Try unplugging z-sus from power board. If the tv stays on, replace the z-sus but check the heatsinks on the new board. If they overheat, you'll have to replace the control board as well.

I have this set in also, unplugging the z sus gives a picture again but snowy! what are the chances of a replacement Z board being a long term fix? have heard they can pop again soon after being replaced.

Also seen repair kits on Ebay?

Any advice welcome

thanks Ronnie

Ok I bought the repair kit for this fault, it has worked, it has parts for the z board and a load of capacitors for the control board.

But the heatsink on the z board gets VERY hot! and control board giving 4 flashes even tho the picture has been restored, not leaving it on for any lengh of time as I think the z board would blow again!

Anyone any ideas?

thanks Ronnie

Maybe a new logic board will fix it. I believe it has upgraded software to fix this problem.
