Ron, the amount of weight is proportional the the ride height of the front. If the ride height is back to where you started, 100% of the weight is restored. You can achieve this by raising the rear even higher than you started if needed although that increases caster and makes the truck steer funny.

The amount of load removed from the front axle is directly proportional to the vertical downward force on the ball, directly proportional to the distance from rear axle to ball, and inversely proportional to the TV's wheelbase. The amount of front end rise is directly proportional to the amount of load removed and inversely proportional to the spring rate. You cannot change the front-end load by raising the rear -- unless you have a trailer attached with WD applied.

Think about a wheelbarrow, the higher you lift the handles, the more weight goes on the front wheel and the lighter the handles get. When you dump it you stand it right on the wheel and the handles are weightless.

The CG of the load in a wheelbarrow is considerably higher than the axle and relatively close to the axle. As you lift the handles, the horizontal distance from load CG to axle decreases quickly making it easier to raise the handles.
Raising the rear end of a TV is nothing like lifting the handles of a wheelbarrow. There is virtually no change in horizontal distance from CG to pivot point. If you get the CG over the front pivot -- you're in big trouble.
