    Saem problem occured with mine yesterday. Small pop and then screen went blank, picture ok. I've seen various other threads detailing some boards that need to be replace as a result. Anyone know how easy/difficult this would be for a novice?

    No picture. The sound is fine. LED Power light is green (when turned on) or red (when on stand by), as usual.

    appartnely as it's a HD tv it's going to cost a bit more than SD tv, a coupld of baords needed replacing so am looking at the $700 mark, as to which boards, I'm hitting a bit of a brick wall

Brought the set to my local TV technician last night, he's going to call me today to inform me what the problem is. He's indicated that it is mor than likely the y-sus board whcih will need replacing, apparently for these HD sets they're not cheap, around $500 - $600.

After having done a bit of research I had looked into sourcing the boards (apprantely some come in a kit form, 3 boards included) direct from the Australian Supplier (Statewide Appliances in Adelaide, SA), however it turns out I was sourcing boards for a different model. Pity as it was only around $100 for the kit.

Will keep you posted!

    Sorry for the delayed post, however this will not probably be of much use, the techo replaced a couple of boards, total cost of $750 including labour. Now works fine.

    Sqezzy: Not much help in regards to which fuse to replace, but i guess that's the way things are made/treated these days, just rip out the old one and plug in a new. I'd be interested to hear in what your final acheivements were though in case this happens to me again.

The picture on my lg tv has gone dark. Every button on the remote is working except the menu button.The button on the side for menu is not working either.

Check and repair the remote control. It sounds that it need cleaning. But lack of brightness to a Plasma screen might be to a faulty Z Sustain board. Check this for more details about the TV fualts, and to how to repair and clean a remote control.
