When I turn on my TV, a blank grey screen appears. The channel number 3 shows in the corner for a few seconds after turning on, but other than that, nothing really works. I have done power unlock and menu unlock. It seems that most things are not enabled. The remote can only turn the TV on and off and pull up the menu. The guide button does not work. :(

There is a button lock in the menu of the television. Using your remote access the menu screen and unlock the buttons.

I have a 19" ViewSonic and if you hold down the 2nd and 3rd buttons together under the screen, counting from the LEFT, it will disable the Powerlock.

No there are no fuses in that type of flat screen TV. If it will not power on at all then it sounds like a failed or at least failing power supply inside the TV.
Unfortunately this is a very difficult repair, and unless you are an
electrician I would not recommend attempting it. You will want to
contact a local TV repair person in your area if you are sure this is
out of warranty, more on that in a bit here. This is actually the
most common problem with this type of TV, I see it every day, it just
happens - sometimes with new TVs and sometimes it takes many years for
it to happen.
If you think it may
still be under warranty please contact the manufacturer to file an
RMA. If you happened to purchase the TV with a major credit card (not
a debit card) there is a good chance it may still be under the free
extended warranty most credit cards place on electronics. Please
contact your credit card company to inquire if they do this, and they
will be able to file the claim and get you a refund for the TV.
If
you want to attempt the repair yourself please let me know and I will
get you the part number and a place you can purchase it from for what
you need.
So sorry that I don't have better news but it is definitely a power issue internally.
Thanks
