorted component. The most common is the horizontal output transistor. This will be a 3-legged part attached to a heat sink close to the flyback transformer (part with red wire coming out the top). This transistor will be marked C4856 or something similar. Update this with the exact marking and I'll provide you with the full part number and approximate cost.

Reboot the machine in safe mode and see if it loads windowns. If it hangs at MUP.*** then most likely you have a bad sector on the HDD. If this is the case try this fix......
Windows Start-up Errors
Step one, you need a Windows XP CD. If you only have a recovery disk set like the ones from HP or Compaq they will not do what you need done. Under normal circumstances however, you can use a Dell disk because the Operating system is on a stand-alone disk. All retail versions are also acceptable as well as upgrade disks. For a rule of thumb, if the disk has the Microsoft hologram it should work. You can order a boot up floppy disk from here: http://support.microsoft.com/kb/310994 with this file, if you know how, you can use “ImageBurn” to burn the file into an ISO file which can be burned to a disk. Now make sure your computer boots to the cd rom first. If you know how to do this skip on down, if you don’t, while the computer is first starting up and you see the manufacturers splash screen, tap F12 (some computers it’s F9, others it may be another key, you may have to watch and see if the computer lists the key strokes for getting to the boot menu. If you still cannot find it, boot into the BIOS settings and change your boot order there. Save your settings and exit, the computer will now seek the cd rom as its boot source first.
Place your Windows disk in the computer and start it up. When you see the test at the top of the page “Press Any Key To Boot From CD” Just hit the space bar to activate. The next screen you will see will most likely be a Windows setup screen, when you see this press the “R” key to get to the recovery console. It will get there, it may take a little time, patience. Once it loads you will be given a choice of Windows installations, there should only be one, if there are more, always pick number one. It may ask for an administrators password, if you have not set this particular password, then just leave it blank and press enter. The next prompt you see is:
C:\Windows>
You need to type the following:
cd \
hit enter. Pay close attention to the spacing between the characters. There is a space between the character “d” and the “\”
You are now at the ROOT of the drive, this is where basic commands can be given and changed. You should now see the following:
C:\>
Now type the following:
CHKDSK /R
Hit the enter key.
The chkdsk /r command also includes the P command and will also look for lost recoverable information in bad sectors.
There are occasions depending on how corrupt the system is, that this process could take several hours, so be patient with it.
Now, after chkdsk has run type the following:
FIXBOOT
Hit the enter key.
It may prompt you with a warning, that’s ok, just continue. When fixboot has finished, type: EXIT hit enter and windows will reboot. When the system reboots, tap the F8 key during this time and you will see the multi-boot menu come up. Scroll to the title “Last Know Good Configuration” and hit the enter key. If you were having some simple drive errors this should have fixed them.

No,
There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
