I think that does have a removable light box. A quick test of the HOT for shorts will show if you at least need a SMPS/deflection board.I don't repair those any more. If so, maybe a splitter block.Common ones.Go to www.tritronicsinc.com , enter your model number and pull up a parts list. Phil Phil Bader, Pres.
