Question about JVC AV-48WP74 48" Rear Projection HDTV-Ready Television
Remove the front grill. There are 2 screws on each corner accesable from the rear and 2 screws inside the front door. Push down on the grill and it will unsnap. Remove the pressboard coverplate . You should see the convergence board, it is about 12" long with a big aluminum heat sink. The board can be removed by pressing on the tabs that hold it down. Be sure to mark and unplug the molex connectors from the board. One of the connectors has to be unplugged from the chassis because it is fixed to the board. Once removed you can easily get to the IC`s mounted to the heat sink. Check for any burned resistors near the IC`s.( 2.2 ohm likes to burn) The convergence can be done through the customer menu using the remote. There is no special formatting necessary. Use the number pad to navagate and the select key to change red & blue.
