Hi guys,I have had a few of these screens now with the same fault.
plug set in set is dead no st-by light.strip down remove p.s.u. & power up ,various voltages now present.the cure is to replace 2 -22uf 50 volt working caps one in primary of p.s.u.to do this you have to desolder 2 transistors on heat sink that covers primary power supply.there are only 2 caps in primary smoothing block & the 22u.f.
The second cap is ref c26 sits just below centre of p.s.u. again 22uf.
P.c.b. is marked HOAU242001A PTNO 6693006610.Hope this might be of help to some of you.
