Any TV techs out there?

Thanks guys. will have a good look for dry joints on all the boards.

If that doesn't work Joe put it on the rubbish heap & buy yourself a decent set!

The picture is awesome on this unit. Sh!ts all over any other el cheapo set available now so I would like to keep it if I can get it going for little outlay.

couldn't see any dry joints visually or by tugging components. However at the top left the board looks discoloured under 4 resistors

if you have a soldering iron just remelt all the solder points, you will only see the cracks from the back of the board and sometimes they are very difficult to see regardless. They usually look like a little ring in the solder, try not to spend to long on the solder points otherwise you will lift a track, quickest way to do this is to melt some solder on the tip of the iron before you touch the board, that way the wet solder on the iron transfers the heat straight away and your not left holding the iron excessively long on the board for too long.

Regards the resistors if you have a multimeter you should be able find the values on the internet, the coloured rings will give you this, then measure them up against what they are supposed to be.
Also go over all the caps, make sure they have been left to discharge for at least a few minutes after being plugged in before touching them, you can sometimes see if they are buggered just by a visual inspection as they tend to bulge out, sometimes it can be as simple as the top being slightly raised/domed up.

Don't really have access to my Tech at the moment as I'm in the USA holidaying with my family and he's the one id need to speak too to bounce more in depth stuff off.

Thanks DM. I will break out the soldering iron & give it a go.

well it isn't the z-sus board (like I suspected). got one delivered today off ebay, installed it & problem not fixed. Back to square one

[JT]

Fixed!! there were some dodgy solder joints on the main power board.

Well done JT....

Good on you for working it out, so many people give up on fixing anything these days!
