Dick Smith 37" LCD TV Green screen problem

jimjoe123, take the receiver to a TV technician for diagnosis and repair.

You can get yourself into a lot of trouble and additional expense by attempting a repair yourself.

Novices lacking the appropriate knowledge (and with no practical experience) waste other people's time in attempting their own repairs.

Yes, these forums are about helping each other, but there's a limit to what can be achieved "by remote control".

The click sound you indicate that is heard preceding the screen malfunction, may be an electrical sound, not a mechanical one. You may be hearing a small arc, or the sound of an arc occurring -inside- a faulty capacitor - if that were so, it's possible that fault may introduce a voltage spike and/or noise on a power rail, which results in the t-con board loosing the plot until it's power cycled. It could be as simple as bugs/dust behind the inverter board ~ I had a 1500w ATX power-supply 'explode' while being tested, and all that turned out to be was a ball of dust had coincidentally built up on the 400v storage cap solderside pin stubs, and just because the humidity that day was 95%, the dust was very conductive and BOOM.... not click =)

Also, a bad capacitor may go into a shorted condition, and 'relax' (removing the short) when the power is turned off, and then the short return after an indeterminate time ...and with cracked or broken solder joints, any vibrations at all can trigger such faults.
