According to the specs you have a 32" TV there which should weigh in the neighborhood of 25 pounds. It looks from pictures that it is presently mounted on a simply one direction down tilt bracket. Correct?
If so...can you access the wood or material in back of the TV to remove it and mount a different bracket?
If so...then any number of two arm hinged articulating brackets should be mountable...not in their usual horizontal configuration ...but in a vertical configuration to allow you to swing it down for easy viewing and swing it back up when done.
Something like this but mounted 90 degrees from shown. You might need a backing plate of plywood or metal to distribute mounting forces.
I note that this particular one can hold 40lbs.

But there are lots of others and you might look in Walmart & BestBuy for some hands on comparisons.
