Alba lcd32880 32inch

[LEEDASH]

Firstly hello to all,now heres a problem I'm facing,I have a 32 alba LCD 32880 model which has discovered a fault where it only stays on for 5 seconds,then switches off.
We'll I bought a faulty set of eBay which had a broken screen but stayed on longer than the 5 seconds,so by doing a bit of research on here and google,I just changed the power board from the broken screen and hoped for the best,we'll not all,it dont work :( the second set with cracked screen seemed to be a facelift model but
 model number is exactly the same,only difference was mine had 2 hdmi ports and this one had only one and a VGA port,but board inside was near identical even down the board number.

The original problem was the screen only stayed on for a matter of seconds,was told it may be the power board no working properly,ok,so I sourced another tv set which only fault was a smashed screen so I knew the power board was ok,as the set stayed on.
So by swapping the board into the original set it still acted in the same way,the only thing I noticed was the light on the top board would only stay on for a matter of seconds,I was unable to try this board from my donor set as it was different to the original,still a lcd32880hdf but donor set was like a 'facelifted' version,hence why I need to try another board.

put all oridginal boards back in in to set and try disconnecting one side of caps c231/230 if set comes on faulty inerter discharge caps ..i think they are 650nf 5kv..

hi
if you have changed the power supply and still same prob screen faulty one of
the ccfl tubes the inverter transformer is on the psu
there are some 5pf caps 5kv wkd near plug for screen cause this fault
but would seem strange that the psu you changed is giving same fault
