The PC/DVI is an input to the TV You need an aux out or monitor out. If you try using the PC audio input you won't hear anything.

I had this problem with a laptop of mine it's the led just replace the screen

do you have the rest of the model number like ws wd in front of the number . and have you checked the bulb i suspect you have a DLP Tv Set and you may have a lamp failure

The first thing to replace is the lamp. Google your model number and "lamp" and you'll find several sites that sell them. It isn't difficult to replace yourself and isn't very expensive. Good luck.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it.

Count it carefully. If you wish to get some details, check the site linked here.

Sounds like you need to replace the lamp. An original Mitsubishi lamp will last 7 to 10000 hours. It's a no brainer to replace. Buy the lamp from Mitsubishi or a dealer. Do not buy one over the internet. Those are awful...
