Ur tv have convergence problems,it dead.U must have soldering tools and know how to solders to fix the convergence problems.U must replaced 2 STK convergence ICS,and some or all it resistors.Tries websites like Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.
this set(AV56wp74) was first made in 2003----if you use the remote for the set and go into the customer menu---select convergence----once there see if the red and blue will move left/right and up/down----if either color will not move in any one of these directions----you have a bad convergence IC--this set uses 2 of the STK-392-110 output ic chips---both need to be replaced and the set adjusted with the original JVC remote control. I hope this has been helpful.
Replace the lamp, also the shut down time is correct the unit must allow plenty of time proper lamp cooling. otherwise the lamp life will be greatly shortend. normal lamp life is 3000 hrs.
lamp replacement may require an internal limp timer reset have a qualified tech replace the lamp.
