So I fixed the crack, then ran some solder and a thin wire along the

The thing is, it's still not working,


I have worked on dropped tvs many times. as others here have said,
chances are you have more cracks. i've been caught out like that
before.


Also, I have had the pcb flex on landing and some transistors and
regulators worked loose from their solder pads. That was on a Hitachi
28" widescreen set. look for heavier components , transformers,
heatsinked stuff. BTW I think the brown component you mention may be a
red herring. I'd look elsewhere first and come back to that later.


check the pcb on the tube also, in case.


keep at it

OK, so I finally had a chance to have one last look at it a couple of
weekes ago before deciding to throw it out and, sure enough, there
were a few more cracks that I hadn't seen the first time round (the
lighting in the room it was in is fairly bad).
So I got out my tools again, patched it up, plugged it in, stood back
and, with a long stick in hand (maybe overly cautious ), switched it
on. Badda-bing, badda-boom - I've got a picture.
So I'd just like to say thanks to everyone here for all the helpful
tips, it's much appreciated.
Cheers,
ANT
