In most cases when you have audio but not video, the failure is with the Ysus board, very common failure with plasmas.
Check this website to see if they have the assembly you need but only if you feel comfortable fixing yourself.

Call LG and see if your t.v. is on the replacement program. some of the t.v.'s they had produced had faulty Ysus cards.
they may repair or replace it free.

First unplug tv from power fro one hour or so to reset the unit.
Check also all connections to receivers, dvds, cable, sat etc., in case it is a cable problem.

You need to check plasma screen connectors inside your TV. The unit must be taken apart and Ysus Zsub boards removed and put back in place.
If this does not fix it, you will probably need to replace your Ysus card.
Unless you are an experienced electronic DIYer this job is better done by a technician.

    If it is a fuse, the tv should not start at all, when a fuse blowsin this unit, either you get no power at all, or the unit keeps in stand by, as an internal switch will keep the device off. Regarding the lamp, it is a plasma TV, there is no lamp that can cause picture going off completely (black screen) on this kind of TV.
    When plasma screen itself is defective, you often start getting picture problems before it goes.
    Looks more like some connector to the display is defective or misplaced.
    Plasma screen is controlled by pcb boards, if connectors are ok Ysus is the board that usually goes quite easily and it is often cause for the problem.

Hi,
No repair or part replacement is being offer from any brand company for their Plasma vision any more. Many brand companies are offering Plasma customers to exchange unit with LCD on discount rate. Please ask LG if they have any exchange scheme under way in your area.
I would advise you not to waste time and money to repair plasma tv. now its up to you what ever you decide.
Regards,

I will assume that you don't see any menu displays as well. This means that the plasma is not displaying anything. That would eliminate the video processing section. The menu is generated AFTER that point. The problem could be a loss of power to the plasma section or a digital processing problem. Is the set under warranty? If so, request warranty service. Otherwise, update this and we'll walk through some diagnostic steps.
