        If ever in doubt, see attached Excel spreadsheet, it will give you PASS/FAIL.

              Ok the tv run for a week but went off yesterday seems to be totally dead now I've not checked the voltages due to being a work, originally I sent the tcon off for repair could the tcon cause this ? I'll be checking more in the morning

                A shorted t-con would cause the TV to be stuck in standby, but it wouldn't cause absolutely no power - that would be power board or main board IMO.

                        So it sounds like bad luck, unrelated chance failure...

                          Whats the model number of the main board?

                          Sounds like a bridge rectifier to me ...

                                  You can get the SCH from Tom website.
                                  http://www.tgohome.com/ServiceManual...&Search=Submit
                                  That fuse is for feeding the Voltage to the standby power supply and the inverter circuits, so you have shorted circuit some where.

                                      Remove that fuse FM802S, see if the main one still pops? Maybe consider building a lamp test jig

                                      This will stop you popping new fuses...

                                        I'll look more in the morning to be fair with limited time and my son moaning that he wants his tv back might be a option to get a replacement board
