just a little update
the tv is working now on its original power supply!
as ive repaired that to component level
replaced 2 mosfet chips and it burst into life
for anyone interested the mosfets are a fast switch which turn 350vdc back into rough AC before being converted into the many rail voltages in a TV
price break down
faulty tv £25
capacitors £4.80
Mosfets £6.30
Replacment power supply £29.99
i should be able to sell the PSU i bought from ebay
to recoupe some of that money
but if i dont a working 37" HD lcd tv for £67 aint to bad.....
down side is now the kids want it in their bedrooms
il just add a few key words so google bot will draw people here
