Hi Chris
The fault is a rather spectacular wire link destroying blow up around T20 see an earlier picture posted by Alun, as I haven't worked out how to post mine yet,

I have just received the repair kit from OHM - great service BUT unfortunately IC21 (FSD200) was riveted into the antisatic foam damaging its legs and so I hope to get a replacement next week.

I have seen old posts which indicate this is an old known issue and it puzzles me that no one has come up with a solution. Comments seem to indicate that the power supply fails on initial power up, which is what has happens to this and two other power supplies - so perhaps it is a surge or transient problem???
However I hope the next post will be one of triumph

Hi, I got this TV stuck in standby with no visible component damage on any PCB and the 5v & 24v are working fine. I assume by your post this may be a firmware issue?

If it is firmware would it be on the removable 'V1_00' BIOS chip or the soldered one on the tuner board or is it one of the other chips?

I have a chip programmer so am I able to re-flash the firmware and if so where can I get a copy of it?

Thanks in advance.

Phill.
