Model# 27d302 problem: vertical initial on check tv and found out that the vertical IC LA7840 is burnt together with D422, do you happen to know the part number or type of diode is this? Do you have any other idea what causes this two component to fail? are there any thing other than the two component(s) that you think is/are broken? or it need to be replace to make it work right? do you have any schematic for this model that you can send me? or atleast for the vertical section of it. thanks in advance John ex-JVC Philippines Inc. tech 1995 - 1999
