This set has the 9-1942 and 9-1978-01. Unit had no HV replaced 9-1978-01 had HV but tubs would not light up.Replaced focus block. Set now has HV and a raster. No picture or menu.Set came from buddy buy rite that's why it has a off the wall model number.Can the focus block be bad or can a bad focus block take out the new 9-1978-01. Need help.
